About DataFmt

DataFmt is a focused suite of free online tools for converting between structured data formats. Our mission is to let developers and data practitioners perform these routine transformations as quickly and safely as possible.

We believe privacy is table-stakes for a utility like this, so DataFmt never adopts an upload-process-download server model. All computation happens in your browser, from input to output.

The current release covers CSV ⇄ JSON and CSV ⇄ Markdown tables, with a dedicated page for each direction containing a full guide and FAQ. Additional formats such as YAML, XML and TSV are on the roadmap.
