Convert JSON files to XML free in your browser — no signup, no install, and the file is never uploaded to a server. XML keeps full quality with no further loss.
Add your JSON file
Drag the JSON file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm XML as the output
XML is already selected as the output format on this page. This format converts straight through with no extra settings.
Run the conversion
Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.
Download the XML file
When it finishes, download the XML file. Converting multiple files gives you the option to download them together as a ZIP.
The de facto standard for exchanging data through web APIs. It is human-readable while remaining easy for programs to parse.
A general-purpose markup language that expresses structure through tags. Its support for strict schema validation makes it common in enterprise systems and public data exchange.
Yes. JSON to XML conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the JSON file never leaves your device. That is also why it works without an internet connection once the page has loaded.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
