Find & Replace
Find every occurrence of a word or pattern in your text and replace it, with optional case-sensitivity and regex.
Paste in a block of text, type what you want to find and what to replace it with, and the tool updates the text instantly. Turn on case-sensitive matching when capitalisation matters, or switch on regex mode to use pattern matching for more advanced find-and-replace jobs, like removing all digits or matching flexible word patterns.
How to use it
- Paste your text into the main box.
- Type the text (or regex pattern) you want to find.
- Type the replacement text.
- Toggle case-sensitive or regex mode if needed, then click Replace All.
Frequently asked questions
What does regex mode do?
It treats your 'find' field as a JavaScript regular expression instead of plain text, letting you match patterns like \\d+ for numbers or word boundaries.
Is the replace case-sensitive by default?
No, by default matching ignores case. Turn on the case-sensitive toggle to match exact capitalisation.
Can I undo a replacement?
Yes — just re-paste your original text, since replacements only affect the text currently in the box, not any saved file.
