How to use the XML Formatter

To get started with XML Formatter, enter or paste your source data in the input area. All processing happens client-side using modern browser APIs, so your data never reaches a server. Results appear instantly.

Why use the XML Formatter

Instead of opening a code editor or installing a CLI tool, use XML Formatter right in your browser. It handles the task locally, giving you fast, private results without context switching.

When to use XML Formatter

Reach for XML Formatter during code review when you want to verify that a snippet is well-formed, or when you are working on a remote machine and do not have your usual dev environment set up. It also helps when you want to share a clean, readable version of some data with a colleague who does not have the same toolchain installed.

Key features of XML Formatter

XML Formatter offers real-time validation so you catch syntax errors as you paste, multiple output modes (pretty-print, minified, highlighted) to suit different stages of your workflow, and zero configuration — open the page and start working. There are no login prompts, rate limits, or hidden charges.

Common use cases for XML Formatter

XML Formatter is frequently used for: converting log output from a compressed or encoded format into something human-readable during incident post-mortems; preparing cleanly formatted code samples for technical documentation or Stack Overflow answers; and quickly checking whether a third-party library returned data in the expected shape before writing assertions in unit tests.
