Find and Replace
Paste text, type what to find and what to replace it with, and swap every match at once. Find and replace is the fastest way to fix a repeated typo, rename a term across a whole document, strip out unwanted characters, or reformat data in bulk. This tool replaces all occurrences by default, and you can toggle case-insensitive matching so Cat and cat both get caught. For advanced edits, switch on regex mode to match patterns rather than plain text, which is powerful for things like collapsing spaces or removing digits. It reports how many replacements were made. Everything runs locally in your browser, so even sensitive documents never leave your device.
How to use Find and Replace
- Paste your text into the box.
- Enter the word or pattern to find.
- Enter the replacement text.
- Enable regex or case-insensitive if needed and run the replace.
