About this tool
XML is still the wire format for a large share of financial and enterprise integrations, and those payloads tend to arrive as one enormous line. This tool re-indents the document so the structure is visible, and flags well-formedness problems — unclosed tags, mismatched names, stray characters — before you spend time hunting them by eye.
Validation uses the browser's built-in DOM parser. It checks well-formedness, not conformance to a schema, so a document can pass here and still be rejected by an XSD.
How to use it
- 1Paste your XML document into the input panel.
- 2Pick an indentation width, or minify to strip formatting whitespace.
- 3Copy the result, or fix the position the error message reports.
Privacy
This tool runs entirely in your browser. Nothing you type or paste is sent to a server, and your local history is stored only on this device.
