Cómo usar: Find and Replace
- Paste your text on the left.
- Type what to find and what to replace it with. Add more rules for several replacements in one go — they run top to bottom.
- Use Match case, Whole words or Regular expression (with
$1,$<name>in the replacement) as needed. - Switch to Matches to see what was found, then copy the result.
Tips
- Whole words stops “cat” from also changing “category”.
- Leave Replace empty to delete every match.
- In the replacement,
\ninserts a new line and\ta tab — handy for splitting a comma list into lines.

Preguntas frecuentes
How do I replace multiple words at once?
Click “+ Add rule” for each word and its replacement. All rules run in order on the same text.
How do I use regex capture groups in the replacement?
Turn on Regular expression, put parentheses around parts of the pattern and use $1, $2 (or $ for named groups) in the replacement.
How do I replace with a new line?
Type \n in the replacement field — it becomes a line break. \t becomes a tab.
