Elapsed Time Formatting in Excel Format Cells

A weekly total that appears to reset after 24 hours is usually a time formatting issue, not a problem with the SUM formula. Excel stores time as decimal days, so a value of 1 equals 24 hours. The standard hh:mm format shows clock time and wraps back to zero after 24 hours. Use elapsed-time formatting instead.

The problem

This issue came up in the r/excel community discussion about fixing a 24-hour reset. It affects businesses that use an Excel working hours sheet to total employee shifts, weekly hours, overtime, or billable time.

The formula in the total cell is:

=SUM(J8,J13,J18,J23,J28)

This formula adds the five referenced cells. There is no obvious problem with it if those cells contain valid Excel time values.

The likely problem is the cell formatting. With hh:mm, Excel treats the result as a time of day. Once the total reaches 24 hours, the display starts again at zero. For example, 30 hours may appear as 06:00 because Excel displays only the time remaining after complete 24-hour periods.

The underlying value can still be correct. Excel represents time as a fraction of a day. A result of 1.25 means one day plus one-quarter of a day, which equals 30 hours. The display changes, but the stored calculation does not.

The solution

Change the total cell's custom format from hh:mm to [h]:mm.

The square brackets are the important part. They tell Excel to display elapsed hours instead of clock hours. A result of 30 hours will then appear as 30:00 rather than 06:00.

Microsoft's guidance uses [h]:mm for elapsed time that exceeds 24 hours. The h displays hours, the colon separates hours from minutes, and mm displays minutes. The brackets around h prevent the hours from wrapping after 24.

The formula can remain:

=SUM(J8,J13,J18,J23,J28)

SUM adds the values in the listed cells. The commas separate each cell reference. You could also use a range if the cells were next to each other, such as =SUM(J8:J28), but that would include every cell between J8 and J28. Keep the original formula if the gaps are intentional.

Use hh:mm when you want a time of day, such as 08:30 for a start time. Use [h]:mm when you want a duration, such as 37:45 for total weekly hours.

How to apply it

1. Select the cell that shows the weekly total.
2. Open Format Cells. In desktop Excel, right-click the cell and choose Format Cells, or press Ctrl+1 on Windows.
3. Select the Number tab.
4. Choose Custom.
5. In the Type box, enter [h]:mm without the spaces.
6. Select OK.
7. Confirm that the total now shows accumulated hours, such as 30:00 or 42:15.
8. Check the formula bar to verify that the cell still contains =SUM(J8,J13,J18,J23,J28).
9. Test the sheet with a known total. For example, add entries that equal 25 hours and confirm that the result displays 25:00, not 01:00.
10. Apply the same format to any other cells that show weekly, monthly, overtime, or billable-hour totals.

If the workbook is used in Excel for the web, the calculation can still add more than 24 hours, but custom number-format options may be limited depending on the version and editing experience. When the web version does not allow the format to be applied, open the workbook in desktop Excel, set the cell to [h]:mm, save it, and then reopen it online.

Do not change the source shift cells to [h]:mm automatically. A shift beginning at 08:00 should normally remain a clock time. Apply elapsed-time formatting to calculated durations and totals.

If shifts cross midnight, the calculation needs separate attention. For a start time in A2 and an end time in B2, a basic duration formula is:

=B2-A2

This subtracts the start time from the end time. For an overnight shift where the end time is recorded as an earlier clock time, use:

=MOD(B2-A2,1)

MOD returns the remainder after division. Here, it converts a negative-looking overnight difference into the correct fraction of a day. Format the result as [h]:mm.

For payroll or compliance reporting, consider storing the date alongside each shift. A time-only sheet can become ambiguous when an employee works across midnight or when managers review several weeks together.

Implementation angle

For a small business, this fix is a useful first step toward a more reliable hours process. An automation partner could replace scattered references such as J8, J13, J18, J23, and J28 with a structured table containing employee, date, start time, end time, break, and approved hours. Make or n8n could then send approved totals to payroll, invoicing, or a weekly management report, while Zoho Creator could provide controlled data entry instead of an easily damaged spreadsheet.

Creator Scripts can build and check the Excel formulas, validate overnight shifts, and connect the approved hours workflow to the systems your business already uses. Book an AI implementation engagement with Creator Scripts at creatorscripts.com.

Frequently asked questions

Why does my total hours in Excel reset after 24 hours?

