Remove Empty Columns from CSV
Delete columns with no data from your CSV or spreadsheet. Simplify your schema automatically.
What this tool does
Exported data often comes with dozens of empty columns cluttering your view. Tabular identifies columns with no meaningful data and removes them — giving you a cleaner, leaner dataset ready for analysis.
Problems it solves
- CRM exports with dozens of unpopulated fields
- Survey tools exporting every possible question
- Database exports with NULL-heavy columns
- Spreadsheets with placeholder columns
- API responses mapped to wide schemas
Example

Frequently asked questions
What counts as an empty column?
A column where every data row is empty or whitespace-only. The header is not considered when evaluating emptiness.
Can I keep columns with a few values?
Yes. Adjust the threshold to only remove columns where, say, 95% of rows are empty. This preserves sparsely populated columns you might need.
Is this free?
Yes. Remove empty columns is available on the free plan for files up to 5 MB.
Will the column order change?
No. The remaining columns stay in their original order.
Can I preview which columns will be removed?
Yes. The preview panel shows the resulting table before you download, and the summary lists which columns were removed.
