Can matching ignore capitalization?
Yes. Turn off case-sensitive matching to replace uppercase and lowercase variants.
Find and Replace Text
Replace matching text with optional case-sensitive matching.
Calculations happen locally. We do not send your values to our server.
Example
Finding “brown” and replacing it with “red” changes every matching occurrence in the entered text.
Calculation method
The find phrase is treated as literal text rather than a regular expression, then every case-sensitive or case-insensitive match is replaced.
Important notes
An empty search phrase is rejected. Review the output before replacing important source material because all matches change at once.
Frequently asked questions
Can I use regular expressions?
No. Search characters are escaped and treated as an exact literal phrase for predictable behavior.
Is the original text saved anywhere?
No. Finding and replacing happens only inside the current browser page.
