No re-upload neededThese tools accept .JSON - your file is handed over directly.
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
XML is a widespread, hierarchical data format - typical for RSS feeds, SOAP APIs, Office documents, configs and data exchange between systems. For processing in modern programs and APIs, JSON is handier though. This tool translates the tree structure of XML into an equivalent JSON object.
This tool parses your XML entirely locally in your browser (fast-xml-parser, pure JavaScript). Nested elements become nested objects and attributes are kept with the "@_" prefix, so no information is lost. Invalid XML is rejected with a clear error. Nothing is uploaded.
You will meet this when evaluating a news feed, a sitemap, a bank-statement interface or an old data-export spec that still thinks in angle brackets. When reading the result, note one quirk: if a child element occurs only once, a single object arises, whereas on repetition a list does. Accounting for that in the consuming code avoids surprising edge cases when the count varies.

Limitations: The XML must be well-formed (otherwise a clear error). Attributes get the "@_" prefix. Number- and boolean-looking text is automatically recognised as real JSON numbers/booleans; a date stays text, since XML has no date format of its own. Comments and processing instructions are skipped. Mixed content (text alongside child elements) cannot always map unambiguously. Namespaces stay as a prefix in the key.
No. The conversion runs entirely locally in the browser - nothing is sent.
Yes. Attributes appear in the JSON with the "@_" prefix before the name.
You get a clear error message with the cause - no crash.
The output here is always neatly indented. For a compact (minified) version, pass the result through our Format JSON tool afterwards with the Compact option.
