Format HTML

Make messy HTML easier to read, edit, and debug.

Use this formatter when you need to make messy HTML easier to read, edit, and debug. It is useful for quick browser-based checks before you commit a snippet, send an API request, or write a one-off script.

For code and data tasks, start with a small representative sample before running a larger payload. Watch for encoding, escaping, indentation, delimiters, and hidden whitespace because those details often explain confusing output.

When the output feeds another development task, JSON validator, JSON formatter, and regex test can help validate, format, inspect, or transform the result before it goes into code or an API.
