XML to JSON Converter — Free Online Tool

How to use XML to JSON Converter

Convert XML to readable JSON directly in your browser. Preserve XML attributes as @-prefixed properties, group repeated sibling elements into arrays and validate malformed documents without uploading content.

1. Paste a well-formed XML document (maximum 100,000 characters).
2. Choose compact, two-space or four-space JSON formatting.
3. Convert and inspect nested elements, attributes and repeated items.
4. Copy the generated JSON; verify mixed-content and namespace handling before production use.

Important: Keep highly sensitive input out of untrusted browsers. XML input is size and nesting-limited.

Formula and methodology

Element mapping: attributes become @name keys; text becomes #text; children become nested properties; repeated sibling names become arrays. JSON keeps XML text values as strings, with whitespace normalized for readability.

The interactive calculations depend on the inputs, units and assumptions you provide. Display values are rounded for readability, but calculations use unrounded input values where applicable.

Worked example

An XML element `Blue` maps to `{ “item”: { “@sku”: “A1”, “name”: { “#text”: “Blue” } } }`. This is a readable mapping, not lossless XML round-tripping.

Try entering your own measurements above to reproduce this calculation and understand each result.
