Is my CSV data secure when using CSVClean?

Yes, absolutely. All CSV processing happens entirely in your browser using JavaScript. Your files never leave your device, and we have zero access to your data. Nothing is uploaded to our servers.

Do you store my CSV files?

No. We never store, log, or have any access to your CSV files. All processing is done locally in your browser, and data is automatically cleared from memory when you close the page.

How does CSVClean pricing work?

Free users can process CSV files up to 5,000 rows with basic features. Pro users ($10/month) can process up to 100,000 rows per file and access advanced features like duplicate removal, date standardization, and number formatting.

What file formats does CSVClean support?

We currently support CSV (Comma Separated Values) files. Your cleaned file will be exported as a CSV that you can open in Excel, Google Sheets, or any spreadsheet application.

Do I need to create an account to use CSVClean?

No account needed for basic use! You can clean CSV files up to 5,000 rows without signing in. An account is only required if you want to upgrade to Pro for larger files and advanced features.

What if a column has just one value?

If any row in a column has data, the entire column is kept. Only columns that are completely empty across all rows are removed.

Will my column headers be affected?

If a column has a header but no data in any row below it, the entire column (including the header) will be removed.

Can I preview which columns will be removed?

Yes. After processing, you'll see exactly how many columns were removed and can preview your cleaned data before downloading.
