Remove paste artifacts
Clean extra spaces and blank lines from text copied out of documents, spreadsheets, or logs.
Text Cleaner
브라우저 내부 처리
Trim whitespace, remove duplicates, sort lines, and slugify in one pass.
Text cleaning workflow
Text copied from the web or a PDF carries invisible whitespace and zero-width characters. Passed straight into code or data, they break string comparison and search. Deduplication, whitespace cleanup, sorting and slugify in one place get pasted text into a usable state.
Organize lists
Use duplicate removal and sorting to review keyword, URL, email, or config-value lists more easily.
Draft slugs
Turn titles into URL-friendly slug drafts for document paths and filenames.
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.
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.
Invisible characters survive copying
Text copied from the web or a PDF carries non-breaking spaces (U+00A0), zero-width spaces (U+200B) and directional marks. They look like spaces but break string comparison and search. That is why whitespace cleanup comes first.
Slugify results depend on the language
Turning non-Latin text into a slug gives different output per tool: transliteration, removal, or percent-encoding. Pick one convention for URLs and keep the team consistent, or links will diverge later.
Deduplication changes order
Removing duplicate lines keeps only the first occurrence, discarding some ordering information. For data where order matters, such as logs, keep the original before deduplicating. Sorting then deduplicating loses the order entirely.

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.
