FAQ
Is this really free?
Yes — no sign-up, no paywall, no row limit. Everything works for free.
Is my data safe?
The file never leaves your browser tab — it's processed locally by JavaScript and WASM. To check: open DevTools → Network, drop a file, and process it. You'll see no requests carrying file data.
Are there any limits?
No row limit. Files up to about 100 MB work fine. Above that it depends on how much RAM your browser has.
What file formats are supported?
You can drop in .csv, .tsv, or .txt. You can download as CSV, Excel (.xlsx), or JSON.
