What does this tool do?
Find & Replace lets you instantly locate words or patterns in a block of text and swap them for something else. Because it supports both plain-text search and regular expressions, it works for quick one-off fixes as well as complex pattern substitutions across long passages.
How to use it
- Paste your text into the input area.
- Adjust the options to fit your needs.
- Copy the processed text.
Regex, case and scope controls
Three checkboxes give you precise control over behaviour. With Regex off, your search term is treated as literal text, so characters like dots and asterisks carry no special meaning and won't cause accidental matches. Turn it on and you unlock the full power of regular expressions, including \d, capture groups and back-references such as $1. Case insensitive ignores letter casing, while Replace all decides whether you change only the first match or every occurrence.
Live preview and match counter
The result updates with every keystroke, and a counter shows exactly how many matches were replaced. If you write an invalid regular expression, the tool shows a clear error message instead of breaking, so you can debug your pattern with confidence. The output appears in a separate panel and the original text stays intact, letting you compare before committing and copy the result with a single click.
Frequently asked questions
What is the difference between plain text and regex search?
With Regex off, your term is matched literally and special characters are escaped. With it on, you can use full regular-expression syntax, including grouping and back-references.
Can I use captured groups in the replacement?
Yes. In regex mode, groups you capture with parentheses can be reused in the replacement field with expressions like $1 and $2.
Can I replace only the first match?
Yes. Uncheck Replace all and the tool changes only the first match in the text, leaving every other occurrence untouched.
