When to use it
Use it when debugging copied HTML, email snippets, or generated markup.
What the result means
The output is a readable approximation of the tag tree.
Use notes
- It is meant for snippets, not broken full documents.
- Whitespace-sensitive inline content may need manual review.
- Script and style contents are not deeply formatted.
