Frequently asked questions

What is a JSON file?

JSON is the most common data format for APIs, configuration files and web apps. JSON is what APIs, JavaScript and almost every programming language read natively.

What can I convert JSON files to?

YAML, TOML, XML, CSV, TSV, NDJSON, Excel, ODS. Pick a target after adding your files.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device, so it is safe for private photos, contracts and business data. Once the page has loaded it even works offline.

Is it free? Are there limits?

It is free, with no sign-up, no watermark and no daily limits. Because nothing is uploaded there is no upload size limit either; the only limit is your device’s memory, which matters mostly for very large videos.
