JSON to XML Converter

Convert JSON to XML and XML back to JSON in your browser. Two-way, pretty-printed, and your data never leaves your device.

Runs in your browser — nothing uploaded

Conversion happens in your browser — nothing is uploaded. Repeated XML tags become a JSON array; XML attributes are not carried over.

Convert JSON to XML and XML back to JSON in one place. Paste your data, pick a direction, and get clean, indented output you can copy straight into a config file or API payload. Both conversions run entirely in your browser.

Private by design — your data never leaves your device

How to use it

No account, no upload — it all happens on your device.

1
Pick the direction: JSON → XML or XML → JSON.
2
Paste your data into the input box.
3
Click Convert to generate pretty-printed output.
4
Copy the result to your clipboard.

How the two formats map

Objects, arrays, and values in each direction.

  • Objects → elements. Each JSON key becomes a nested XML element; the root is wrapped in <root>.
  • Arrays → repeated tags. A JSON array turns into several elements sharing one tag name.
  • Values → text. Strings, numbers, and booleans become the text inside an element and are re-typed on the way back to JSON.

Well-formed input matters

The converter uses strict parsers. Invalid JSON (trailing commas, single quotes) or malformed XML (unclosed tags, stray &) is reported with a clear message so you can fix the exact problem and try again.

Frequently asked

Is my data uploaded during conversion?
No. Both JSON→XML and XML→JSON run entirely in your browser using its built-in JSON and XML parsers. Nothing you paste is ever sent to a server.
How are arrays and repeated tags handled?
Going to XML, each item in a JSON array is emitted as a repeated element with the same tag name. Coming back to JSON, tags that appear more than once under the same parent are collected into an array.
Are XML attributes supported?
This converter focuses on element structure and text content, so XML attributes are not carried across. If you need attributes preserved, keep them as child elements instead.
