Online XML Formatter, Validator & XML to JSON Converter

Beautify unindented XML documents, validate syntax and tag closure, and convert bidirectionally between XML and JSON data structures.

Local Processing & Data Privacy

All formatting, parsing, decoding, and validation executes entirely within your browser using modern Web APIs and JavaScript. Your tokens, JSON payloads, regex inputs, and queries never leave your computer.

About this Tool

XML remains an essential format across enterprise SOAP APIs, RSS/Atom feeds, Android application manifests, SVG vectors, and legacy system integrations. However, minified or unindented XML payloads can be notoriously difficult to read or debug when tags mismatch.

DevRef's Online XML Tool automatically indents nested elements, validates XML syntax with DOMParser error reporting, and provides bidirectional transformation between XML documents and JSON objects. Everything runs in-browser—confidential XML documents and enterprise API payloads are never uploaded or stored.

How to Use

  1. 1Paste XML or JSON: Insert your XML snippet or JSON object into the input editor panel.
  2. 2Format & Validate: Click Format to indent tags with consistent 2-space or 4-space tab stops and verify schema validity.
  3. 3Convert to JSON: Click 'XML to JSON' to parse element attributes and child nodes into a structured JSON hierarchy.
  4. 4Copy Result: Copy the formatted XML or converted JSON directly to your clipboard or download as a file.

Key Features

  • •Intelligent XML tag indentation and attribute alignment
  • •Real-time syntax validation with detailed parse error line highlighting
  • •Bidirectional conversion between XML and standard JSON data structures
  • •Minify mode for stripping whitespace from production XML payloads
  • •100% client-side execution: enterprise schemas and private payloads never leave your computer

Frequently Asked Questions

How are XML attributes handled when converting to JSON?

Attributes are parsed with an '@' prefix (e.g., '@id' or '@class') to distinguish element attributes from child element nodes.

Can this tool handle self-closing tags and CDATA blocks?

Yes. Standard self-closing tags (<tag />) and <![CDATA[...]]> raw text blocks are preserved and handled accurately according to W3C XML specifications.

Is my XML data sent to any remote server?

No. All formatting, DOM parsing, and JSON conversion happens inside your browser using client-side JavaScript. No data is transmitted.
