  2. Enter the word or phrase you want to change in the Find field.

  4. Toggle Case sensitive, Whole word only, or Use regular expression as needed.
  5. Read the result and the replacement count, then click Copy output.

Matching options explained

Matching ignores case by default; turn on Case sensitive to match exact capitalisation. Whole word only skips matches that sit inside a larger word. Use regular expression treats the Find box as a pattern, so you can match numbers, whitespace, or anything else — for full pattern building, try the regex tester.

Frequently asked questions

How does find and replace work?

Paste your text into the main box, type what you want to find, and type what to replace it with. Every match is swapped instantly as you type and the number of replacements is shown below the output. Leave the replace field empty to simply delete the matched text.

What do the case-sensitive and whole-word options do?

By default matching ignores case, so "cat" also matches "Cat" and "CAT". Turn on Case sensitive to match the exact capitalisation only. Turn on Whole word only to skip matches that are part of a larger word — with it on, "cat" will not match inside "category" or "cats".

How do I use regular expressions?

Tick Use regular expression and the Find box is treated as a JavaScript regex pattern instead of literal text. This lets you match patterns such as \d+ for numbers or \s+ for runs of whitespace, and use capture groups like $1 in the replacement. If the pattern is invalid, a red message explains the problem and your text is left untouched.

Is my text sent to a server?

No. This find and replace tool runs entirely in your browser with JavaScript. Your text is never uploaded, stored, or shared, so it is safe to use with private or confidential documents.

Can I replace across many lines at once?

Yes. The tool works on the whole document at once, no matter how many lines it contains, and replaces every occurrence in a single pass. There is no fixed size limit, though very large texts may be slower on older devices.