This happens because of the time formatting in Excel. If your total is formatted as hh:mm, it resets after reaching 24 hours, displaying only the time remaining instead of the total hours worked.

How do I change the time format to show hours over 24?

To display hours beyond 24, change the cell format to [h]:mm. This format allows Excel to show accumulated hours correctly without resetting after 24 hours.

Can I use the same formula for an overnight shift in Excel?

Yes, you can use a formula to calculate overnight shifts. Use =MOD(B2-A2,1) to handle the end time that occurs past midnight, then format the cell as [h]:mm to display the correct duration.

Ownership Percentages in Excel with SUMIFS

Ownership percentages become difficult when one company owns part of another company, and an individual owns part of several entities. Small-business operators often start with an organizational chart, then discover that direct ownership and indirect ownership require a structured calculation.

The reliable approach is to record each entity relationship as a separate row, calculate each ownership path, and add the results. A chart can show the business structure, but a clean data table should drive the automated ownership calculation.

The problem

This issue came up in the r/excel community discussion about automatically calculating ownership percentages. The example involves John Smith, who owns 25% directly of Dog Dad LLC and 32% directly of Cat Mom LLC. Those two companies have an ownership relationship with Pet Parents LLC, and the goal is to calculate John's total indirect ownership of Pet Parents LLC.

The missing detail is the relationship between Dog Dad LLC, Cat Mom LLC and Pet Parents LLC. Excel cannot infer that relationship from names or from a visual organizational chart. You must enter the ownership percentage for every connection.

For example, suppose:

• John Smith owns 25% of Dog Dad LLC.
• Dog Dad LLC owns 40% of Pet Parents LLC.
• John Smith owns 32% of Cat Mom LLC.
• Cat Mom LLC owns 20% of Pet Parents LLC.

John's indirect ownership through Dog Dad LLC is 10%. The calculation is 25% multiplied by 40%.

John's indirect ownership through Cat Mom LLC is 6.4%. The calculation is 32% multiplied by 20%.

His total indirect ownership of Pet Parents LLC is 16.4%, before adding any direct ownership John may have in Pet Parents LLC.

This is called cascading ownership. Each link in the ownership chain contributes to the final percentage. For a longer chain, multiply every percentage along that path.

The solution

Do not build the calculation directly into the organizational chart. Store the business structure in a simple ownership table.

Create these columns:

Owner	Owned entity	Ownership percentage	Path result
John Smith	Dog Dad LLC	25%	25%
Dog Dad LLC	Pet Parents LLC	40%	40%
John Smith	Cat Mom LLC	32%	32%
Cat Mom LLC	Pet Parents LLC	20%	20%

For a two-step path, calculate the result in a separate calculation table. Use one row per complete path.

Person	Target entity	Ownership path	Indirect ownership
John Smith	Pet Parents LLC	John Smith → Dog Dad LLC → Pet Parents LLC	10%
John Smith	Pet Parents LLC	John Smith → Cat Mom LLC → Pet Parents LLC	6.4%

The formula for the first path is:

=25%*40%

The first percentage is John Smith's ownership of Dog Dad LLC. The second is Dog Dad LLC's ownership of Pet Parents LLC. Excel multiplies them to produce John's indirect stake.

The formula for the second path is:

=32%*20%

To total all paths for John Smith, use:

=SUM(D2:D3)

SUM adds the indirect ownership results in cells D2 through D3.

If John also owns 5% directly of Pet Parents LLC, add that stake separately:

=5%+SUM(D2:D3)

This returns 21.4% total ownership. Direct ownership should not be multiplied by another percentage because it already applies to the target entity.

For three levels, continue multiplying:

=JohnOwnership*FirstEntityOwnership*SecondEntityOwnership

For example, if John owns 25% of Dog Dad LLC, Dog Dad LLC owns 40% of Holding LLC, and Holding LLC owns 60% of Pet Parents LLC, the result is:

=25%*40%*60%

That produces 6% indirect ownership.

The strongest model treats every path as a separate calculation. It is easier to audit than one complicated formula, especially when legal entities, partners and subsidiaries change over time.

How to apply it

1. Create an Excel table with one row for every ownership relationship.

2. Use clear columns such as Owner, OwnedEntity, OwnershipPercent, EffectiveDate and SourceDocument.

3. Enter percentages as actual percentages, such as 25%, not as text like 25 percent.

4. Confirm that ownership percentages for each entity add up correctly. If Dog Dad LLC has three owners, their stakes should normally total 100%, unless the structure includes unallocated shares or another documented exception.

