How is this different from a normal converter?

There is no upload step. The file is read and processed in your browser, so your data never transits the network.

Can I prove nothing is uploaded?

Yes. Open the Verify Security panel, run the self-check, and watch the request count stay at zero.

Which formats can I bring?

CSV, TSV, TXT, JSON, XLSX, and XLS, up to 100MB.

SQL INSERT statements, CSV, Markdown, and formatted JSON.

Convert data without uploading to a server

Most online converters ask you to upload a file first. This one inverts that: parsing, cleaning, and conversion all happen on your device, and the site has no place to store your rows even if it wanted to.

Bring CSV, Excel, JSON, or TSV. Choose whether you need SQL, CSV, Markdown, or formatted JSON. The whole flow is the same, and none of it touches a server.
