Text Find Replace

Replaces occurrences of a find string within your input text, with options for regular expressions and case sensitivity. In literal mode all matches are replaced; in regex mode the find pattern is compiled and applied globally.

1. Enter the text to find in the Find field. 2. Enter the replacement text in the Replace With field. 3. Toggle Use Regex if your find string is a regular expression. 4. Toggle Case Sensitive as needed. 5. Type your input text and click Replace. 6. Use Copy in the output header to copy the result.

With Use Regex on, the find string is compiled into a RegExp with the 'g' flag (plus 'i' when case-insensitive); invalid regex falls back to a literal split/join replacement. With Use Regex off, special regex characters in the find string are escaped automatically. The Replace button is disabled until the Find field has content.