5. List every complete ownership path from the person to the target company.

6. Multiply the percentages along each path. For example, use =B2*C2 for a two-level path, where B2 is the first ownership percentage and C2 is the second.

7. For a three-level path, use =B2*C2*D2.

8. Add all paths that have the same person and target entity with =SUMIFS(ResultRange, PersonRange, PersonName, TargetRange, TargetEntity).

9. SUMIFS adds only the path results that match the selected person and target entity. This lets one summary report calculate ownership for many people and companies.

10. Add direct ownership separately from indirect ownership.

11. Add validation checks. A useful check is =SUM(OwnershipRange), which confirms the ownership entered for one entity.

12. Format the result as a percentage with an appropriate number of decimal places. Avoid rounding the underlying values before adding them.

A practical summary table might contain Person, TargetEntity, DirectOwnership, IndirectOwnership and TotalOwnership. The total formula can be:

=C2+D2

Here, C2 contains direct ownership and D2 contains indirect ownership.

If an owner can reach the same target through several entities, keep each path separate. Do not assume that adding a person's percentages in Dog Dad LLC and Cat Mom LLC is enough. The ownership percentage of each intermediary company must also be included.

For a larger business hierarchy, a flat table is more reliable than manually editing an organizational chart. The chart can remain as a visual report, while the table becomes the source for formulas, checks and automation.

Implementation angle

Zoho Creator can turn this ownership table into a controlled workflow that stores entities, ownership relationships, effective dates and supporting documents in a structured database. Make or n8n can sync approved changes from intake forms into Excel or a reporting database, while automated checks flag ownership totals that do not reconcile to 100%. An AI assistant such as Claude can help generate and review Excel formulas, but the ownership relationships still need to be confirmed against the company's legal records.

Frequently asked questions

How do I track ownership percentages in Excel?

To track ownership percentages in Excel, create a simple ownership table with columns for owner, owned entity, and ownership percentage. Enter each ownership relationship in its own row to allow for easy calculations.

Can I automate calculations for indirect ownership in Excel?

Yes, you can automate calculations for indirect ownership by using formulas to multiply the ownership percentages along the paths. Use the SUM function to total the indirect ownership from different paths for accurate results.

What if ownership percentages do not add up to 100%?

If ownership percentages do not add up to 100%, check if there are unallocated shares or other exceptions documented in your records. It’s important to ensure that the ownership structure is clearly defined to avoid discrepancies.

Power Query: Load Newest File from Folder

Power Query can reuse the same transformation steps every day while selecting a new source file. For a daily work-items report, the most reliable setup is a folder connection that keeps the newest file and ignores older files. This avoids rebuilding the query or replacing files manually.

The problem

This came up in the r/excel community from someone downloading a daily report, transforming it in Power Query, and needing the workbook to use the next file without losing previous downloads. The core issue affects businesses that receive recurring inventory lists, sales reports, work queues, or operational exports in the same structure.

The goal is not to create a new query for every download. It is to separate the file import from the transformation steps. The import query identifies the correct file. The transformation query cleans and reshapes its contents. Once those query steps exist, a refresh applies them again to the next report.

The most practical approach is to store every daily report in one folder. The folder connection can select the newest file based on its Date modified value, so older files remain available for history or audit purposes. The original discussion is available in the r/excel question about updating a Power Query source file.

The solution

Use a two-part Power Query design:

1. A source query connects to the folder and identifies the file to import.
2. A transformation query applies the cleaning steps to the selected file.

This is usually better than a macro for the data preparation itself. Power Query records repeatable data transformation steps, such as removing columns, changing data types, filtering rows, splitting text, and combining tables. A macro can provide a file-picker button, but it adds code that must be maintained and secured.

For a daily report, the source query should:

• Connect to the folder where reports are saved.
• Sort files by Date modified in descending order.
• Keep the top row.
• Open the selected file.
• Pass its contents to the transformation steps.

The "keep the top row" step means Power Query retains only the newest file after sorting. Each day, the operator saves the new report in the folder and refreshes the workbook. The older reports remain untouched.

A consistent naming convention is still useful. Names such as WorkItems_2026-10-16.xlsx make the folder easier to audit and allow additional filters by file name. However, renaming is not required when the newest file is always the correct source.

