The Free Online XML Formatter is a powerful developer utility designed to clean up and validate XML data. XML (Extensible Markup Language) is notorious for becoming unreadable when minified or generated by machines.
Whether you are debugging a SOAP API response, analyzing a Sitemap, or editing a configuration file, readability is paramount. Our tool parses your XML string, applies proper indentation, and color-codes the syntax to make the structure clear.
Why use a Cloud-Free Formatter?
Many online formatters send your data to their backend for processing. For sensitive configuration files or proprietary data, this is a security risk. ToolsAid processes everything locally on your device (Client-Side), ensuring your data remains private and secure.
Frequently Asked Questions
Is my XML data safe?
Absolutely. This tool runs entirely in your browser using JavaScript. Your sensitive XML files (like sitemaps or SOAP requests) are **never** uploaded to our servers.
Can I format invalid XML?
We attempt to parse and format it, but if the syntax is broken (e.g., missing closing tags), the validator will highlight the specific line number error so you can fix it.
Does this support large files?
Yes, we use the optimized Ace Editor engine which can handle large XML payloads smoothly without freezing your browser.
