Remove unwanted columns from CSV files online for free. Select which columns to keep or delete. No software needed.
Use This Tool Free — No SignupCSV exports often include far more columns than you actually need. Database exports, CRM downloads, analytics reports, and system data dumps frequently contain dozens of columns when you only need a handful. Our free column remover lets you quickly strip out the columns you do not need, giving you a clean CSV with just the data you want. Upload your CSV, and the tool displays all columns with checkboxes. Simply uncheck the columns you want to remove — or check only the ones you want to keep. The tool previews the result so you can verify you are keeping the right data before downloading. This is dramatically faster than manually deleting columns in a spreadsheet, especially for large files with many columns. The tool handles CSVs of any size and preserves your data integrity throughout the process.