A second option is a workbook-controlled file parameter. The operator can type a full file path into a cell, load that cell into Power Query, and use it as the source. This gives direct file selection without opening the Power Query editor. It is useful when the correct file is not always the newest one.

The folder method is more robust for a standard daily workflow. The cell parameter is better when an operator must choose among several reports or rerun an older date.

How to apply it

1. Create a dedicated folder for the daily reports. Do not mix unrelated Excel or CSV files into it.

2. Save each downloaded report in that folder. Keep the column names, table structure, and worksheet layout consistent.

3. In Excel, open the Data tab and choose Get Data, then From File, then From Folder.

4. Select the report folder. In the file preview, choose Transform Data rather than loading every file immediately.

5. In Power Query, filter the file list if necessary. For example, filter the Name column so that only files containing WorkItems remain.

6. Sort the Date modified column from newest to oldest.

7. Select Keep Rows, then Keep Top Rows, and enter 1. This leaves only the newest matching file.

8. Use the file's binary content to open the workbook or CSV. For an Excel report, select the appropriate worksheet or table.

9. Apply the data transformation steps once. Typical steps include promoting headers, removing blank rows, changing dates and quantities to the correct data types, and filtering out totals or notes.

10. Give the queries clear names, such as Source_LatestWorkItems and Transform_WorkItems. Clear names make the workbook easier to maintain.

11. Load the transformed result into a worksheet or the Data Model, depending on how the report will be used.

12. Test the workflow. Add a second report with a newer modified date, refresh the query, and confirm that the result changes to the new file.

13. Configure refresh behavior from Data, Queries & Connections, and the query properties. The source discussion recommends updating the query when the workbook opens, where that option is available in the Excel setup.

14. Document the folder location and file rules in a small instruction sheet. State that the report must use the same columns and that unrelated files should not be saved there.

The file structure matters more than the file name. If a new report changes a column heading, removes a table, or changes a date format, a previously working query can fail. Keep the report schema stable, or add validation steps that flag missing columns before the output reaches the business report.

If selecting a specific file is more important than selecting the newest file, create a small Excel table with one value containing the full file path. Import that table into Power Query, extract the path value, and use it as a parameter in the source step. The operator can then change the path in the worksheet and refresh the workbook. This alternative is more controlled, but it introduces a manual input that can contain typing errors.

Implementation angle

For a small business, this pattern can become a controlled reporting workflow instead of a personal Excel routine. Creator Scripts can connect the daily folder to a structured process in Zoho Creator, or use Make or n8n to place incoming reports in the correct folder and trigger the refresh workflow. A validation layer can check that required columns such as item ID, status, quantity, and date exist before the report is loaded. For teams looking to move beyond spreadsheet-based reporting entirely, Zoho Analytics offers business intelligence dashboards that can connect directly to data sources without manual file handling. Claude can also help document the query steps, review M Code, and identify why a new report no longer matches the expected structure.

Frequently asked questions

How do I set up Power Query to automatically use the latest file from a folder?

Create a source query in Power Query that connects to the folder where your reports are saved. Sort the files by their date modified, keep the top row, and then apply your transformation steps to the data from that file.

Can I use Power Query without constantly changing the source file?

Yes, you can use a folder connection to identify and pull in the newest file automatically each day. This way, you only need to refresh the queries without manually changing the source file every time.

What if my reports have different formats each day?

If the report structure changes, it can cause your query to fail. It's essential to maintain a consistent schema in your reports or implement validation steps to check for required columns before loading the data.

Extract Numbers from Text with VALUE in Excel

A formula can extract the number from entries such as 10ft or 100 pairs, but the most reliable solution is to keep the numeric value and the unit in separate columns. This prevents calculation errors and makes inventory reports easier to filter, sort and automate.

The problem

This issue came up in the r/excel community when someone was calculating price per item for inventory. A formula such as =A1/B1 works when A1 contains a price and B1 contains a number, such as a $10 pack divided into 5 items. The result is $2 per item.

The problem starts when the quantity cell contains both a number and text, such as 10ft or 100 pairs. Excel treats those entries as text, not as numeric cell values. A division formula cannot use them directly, so it returns an error.

The original discussion is available in the r/excel question about ignoring letters in cells.

Microsoft explains that numbers stored as text can produce unexpected formula results. Its recommended VALUE function can convert text that contains a valid number into a numeric value, but it does not solve every mixed entry that includes units.

