Guide

1
Paste or upload source data
Add JSON in the left panel or XML in the right panel. You can also upload matching files when you already have exports from an API, SOAP service, or config pipeline.
2
Adjust output settings
Pick JSON spacing, XML indent size, a root element name for top-level arrays, and whether the XML output should include the standard declaration line.
3
Run the conversion
Click JSON → XML or XML → JSON. The opposite panel fills with formatted output you can review before copying or downloading.
4
Copy or export
Use Copy or Download on either output area to grab converted.json or converted.xml for scripts, tests, or documentation.

Use @_ keys in JSON when you need XML attributes to round-trip cleanly.
Top-level JSON arrays are wrapped in the root element name you choose.
Keep XML well-formed — unclosed tags or invalid characters will fail conversion.
For large payloads, convert in chunks to make manual cleanup easier if needed.

GuideConvert JSON and XML in three steps3 steps

Add JSON or XML in either panel, or upload a .json or .xml file to load it into the workspace.

Choose JSON spacing, XML indent depth, root element name, and whether to include an XML declaration.

Run JSON → XML or XML → JSON, then copy the output or download it as a ready-to-use file.

FAQJSON and XML conversion questions

No. Conversion runs entirely in your browser. Your JSON and XML never leave your device unless you choose to download or copy the result.

Attributes are converted to JSON keys prefixed with @_ so they stay distinct from child elements during round-trip conversion.

Yes. Use the XML panel and click Convert to JSON for a round-trip workflow between API and config formats.
