About this tool
Clean line-edge whitespace, blank lines and repeated whitespace, or add the same prefix or suffix to every line. Replacement searches for a literal string rather than a regular expression. Row order is preserved; this tool does not sort or deduplicate lines. Content is processed locally in your browser.
How to use
- Paste the multiline text to clean.
- Choose trimming, blank-line removal, whitespace collapsing, prefix/suffix or replacement and enter the relevant parameters.
- Run, inspect row order and replacement scope, then copy or download.
Frequently asked questions
Does replacement support regular expressions?
No. The search string is matched literally; an empty search string is rejected.
Does removing blank lines reorder text?
No. It removes only lines that are empty after trimming; other lines keep their order.
