Find and Replace

Regular expressions (regex) are a pattern language for searching text. For example, `\d+` finds any number, and `https?://\S+` finds a URL. Turn on Regex mode to use them in search.

By default, all occurrences are replaced. To replace only the first one, use regular mode—the tool replaces all occurrences automatically, but you can copy the part you need.

There is an “Ignore case” toggle. By default, case doesn’t matter: “Hello” and “hello” are treated as the same. Turn it on for an exact search.

In regular mode, all characters are searched as entered. In regex mode, special characters (., *, +, ?) must be escaped with a backslash: `\.` for a period.

The tool runs in your browser and processes text of any size with no limits. Very large texts (>1 MB) may make the display a little slower.
