Workflow
How to use it
- Paste the text you want to clean.
- Choose trimming, blank-line removal, duplicate removal, sorting, or slugify actions.
- Compare the result with the original so meaningful spacing or ordering is not lost.
- Keep the original before bulk edits, then copy the cleaned result.

Errors you will hit
Invisible whitespace survives
Text copied from the web often carries non-breaking spaces (U+00A0) or zero-width characters. They look identical but compare and sort differently.
Non-ASCII titles vanish in a slug
Slugs usually keep ASCII only, so a Korean or Japanese title can be stripped entirely. If you plan to use non-ASCII URLs, keep the encoded original instead.
Review
Things to check
Keep the original
Duplicate removal and sorting can change order. Preserve the source when sequence matters.
Review slugs
Automatic slugs are drafts. Before publishing URLs, adjust brand names, acronyms, and search intent manually.
