Find and replace text with support for regex and case-sensitive matching
100% Private - Files Processed Locally
Your files never leave your device
Enter the text to process, set what to find and what to replace it with, and choose between plain matching, whole-word matching, case-sensitive matching, or regular expressions.
Simply enter your text, specify what to find and what to replace it with, and configure your matching options. Support for case-sensitive matching, whole word matching, and regular expressions gives you full control. All processing happens locally in your browser. No registration required.
Regex (Regular Expression) is a pattern-matching language that lets you find complex text patterns. Use it when you need to match patterns like email addresses, phone numbers, or variable naming conventions rather than exact text.
Whole Word matching ensures that only complete word matches are replaced. For example, searching for 'cat' with Whole Word enabled won't match 'catalog' or 'educate' â only the standalone word 'cat'.
Absolutely! All processing happens locally in your browser. Your text is never sent to our servers or any third party. We don't store or track any of your content.
Since the original text is preserved in the input field, you can always go back and try different replacement settings. The output is shown separately, so your original text is never modified.
