A private alternative to online CSV converters
There are plenty of CSV tools online, and almost all of them share one design choice: your file is uploaded to their server for processing. For a marketing list or a payroll export, that is an unnecessary risk.
PrivateDataForge flips the model. The CSV is parsed, cleaned, and exported by code already running in your browser, so the rows never cross the network.
Markdown / CSV Output
Drop a file to clean and export it
Processing stays in this browser. Guests can process up to 500 rows per file.

Frequently asked questions
- Can it clean the CSV, not just convert it?
- Yes. Trim whitespace, remove empty rows, remove duplicates, and normalize headers — with a live count of what was removed.
- What can I export?
- Cleaned CSV, a Markdown table, or SQL INSERT statements.
- Do I need an account?
- No. An account is optional and only raises the row limit and remembers preferences.
- Does it work with large files?
- Files up to 100MB open, and parsing runs in a Web Worker so the page stays responsive.
