What if you could transform tedious row selection in Excel from a manual chore into a strategic advantage for your business? In today's data-driven landscape, efficiency isn't just a productivity metric—it's a competitive differentiator. The way you manipulate and filter your datasets can either bog down decision-making or accelerate it. So, how can you leverage Excel's built-in intelligence to elevate your spreadsheet operations and drive smarter outcomes?
Business leaders are constantly challenged to extract meaningful insights from sprawling datasets. Whether you're analyzing customer segments, financial transactions, or operational logs, the ability to rapidly filter and highlight relevant data is critical. Traditional manual selection of odd rows is not only time-consuming but also prone to error—especially as data volumes grow. This is where Excel's formula-driven automation becomes a strategic enabler.
Enter the ISODD formula—a deceptively simple yet powerful Excel function that can instantly distinguish odd rows from even rows within your dataset. By pairing the ISODD function with the ROW() function in a helper column, you create a dynamic Boolean marker:
=ISODD(ROW())
This formula returns TRUE for odd rows and FALSE for even rows, providing a logical basis for advanced row selection, filtering, and conditional formatting[2][3][4][5]. Once applied, you can use Excel's Filter feature or Conditional Formatting to highlight or select only those rows where the value is TRUE—streamlining your workflow and minimizing manual intervention[3][5].
Why does this matter beyond convenience? Automating row selection with ISODD and ROW() isn't just an Excel tip—it's a microcosm of digital transformation. You're shifting from manual data manipulation to formula-driven automation, freeing up time for higher-value analysis and enabling repeatable, error-free processes. This approach also lays the groundwork for further automation, such as integrating with n8n workflow automation, automating reports, or setting up dynamic dashboards that react to real-time data changes.
Consider the broader implications:
- Pattern Analysis: Use ISODD to alternate row colors for improved readability, or to segment data for targeted analysis[4].
- Scalability: As your datasets grow, formula-driven selection ensures your processes remain robust—no matter the volume.
- Data Integrity: Reduce the risk of human error and ensure consistency in reporting and analytics.
Imagine a future where every repetitive spreadsheet operation is automated, allowing you and your team to focus on strategic insights rather than manual tasks. The ISODD formula is a small but potent example of how Excel's functions can drive business transformation—turning raw data into actionable intelligence with minimal effort.

If a single formula can eliminate hours of manual work, what other hidden efficiencies are waiting to be unlocked in your organization's digital toolkit? Perhaps it's time to explore comprehensive automation strategies that extend far beyond Excel into your entire business ecosystem.
What does =ISODD(ROW()) do?
The formula =ISODD(ROW()) returns TRUE for odd-numbered worksheet rows and FALSE for even-numbered rows. ROW() returns the current row number; ISODD() tests whether that number is odd, producing a Boolean marker you can use for filtering, conditional formatting, or formulas. This technique is particularly useful when you need to automate data processing workflows that require alternating row selection.
How do I add a helper column to select only odd rows?
Insert a new column next to your data. In the first data row (e.g., row 2 if row 1 is a header), enter =ISODD(ROW()) and drag or double-click the fill handle to copy down. Turn on Filter for your header row and filter that helper column to show only TRUE values—this displays only odd rows. For more advanced data manipulation techniques, consider using Zoho Creator which offers powerful database filtering capabilities without complex formulas.
How can I highlight odd rows using Conditional Formatting?
Select the range you want to format, open Conditional Formatting → New Rule → Use a formula to determine which cells to format, and enter =ISODD(ROW()). Choose your formatting (fill color, etc.) and apply. The rule will color every odd worksheet row in the selected range. This visual approach works well for data presentation and analysis, making patterns more apparent to stakeholders.
How do I select even rows instead of odd rows?
Use =NOT(ISODD(ROW())) or =ISEVEN(ROW()) in your helper column or conditional formatting rule. Both approaches return TRUE for even rows. When working with larger datasets that require more sophisticated filtering, Zoho Analytics provides advanced data manipulation tools that can handle complex row selection criteria automatically.
Will these formulas stay correct if I insert or delete rows?
Yes. Because ROW() reads the sheet's row numbers, inserted or deleted rows automatically change the row numbers and the ISODD/ISEVEN result updates dynamically. If you use an Excel Table, a calculated column will auto-fill new rows as they're added. For businesses requiring robust data integrity across multiple users, consider implementing proper internal controls to ensure data consistency during collaborative editing.
Can I copy or extract only the filtered (visible) rows after applying the helper column?
Yes. After filtering, select the visible range and copy. To avoid copying hidden cells, use Home → Find & Select → Go To Special → Visible cells only (or press Alt+;), then paste where needed. For automated data extraction and processing, Make.com can streamline these workflows by automatically handling filtered data exports and integrating them with other business systems.
Is there an alternative formula to ISODD for selecting every other row?
Yes. You can use =MOD(ROW(),2)=1 to mark odd rows or =MOD(ROW(),2)=0 for even rows. MOD is useful if you want to generalize (for example, MOD(ROW(),3)=1 to pick every third row). This mathematical approach provides more flexibility for complex sampling patterns, which becomes especially valuable when implementing statistical analysis workflows that require specific data sampling methodologies.
Will using conditional formatting or helper columns slow down large workbooks?
Conditional formatting across very large ranges can impact performance. Helper columns with simple formulas like ISODD(ROW()) are lightweight and generally faster. For very large datasets, convert your data to an Excel Table (which auto-fills formulas) or filter based on the helper column before further processing to improve responsiveness. When dealing with enterprise-scale data, consider migrating to cloud-based solutions that can handle massive datasets more efficiently.
How does this technique fit into broader automation workflows?
The Boolean marker (TRUE/FALSE) created by ISODD(ROW()) is easy for automation tools to consume. You can filter/export only TRUE rows and feed them to automation platforms (Make, n8n, Power Automate) or use Office Scripts / VBA to programmatically act on those rows—enabling repeatable, error-free processes and downstream integrations. For comprehensive automation strategies, explore n8n which excels at connecting spreadsheet data with complex business workflows.
Does ISODD(ROW()) work across Excel versions and Excel Online?
ISODD and ROW are standard worksheet functions available in modern Excel for Windows, Mac, and Excel Online. If you experience an error, check workbook calculation settings (should be Automatic) and ensure function names match your locale (some language versions use different localized function names). For teams working across different platforms and versions, implementing proper data governance ensures consistency regardless of the tools being used.
How do I handle header rows so they aren't marked as odd or even data?
Start your helper-formula in the first data row (beneath the header). If your header is row 1, place =ISODD(ROW()) in row 2 and fill downward. Alternatively, exclude the header from your conditional formatting range or filter criteria so headers remain unaffected. This approach maintains data integrity while preserving the visual structure that's essential for effective data presentation to stakeholders.
Can I sample every Nth row (not just every other row)?
Yes. Use MOD to generalize: =MOD(ROW()-START, N)=0 where START is the row offset (for example, START=2 if your data starts on row 2) and N is the step. This returns TRUE for every Nth row starting at your chosen offset. This sampling technique is particularly valuable for statistical analysis and machine learning applications where you need representative data samples from larger datasets.
Any practical tips for making this technique production-ready?
Use a clearly labeled helper column, convert your dataset to an Excel Table so formulas auto-fill, keep formulas simple (ISODD/ISEVEN/MOD), and document the purpose of the helper column. When automating, export filtered data (CSV or via API) rather than relying on screen-scraping, and test with insert/delete row scenarios to confirm behavior. For enterprise implementations, consider adopting compliance frameworks that ensure your data processing methods meet regulatory requirements.
