Find and replace text
Replace every occurrence of a word, or use a regular expression for trickier cases.
Find and replace is a free tool that runs entirely in your browser, with no data ever sent to a server. Replace a word or a regular expression in a text.
Plain search or regular expression
Without the "regular expression" option, the search text is treated literally : every
character counts for itself. With the option on, standard JavaScript regular expression syntax
applies : \d+ for a run of digits, ^ and $ for the
start and end of a line, and so on.
What this tool does not do
This tool only applies the transformation described above, with no spelling correction and no understanding of the text's meaning. A text of tens of thousands of lines is processed instantly ; beyond that, the only limit is your device's memory.
Frequently asked questions
Can I reuse the matched text in the replacement?
Yes, in regular expression mode : use groups (...) in the search and $1, $2 in the replacement.
Is my data sent to a server?
No : the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.
Do I need to create an account or install anything?
No : the tool works directly on this page, with no sign-up and no install.
