How to use, limits & privacy

Choose a supported UTF-8 text file and a mode. Email extraction is an ASCII syntax heuristic, not address verification; URLs stop at whitespace or quote/angle delimiters and trailing sentence punctuation is removed. Delimited mode finds nonoverlapping pairs, skips unmatched endings and preserves nested delimiter text literally. Maximum 10,000 matches. Matches, including sensitive data, stay local; results are plain text, never active links. No redaction is performed.

Text: UTF-8 only, 4 MiB; CSV: 50,000 data records, 200 columns, 500,000 cells; exports: 16 MiB.

Inputs are never uploaded. Results are rendered as text or a locally generated image. Original files remain unchanged. Changing input invalidates previous results.
