XML Formatter – Free Online Tool
Free online XML formatter, validator, minifier, and tree viewer with XPath copy, attribute sorting, XML stats, upload, and download. 100% client-side.
Free XML Formatter Built for Real XML Files
ToolsMint XML Formatter formats and validates XML entirely inside your browser. Paste a sitemap, RSS feed, SVG file, SOAP response, Android manifest, plist, XHTML snippet, or application config and get clean, readable XML with configurable indentation, optional text trimming, and attribute sorting.
Validate, Minify, and Inspect XML in One Place
Most XML tools only beautify text. This tool also checks XML syntax, minifies XML for compact payloads, shows a collapsible XML tree, copies XPath-style paths for nodes, and calculates useful stats such as root element, element count, attribute count, comments, CDATA blocks, namespaces, depth, and file size.
Private XML Formatting for Sensitive Data
XML often contains production configuration, API payloads, identifiers, security metadata, internal URLs, or customer-related data. This formatter processes everything locally with browser APIs, so your XML is not uploaded, stored, logged, or sent to a server.
Best Uses for This XML Tool
Use it to debug malformed XML responses, clean generated sitemaps before submission, inspect RSS and Atom feeds, review SVG structure, read compact SOAP envelopes, format Android manifest files, check XML config files, and make copied XML from logs or AI outputs easier to understand.

Frequently Asked Questions
Everything you need to know about the XML Formatter.
Is this XML formatter free?
Yes. The XML Formatter is free, unlimited, and does not require an account. You can format, validate, minify, copy, and download XML directly in your browser.
Is my XML uploaded to ToolsMint?
No. XML formatting, validation, minification, tree generation, and stats all run locally in your browser. Your sitemap, config, SVG, feed, or API payload is not sent to a server.
Which XML files can I upload?
You can upload common XML-based files such as .xml, .svg, .rss, .atom, .xhtml, .plist, .config, and .txt files. The tool reads the file as text and processes it locally.
Can this tool minify XML?
Yes. Switch the output mode to Minify to remove unnecessary whitespace and produce a compact XML string. You can then copy it, download it, or use it as input again.
What does the XML tree view do?
The tree view shows document nodes, elements, attributes, comments, CDATA blocks, and text nodes in a collapsible outline. It also provides XPath-style paths you can copy for easier debugging and documentation.
Can I use this for XML sitemaps and RSS feeds?
Yes. It works well for XML sitemaps, RSS feeds, Atom feeds, and other structured XML documents where readable formatting, validation, and quick inspection matter.
