About XML Formatter
XML parsing and formatting.
XML parsing and formatting runs locally in the browser for quick developer workflows. Verify important output in the target application. The formatter parses the XML into a document tree and re-serializes it with consistent indentation, which also validates well-formedness as a side effect. Unlike regex-based "formatters," it cannot produce invalid XML from valid input. Structured data tools depend on valid syntax, encoding rules, delimiters and the expected target format. Validate the result against the format or application that will consume it and keep the original input.
Primary objective: XML parsing and formatting locally in the browser.
Privacy assurance: Parsing and transformation are performed locally in the browser from the data you enter.

Frequently Asked Questions
What is XML parsing and formatting used for?
It provides a focused browser workflow for xml parsing and formatting.
Is my data uploaded?
The workflow is designed to process the entered data locally in the browser.
Should I verify the result?
Yes. Test important output in the target environment.
Will formatting change my data?
No. It changes whitespace between elements only. Text content, attributes, and comments are preserved byte-for-byte.
What if my XML has an error?
The parser reports the exact line and column of the first well-formedness error — mismatched tags, unescaped ampersands, and bad declarations are the usual suspects.
Does it handle namespaces?
Yes — namespace prefixes and declarations are preserved exactly as authored.
