Remove Sensitive Columns
Remove password, salary or personal data columns before sharing files with others.
Clean Before ERP Import
Remove extra columns that cause mapping errors during SAP, Oracle or CRM import.
Reduce File Size
Remove unused columns to make files smaller and faster to process.

Frequently Asked Questions
Can I remove multiple columns at once?
Yes. Enter multiple column names separated by commas — for example "Email, Phone, Address" — and all three columns will be removed in one operation.
Is column name matching case sensitive?
No. Column matching is case insensitive — "email", "Email" and "EMAIL" all match the same column.
What file formats are supported?
CSV (.csv), Excel (.xlsx) and Excel 97-2003 (.xls) files are supported. The output is downloaded as a CSV file.
Is my file safe?
Yes. Files are processed temporarily and deleted immediately after download. We never store your data.
