Pretty-print messy XML with clean indentation, or minify it, and find unclosed tags.
Tool inputs stay in your browser · optional AI search sends your query
Good to know: Every opening tag like <item> needs a matching </item>. The tool tells you which tag is not closed.
How to use it (step by step)

- 4Press Copy and paste the result wherever you need it.
Words to know
- YAML / XML
- Other text formats for storing settings and data. Same idea as JSON, different writing style.
- Minify
- Removing spaces, line breaks and comments so code is smaller and loads faster. The computer reads it the same way.
- Beautify / format
- Adding line breaks and indentation so code is easy for humans to read. It does not change what the code does.
- Indentation / line endings
- Indentation is the space at the start of a line that shows structure. Line endings are invisible characters that end each line: LF (Mac/Linux) or CRLF (Windows).
