Paste text, enter a literal search value, and extract the matching lines locally.
A QUICK WALKTHROUGH
How to use this tool
- Paste or type text.
- Enter the literal text to find and choose case sensitivity.
- Click Extract matching lines, then review or copy the result.
Literal matching
The search value is matched as plain text. Regular-expression syntax has no special meaning, and matching can be case-sensitive or case-insensitive.
Lines and empty queries
Line text is preserved exactly, including spaces and blank lines. An empty search value returns the original text unchanged. LF, CRLF, and CR line endings are accepted; output uses the first newline style found.
Local processing
Text processing and copying happen in this browser tab. No text is uploaded.
GOOD TO KNOW

Is the search a regular expression?
No. The search value is always treated as literal text.
What happens when the search value is empty?

Are spaces and blank lines preserved?
Yes. Matching lines are returned without trimming, and blank lines are kept only when they match an empty query.

Yes. LF, CRLF, and CR are accepted; output uses the first newline style found.
