About This Tool
Free, private, in-browser XML formatter and minifier. Beautify with 2 or 4 spaces, minify payloads, inspect tag counts, and validate syntax with zero latency and 100% privacy.
How to Use
- Paste XML Payload: Insert your unformatted XML code, SOAP envelope, or SVG vector markup into the input editor.
- Select Indentation Style: Choose between 2 spaces, 4 spaces, or tabs for customized code formatting.
- Format or Compress: Click Beautify to pretty-print with hierarchical indentation, or Minify to strip all extraneous whitespace.
- Review Metrics & Copy: Inspect structural tag counts, size reduction stats, and copy the formatted output instantly to your clipboard.
Frequently Asked Questions
What is the difference between Beautifying and Minifying XML?
Beautifying (pretty-printing) reformats unorganized XML by adding standardized line breaks and hierarchical indentation (e.g., 2 or 4 spaces per depth level), making the document human-readable and easy to audit. Minifying strips all non-essential inter-element whitespace, tabs, and carriage returns, minimizing the payload byte size for network transmission without altering the data structure.
How does the formatter handle CDATA sections?
CDATA (<![CDATA[ ... ]]>) blocks contain raw character data that must be preserved verbatim. Our formatter protects CDATA contents from whitespace alterations, ensuring that embedded scripts, binary payloads, or pre-formatted text remain completely uncorrupted.
Does this tool validate XML schemas (XSD / DTD)?
The tool verifies structural well-formedness according to W3C XML 1.0 specifications—confirming matching tags, quoted attributes, escaped entities, and a single root element. It does not evaluate semantic schema validity against external XSD or DTD files, ensuring instant in-browser execution with zero network latency.
What causes the 'XML Parsing Error: not well-formed' message?
This error occurs when an XML document violates fundamental syntax rules. Common triggers include missing closing tags, case mismatches between start and end tags, unquoted attribute values, unescaped ampersands (&), or multiple root-level elements.
Can minifying XML break my application?
In standard XML documents, inter-element whitespace between tags is considered insignificant and can be safely removed. However, if your application enforces xml:space='preserve' or processes mixed-content text nodes where whitespace carries semantic meaning, minification should be validated against your specific parser.
Is my proprietary XML data sent to any third-party server?
No. All XML parsing, beautification, minification, and statistics calculation occur exclusively inside your web browser sandbox. No text, tokens, or files are ever transmitted across external networks, guaranteeing 100% confidentiality.
What indentation style is recommended for enterprise XML?
For web technologies, Android layouts, and SVG vector files, 2 spaces is the dominant industry standard due to its compact horizontal width. For enterprise Java configurations (such as Maven pom.xml, Spring schemas, and SOAP envelopes), 4 spaces is traditionally preferred for enhanced visual depth.
How can I convert formatted XML into a JSON payload?
You can format your XML here to verify its structural integrity, then copy the result directly into our companion XML to JSON Converter, which automatically translates XML element hierarchies into JSON arrays and objects.
