What formatting does well
Formatting reveals structure. It helps you see nesting, line breaks, wrappers, and repeated patterns that were impossible to inspect in one compressed line.
What formatting does not solve
- Invalid or surprising browser parsing behavior
- Broken nesting that still renders but causes maintenance issues
- Encoded content or template fragments pasted into the wrong context
Practical workflow
Format the markup with the HTML formatter, then use the diff checker if you need to compare the cleaned version against the original.
