About This Tool

IDE-Grade XML Processing

Unlike simple regex-based cleaners, our XML Formatter uses a full structural parsing engine. This ensures that complex entities, namespaces, and large CDATA blocks are handled with mathematical precision, preventing data corruption during formatting.

Why Use This Tool

Why use our tool?

Privacy is our priority. Most online formatters upload your data to a server for processing. Our tool runs 100% client-side, meaning your sensitive XML data (like config files or API payloads) never leaves your computer.

FAQ

What is XML formatting?
XML formatting (or beautifying) is the process of adjusting the indentation and line breaks in an XML document to make it easier for humans to read and debug, without changing the underlying data structure.
Does this tool support CDATA and namespaces?
Yes. Our formatter is powered by a robust engine that correctly identifies and preserves CDATA sections and XML namespaces (xmlns), ensuring your data remains valid after formatting.
Can I remove comments from my XML?
Absolutely. Toggle the 'Strip Comments' setting in the sidebar to automatically remove all <!-- comments --> from the output, which is useful for reducing file size.
Is my XML data kept private?
Yes. Like all tools on DevToolkit, the XML Formatter runs 100% client-side. Your data never leaves your browser and is never sent to our servers.
