Find and Replace Text
Find and replace every match in your text, with optional regex and case control.
Every match is replaced at once. Turn on regular expression for pattern matching — then $1, $2 in the replacement insert captured groups. Turn off case sensitive to match regardless of capitalisation. Everything runs in your browser; nothing is uploaded.
How to find and replace
Paste your text, type what to find and what to replace it with, then read the result below. Use the empty replacement box to simply delete every match. The replacement count updates as you type.
Regex and case options
Turn on Use regular expression for pattern matching and backreferences in the replacement. Turn off Case sensitive to match regardless of capitalisation. Everything runs locally in your browser.
Questions
Does it replace every match at once?
Yes. Every occurrence of your search term is replaced in one pass and the result shows how many replacements were made, so there's no need to click through matches one at a time.
How do I use a regular expression?
Turn on Use regular expression to treat the Find box as a pattern. You can then match things like digits with \d+ or email-shaped text, and insert captured groups in the replacement with $1, $2, and so on.
What does case sensitive control?
When on, the search matches capitalisation exactly. When off, "Cat", "cat" and "CAT" are all treated as matches for the same term.
