JSON to XML converter
Your JSON goes in and an XML comes out. XML is the usual choice for RSS and Atom feeds, and sitemap files for search engines. Your file never leaves your computer.

How to convert JSON to XML
- 1 Drop your JSON .json file onto the page, or click to browse for it.
- 2 Check the options. Nothing is thrown away on the way to XML, so there is no quality dial to set.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the XML, or add more files and do the whole set in one go.
Why convert JSON to XML
- Schemas allow a document to be validated before it is processed.
- Namespaces let independent vocabularies be mixed in one document.
- RSS and Atom feeds, and sitemap files for search engines.
- JSON: no comments, so configuration files cannot be annotated.
JSON compared with XML
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | JSON | XML |
|---|---|---|
| File extension | .json | .xml |
| Colour depth | UTF-8 text, six value types, no comments or trailing commas | Unicode element tree with namespaces, DTD or XSD validation |
| Introduced | 2001 | 1998 |
| Developed by | Douglas Crockford | W3C |
Quality and what changes
Both sides are lossless, so every pixel survives the trip intact and converting back returns the same image. What changes is the size and what the file can carry: XML stores the data without compression, so expect a much larger file.
- One XML limitation to keep in mind: very verbose, with every element name repeated in its closing tag.
Questions about JSON to XML
Is my JSON file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your JSON is read straight from your own disk, converted on your machine and handed back as an XML. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several JSON files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate XML downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
