How to delete every other row in excel

Answer

Deleting every other row removes rows in a repeating pattern. A user does this to clean large datasets, improve readability, or prepare structured data for analysis.

To delete every other row in Excel, follow a structured method that works reliably on Windows and Mac. The core steps use a helper column, sorting, and bulk deletion. This method maintains data accuracy across large spreadsheets.

Method 1: Use a helper column and filter

1.      Enter a number in the first cell of a new helper column next to your data. Example: type 1 in the first row where your data begins.

2.      Enter 2 in the next row.

3.      Select those two cells.

4.      Drag the fill handle down to repeat the 1,2,1,2 pattern for the whole dataset.

5.      Select the helper column.

6.      Open the Data tab on the Ribbon.

7.      Select Filter.

8.      Click the filter arrow on the helper column.

9.      Choose the number you want to delete. Choose 2 when you want every second row deleted.

10.  Highlight all visible filtered rows by selecting them.

11.  Press Ctrl + – on Windows or Command + – on Mac to delete the visible rows.

12.  Remove the filter.

13.  Delete the helper column.

Method 2: Use a formula-driven pattern

This method creates the alternating pattern without manual entries.

1.      Insert a new column next to your data.

2.      Enter the formula =MOD(ROW(),2) in the first cell of this column.

3.      Press Enter.

4.      Fill the formula down for the entire dataset.

5.      Filter the new column.

6.      Keep the rows where the value is 1 or 0, depending on which set you want removed.

7.      Select the visible filtered rows.

8.      Press Ctrl + – on Windows or Command + – on Mac.

9.      Remove the filter.

10.  Delete the helper column.

Method 3: Use Go To Special

This method works when the pattern begins at the first data row.

1.      Select the range of rows you want to clean.

2.      Open Home > Find & Select > Go To Special.

3.      Choose Blanks when every other row is empty.

4.      Press Ctrl + – on Windows or Command + – on Mac.

5.      Confirm Entire Row.

This method works only when a row contains blank cells in a predictable pattern.

Why does Excel require a helper structure?

Excel treats rows as independent records. Deletion of every other row requires a pattern that Excel can identify and filter. Helper structures create this pattern. The dataset remains intact during deletion until the user confirms the final removal.

Does this affect formulas?

Yes. Formulas referencing deleted rows return errors or adjust to the nearest valid reference. A user maintains formula integrity by converting formulas to values before deletion, where needed.

Conclusion

Deleting every other row improves dataset usability. A helper column provides the most accurate control across all Excel versions. The methods above follow structured data-cleaning practices and remain consistent with credible documentation from Excel support channels.
