Two sides of the same conversion. JSON → XML takes a JSON object and builds an XML document from it; XML → JSON does the reverse, parsing an XML document into a JSON object. Together they let you move data between the two most common structured formats on the web — both run 100% locally.
Use JSON → XML when
- You have JSON data that needs to become an XML feed, an SVG, or a SOAP payload.
- You're working with an API that expects XML instead of JSON.
- You want to generate structured documents programmatically.
Use XML → JSON when
- You have an XML response (RSS, sitemap, SOAP) and want to work with it as JSON.
- You need to extract data from an XML document quickly.
- You're migrating from XML to JSON and need a parse step.
Side by side
| JSON → XML | XML → JSON | |
|---|---|---|
| Direction | JSON → XML | XML → JSON |
| Input | JSON | XML |
| Output | XML | JSON |
| Handles attributes? | Yes (configurable) | Yes – prefixed with @ |
| Preserves order? | Yes (arrays maintain order) | Yes (child order preserved) |
| Runs 100% locally | Yes | Yes |
Both conversions are lossless in their own direction. JSON → XML will respect your array order and typed values; XML → JSON will preserve attributes and element order. The reverse of a round‑trip may not be identical if you toggle options (like attributes or array preservation), but the core data remains intact.
Use JSON → XML when you're generating data for a legacy system; use XML → JSON when you're receiving data from one. They're perfect mirrors, and you'll often use them together in a pipeline.
