Your data never leaves this browser

A client-side alternative to online converters

Converters that run in the cloud are convenient until the file is sensitive. This tool keeps the convenience and removes the upload: everything runs locally, from parsing to export.

You can prove it too. Load the page, disconnect your network, and the conversion still works — a clear sign that no server is involved.

Frequently asked questions

How do I know it is really local?
Open the Verify Security panel and run the self-check; it counts the network requests made while converting 1,000 local rows.
Which formats are supported?
CSV, TSV, TXT, JSON, XLSX, and XLS going in; SQL, CSV, Markdown, and formatted JSON coming out.
Is there a catch with the free version?
Guests process up to 500 rows per file; a free account raises that to 50,000. No payment is required.
Is my data cached for offline use?
Only the site's own static assets are cached. Your files and results are not stored.
