Why use our XML Formatter?
Beautify or Minify
Pretty-print messy XML for reading or compress it to a single line for transport.
Instant Validation
Catch unclosed tags, bad nesting, and malformed declarations before they hit production.
Private Local Processing
Format SOAP envelopes, RSS feeds, and config files without uploading them.
What is an XML Formatter?
An XML formatter takes raw Extensible Markup Language documents and rewrites them with consistent indentation and line breaks — or minifies them by removing unnecessary whitespace. XML appears in SOAP APIs, RSS and Atom feeds, SVG graphics, Maven POM files, Android layouts, and enterprise configuration.
Our free online XML formatter beautifies and minifies markup in your browser. Paste a response from a legacy API, an RSS channel, or a Spring applicationContext file, then copy clean output for documentation, diffs, or deployment. Validation highlights structural problems so you fix syntax before parsers reject the file.
XML Formatter Capabilities
- Beautify:Add readable indentation and line breaks to dense single-line XML.
- Minify:Strip whitespace for smaller payloads in logs and HTTP bodies.
- SOAP support:Format envelopes, headers, and bodies for WSDL-based integrations.
- RSS & Atom:Pretty-print syndication feeds for debugging podcast and blog pipelines.
- SVG & configs:Inspect vector markup and application XML settings with clear structure.
- Validate structure:Surface parse errors for mismatched tags and invalid characters.
Common Use Cases
SOAP API Debugging
Readable envelopes make it easier to spot wrong namespaces and body elements.
RSS Feed Fixes
Format item blocks to find missing pubDate or enclosure URLs.
SVG Icon Editing
Expand path data across lines before tweaking attributes in design handoffs.
Enterprise Config Files
Beautify Spring, Maven, or IIS XML configs during migrations.
Log & Payload Review
Minify or expand XML fragments captured from proxies and message queues.
Documentation Examples
Produce clean samples for internal API guides and support articles.
How to Use the XML Formatter
Paste Your XML
Copy markup from a browser network tab, IDE, or log file into the input area.
Choose Beautify or Minify
Pick readable indentation for review or compact output for transmission.
Format & Validate
Run the formatter to rewrite the document and report structural errors.
Copy Clean Output
Use the result in tickets, repos, or API clients with confidence.
Benefits of Using an XML Formatter
Readable Legacy Integrations
Make dense SOAP and enterprise XML approachable for modern teams.
Faster Diff Reviews
Consistent indentation turns noisy one-liners into reviewable structures.
Smaller Wire Payloads
Minified XML saves bytes when size limits matter in logs or devices.
Early Error Detection
Find tag mismatches before deployment instead of at runtime parse failures.
No Desktop Tool Required
Format from any machine — helpful on locked-down corporate laptops.
Completely Free
Unlimited formatting with no signup or plugin install.
XML Formatting Tips
- •Declare encoding explicitly: Ensure the XML declaration matches actual UTF-8 content to avoid mojibake in feeds.
- •Preserve CDATA when needed: Wrap script or HTML snippets in CDATA sections so formatters do not escape them.
- •Namespace prefixes matter: SOAP and SVG rely on xmlns — do not strip prefixes when minifying for reuse.
- •Validate after external edits: Hand-edited RSS dates and SVG paths break easily — reformat to catch typos.
- •Minify only for transport: Keep a pretty version in source control; minify copies for wire logging.
- •Watch entity references: Escape & < > in text nodes — invalid entities fail strict parsers immediately.

Frequently Asked Questions
Can I both beautify and minify XML?
Yes. Choose pretty-print mode for readable indentation or minify mode to remove extra whitespace.
Does the formatter validate XML?
It checks well-formedness — matching tags, valid nesting, and parseable structure. It does not validate against XSD or DTD schemas.
Is my XML uploaded to a server?
No. Formatting runs entirely in your browser. Documents never leave your device.
Can I format SOAP envelopes?
Yes. SOAP XML with Header and Body elements formats like any other XML document.
Will RSS and Atom feeds work?
Yes. Syndication feeds are XML — pretty-printing makes channels and items easier to audit.
Can I format SVG files?
Yes. SVG is XML-based; the tool indents paths and attributes for easier manual edits.
Is this XML formatter free?
Yes. Free unlimited use with no registration or downloads.
Why does formatting fail?
Usually unclosed tags, illegal characters, or mismatched open/close element names. Fix the reported line and try again.
