Everything You Need to Know
Learn why thousands of analysts and teams trust CleanCSV.
Is CleanCSV really 100% free with no hidden limits? ↓
Yes! CleanCSV is 100% free with zero paywalls, zero subscriptions, and zero limits. While competitors like DataSort cap free users at 500 rows and CleanMyExcel restricts uploads to 1MB, CleanCSV lets you clean large datasets up to 64MB without paying a cent.
Do I need to enter an email address to download my cleaned data? ↓
Never. Unlike CleanMyExcel which holds your file hostage behind an email form, CleanCSV gives you instant 1-click downloads directly in your browser. Download in CSV, Excel (.xlsx), or JSON instantly.
Can I edit cells directly before exporting? ↓
Yes. CleanCSV features an Excel-like interactive spreadsheet grid. You can double click any cell to edit it, use the "⚠️ Issues Only" filter to pinpoint flawed rows, and export your exact edits in real-time.
How is my data kept safe and private? ↓
CleanCSV processes all uploaded files in-memory using stateless Python & Pandas engines. Files are never stored in a database or retained on our server. As soon as your download completes, the memory buffer is cleared.
How does the AI fuzzy duplicate clustering work? ↓
Standard tools only remove exact row duplicates. CleanCSV's AI fuzzy clustering analyzes text similarity across category columns (e.g. matching "United States", "USA", "United States of America") to eliminate near-duplicates and standardize variations.
Can I batch clean multiple CSV and Excel files at once? ↓
Yes! Simply drag and drop or select multiple files in the upload box. CleanCSV will process all files in parallel and download a neat ZIP archive containing every cleaned CSV or Excel file.
