Frequently asked questions

Which formats can I convert?

CSV, TSV, JSON, Excel (.xlsx), XML and YAML — in any direction. Paste data or open a file, choose the output format and download the result.

Is my data uploaded anywhere?

No. FileCrafty converts the data inside your browser, so customer lists, exports and API keys never leave your device. It also works offline once the page is open.

Is there a size limit?

There is no fixed limit — files of tens of megabytes work fine on a computer. Very large files are not shown in the text box, but they are still converted in full.

Is it free?

Yes — free, unlimited and without sign-up.
