Frequently Asked Questions: XML to JSON

How do I convert XML to JSON online without uploading sensitive files? ▾

Paste your XML data or drag and drop a .xml file into the converter above. ZeroUpload parses XML and serializes JSON 100% inside your browser RAM using local JavaScript—no bytes are ever sent to an external server.

How are nested objects or tabular columns mapped between XML and JSON? ▾

When converting hierarchical structures (Tree of parent/child elements and attributes) and tabular or config formats (Deeply nested trees & arrays), our engine automatically flattens or unflattens dot-separated keys (such as address.city) and preserves numbers, booleans, arrays, and null values.

Is this XML to JSON converter free for commercial and production config files? ▾

Yes. The tool is completely free, requires no account or API key, and works offline once loaded. Because execution happens in local memory, it is safe for proprietary XML, database exports, and production secrets.

Can I convert JSON back to XML? ▾

Yes! Click the "Swap (JSON → XML)" button at the top of the workspace or use the reverse converter link at the bottom of this page for bidirectional conversion.