The solution

Restructure the inventory table so the number and unit are stored separately:

Product	Pack price	Quantity	Unit	Price per unit
Cable	10	10	ft	1
Gloves	10	100	pairs	0.10

With the price in B2 and the quantity in C2, use:

=B2/C2

B2 is the pack price. The division operator / divides that price by the numeric quantity in C2. The result is the price per unit.

This is better than asking a formula to ignore letters because the workbook keeps data in a usable structure. You can calculate, sort, filter and summarize the quantity without cleaning the cell first.

You can still show the unit beside the quantity. Put ft, pairs, kg or another label in the Unit column. This also handles products with different measurement types without hiding information inside a text string.

If the unit must appear in the same cell for printing or presentation, use custom number formatting instead of typing the unit into the value. For example, a numeric cell containing 10 can display as 10 ft while remaining a number for calculations. In desktop Excel, select the cells, open Format Cells, choose Custom, and add the unit in quotation marks, such as:

0 "ft"

The 0 displays the numeric value. The text in quotation marks displays ft. Custom number formats change how a value looks without changing the underlying number. Microsoft notes that custom formats cannot be created directly in Excel for the web, so use the desktop application for this setup.

How to apply it

1. Make a copy of the inventory workbook before changing the structure.

2. Add a Quantity column beside the current column that contains entries such as 10ft or 100 pairs.

3. Add a Unit column next to Quantity.

4. Enter only the numeric portion in Quantity. Enter 10 instead of 10ft, and 100 instead of 100 pairs.

5. Enter the measurement in Unit. Use ft for feet and pairs for pairs.

6. Move the price into its own numeric column if it currently includes a currency symbol as text. A value such as 10 can still display as currency through number formatting.

7. Replace the old calculation with =B2/C2, adjusting the column references to match your workbook.

8. Fill the formula down the table by dragging the fill handle or copying the formula to the remaining rows.

9. Format the result as currency or as a number with the required decimal places.

10. If the unit must be visible inside the quantity cell, select the numeric Quantity cells and open Format Cells.

11. Choose Custom and enter a format such as 0 "ft" for feet or 0 "pairs" for pairs.

12. Test several products before deleting the old column. Include whole numbers, decimals, zero quantities and blank rows.

For an existing workbook that already contains mixed text, use a temporary cleanup column rather than manually editing every row. Microsoft recommends VALUE for text that represents a valid number, using a formula such as =VALUE(E2). This works when E2 contains numeric text, but entries such as 10ft may need a separate cleaning step because the unit is attached to the number.

A formula that extracts digits from arbitrary text can be built, but it is usually less robust for inventory. It may mishandle decimals, negative values, thousands separators or entries containing more than one number. Separating the fields avoids those risks.

If different rows use different units, do not convert them into one total unless the measurements are genuinely comparable. Ten feet, ten meters and ten pairs are different quantities. Keeping the unit in a separate column makes that difference visible.

Implementation angle

For a small inventory, separate Quantity and Unit columns provide a clean foundation for importing products into Zoho Creator or another database-style application. An automation in Make or n8n can validate that Quantity is numeric, check that Unit is present, and calculate price per unit before sending the record to accounting or reporting tools. Claude can also help review the workbook for mixed text values and generate cleanup formulas, but the final structure should keep numbers and labels separate.

For businesses managing larger inventories with multiple warehouses or stock locations, Zoho Inventory offers multi-warehouse tracking and automated reorder points that work seamlessly with properly structured data. When your spreadsheet outgrows manual management, structured data entry forms can enforce the separation of quantity and unit fields at the point of entry, preventing mixed-format errors before they occur.

Frequently asked questions

How can I separate numbers and units in Excel?

You can create separate columns for the numeric value and the unit in your Excel sheet. For example, have one column for quantity and another for the unit label like "ft" or "pairs." This method prevents calculation errors and makes your data easier to work with.

What happens if my quantity cell contains text?

When your quantity cell includes both numbers and text, like "10ft," Excel treats it as text instead of a numeric value. This can cause errors in formulas that expect numeric inputs, such as division. To fix this, you should store the number and the unit in different columns.

Can I format a cell to display units without changing the underlying value?

Yes, you can use custom number formatting in Excel to display units next to a numeric value. For instance, you can format a cell to show "10 ft" while keeping it as a number for calculations. This is done by selecting the cell, choosing Custom format, and adding your unit in quotation marks.
