Structured data

Beautify and validate XML documents

SOAP responses, sitemap files, and Android manifests all become easier to reason about when they are formatted with consistent indentation. This formatter keeps namespaces intact, highlights mismatched tags, and lets you minify exports for production.

Human-friendly hierarchy

Paste XML snippets or load files directly. The formatter re-indents nested nodes, aligns attributes, and collapses long text blocks so you can immediately see parent-child relationships. Comments and CDATA sections are preserved exactly as written.

Toggle view modes to collapse nodes while auditing large documents. Quick find shortcuts help you jump to specific tags, saving valuable time during incident reviews.

Namespace aware
Prefixes remain attached to their declarations, helping you track which schemas power each element.
Validation hints
Unclosed tags or malformed attributes trigger inline warnings before you ship broken payloads.

Minify for transport

Need to embed XML inside environment variables or HTTP payloads? Flip to minify mode to strip excess whitespace without mutating content. This is ideal for templated configs or signature generation workflows.

All processing stays device-side, so you can inspect sensitive integration responses or proprietary config files without uploading them anywhere.

Download & share
Export formatted XML for teammates or copy the minified version into automation scripts with one click.
Diff-ready output
Combine the formatter with Diff Checker to compare production vs. staging manifests when debugging.

Perfect for

SEO teams

Validate sitemap.xml files before submitting them to search engines.

Mobile releases

Check AndroidManifest.xml or Info.plist exports for missing permissions.

Enterprise integrations

Work with SOAP or XML-RPC responses when onboarding legacy partners.

Build pipelines

Clean up Maven POM files or Jenkins configs so reviews focus on parameter changes.

Next step

Transform XML into other formats

After formatting, hop into the JSON to CSV converter or other FreeTools.run utilities to repurpose the data for analytics.

Frequently asked questions

What is XML?

XML (Extensible Markup Language) is a markup language similar to HTML, but designed to store and transport data. It is self-descriptive and platform-independent, making it a standard for data exchange.

Why format XML?

Raw XML is often generated as a single continuous string to save space, which is impossible to read. Formatting (or 'pretty-printing') adds indentation and newlines so you can visualize the document structure.

Can I convert XML to JSON?

While this specific tool focuses on formatting XML, we are working on a dedicated XML-to-JSON converter. For now, you can use this tool to clean up your XML before manually converting it.

Is this tool secure?

Yes. Your XML data is processed entirely in your browser. We do not store, record, or transmit your data to any server.

How to use XML Formatter

Follow these four quick steps to prepare and validate structured payloads right inside your browser—no downloads, no accounts, and no data leaving the FreeTools.run sandbox.

Step 1: Load your source data
Paste text, drag a file, or start with our curated sample to understand how the formatter workflow behaves with real inputs.
Step 2: Adjust tool options
Toggle presets, update formatting rules, or choose export preferences. All controls update in real time so you can preview the effect before committing.
Step 3: Review the live preview
Use the split-pane preview, inline validation, or diff output to confirm the transformation looks correct before you copy anything back into your project.
Step 4: Export or chain another tool
Copy the result, download a file, or jump into a related FreeTools.run utility (like Diff Checker or the QR Code Generator) to continue the workflow without leaving the browser.
