Deleting every other line in Excel is a common data management task that helps streamline large datasets for better analysis and readability.
While Excel requires specific functions and manual steps to accomplish this task, modern solutions offer more efficient approaches.
We'll explore how Sourcetable, an AI-powered spreadsheet platform, lets you analyze data and perform tasks like this simply by chatting with an AI assistant - try Sourcetable now to transform how you work with spreadsheets.
To delete every other line in Excel, users have multiple methods at their disposal, such as filtering or VBA scripting, suitable for different dataset sizes and user proficiency levels.
Begin by applying a filter to alternate rows in your Excel spreadsheet. This can be done manually or by using the formula =MOD(ROW(),2)
to generate a sequence of zeros and ones and filtering based on that sequence. Select the alternate rows based on the filter results. Before deletion, consider copying rows to preserve data. To delete, choose the 'Delete Row' command.
For automation, leverage VBA with the Sub Delete_Alternate_Rows_Excel()
. Define the range with Set SourceRange = Application.Selection
. Use Application.InputBox
for range selection. Target the first cell with FirstCell = SourceRange.Cells(RowIndex, 1)
and delete using FirstCell.EntireRow.Delete
. Ensure to toggle Application.ScreenUpdating
to False before deletion and back to True afterward for performance optimization.
For enhanced efficiency, particularly with larger datasets, consider the formula =MOD(ROW()-m , n)
, which facilitates filtering every Nth row. This method requires defining the variables 'm' and 'n' for starting row offset and step increment respectively. Alter 'n' to 2 for deleting every other row.
If data retention is a priority, make a copy of the rows you plan to delete before executing the removal process. This can prevent accidental data loss.
Streamline Complex Datasets |
Remove unnecessary or redundant information from large datasets to make them more manageable. This technique helps focus on essential data points and reduces file size. |
Prepare Clean Reports |
When preparing data for reporting, eliminate alternate rows to create more readable and focused presentations. This is particularly useful when dealing with raw data that contains placeholder or intermediate calculation rows. |
Fix Systematic Import Errors |
Address data import issues where errors or inconsistencies appear in alternating lines. This commonly occurs when data is imported from legacy systems or poorly formatted source files. |
Enhance Visual Analysis |
Improve the visual clarity of data by reducing the density of information displayed. This makes patterns and trends more apparent and easier to identify at a glance. |
Create Data Samples |
Generate representative data samples for testing or analysis by systematically removing alternate lines. This provides a consistent method for creating smaller, manageable datasets while maintaining data distribution. |
While Excel is a traditional spreadsheet tool requiring manual data manipulation and function expertise, Sourcetable revolutionizes spreadsheet work with an AI-powered interface.

The filtering method is the simplest way. Create a helper column using the MOD function to return 0s and 1s, filter the rows you want to delete, and delete them all at once.
Use the formula =MOD(ROW(),2) in a helper column. This returns 0 for even rows and 1 for odd rows. Filter the helper column to show only 0s to delete even rows, or show only 1s to delete odd rows.
Use the formula =MOD(ROW()-m, n) in a helper column, where m is the row number of the first cell with data minus 1, and n is the Nth row you want to delete. Filter and delete the rows with your desired value.
