Comment utiliser : 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.

Puis-je installer Find and Replace en tant qu’application web et l’utiliser hors ligne ?
Oui. Find and Replace est une application web installable (PWA) : elle s’installe depuis votre navigateur, sans passer par une boutique d’applications. Cliquez sur « Installer l’application » en haut de cette page dans Chrome ou Edge (Windows, macOS, Linux, ChromeOS) ; sur Android, utilisez « Partager » → « Ajouter à l’écran d’accueil » sur iPhone et iPad ; ou « Fichier » → « Ajouter au Dock » dans Safari 17+ sur Mac. L’application s’ouvre alors dans sa propre fenêtre avec sa propre icône, et comme elle s’exécute entièrement dans votre navigateur, elle continue de fonctionner hors ligne. Firefox sur ordinateur de bureau ne permet pas d’installer d’applications web. Comment fonctionne l’installation.
