FAQ
Is this really free?
Yes. No sign-up, no feature gates, no paywall at the moment. If we bring paid plans back later, they won't touch what's free today.
Is my data safe?
The file never leaves your browser tab — processing happens locally in JavaScript + WASM. Want to verify? Open DevTools → Network, drop a file, watch it process with zero outbound requests.
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.
