About HTML Beautifier
HTML Beautifier is intended for a specific, repeatable task rather than a general-purpose editor. Beautify and indent your HTML code. The result changes when the source data or selected options change, so it is easy to run a second comparison.
What to prepare
The code, structured data, expression, token, or sample value requested by the interface.
What the result represents
A transformed, generated, or diagnostic result for the submitted technical input.
A practical example
A practical way to use it is to inspect a small representative sample before applying the same change in a production workflow. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.
