Frequently Asked Questions
What is regex mode?▾
Regex mode allows you to search using regular expressions, a powerful pattern matching syntax. For example, \d+ matches one or more digits, and [A-Z]+ matches one or more uppercase letters.
What does "whole word" matching do?▾
When enabled, the search term only matches when it appears as a complete word, not as part of a larger word. For example, searching for "cat" will not match "category".
How does Replace All work?▾
Replace All replaces every occurrence of the search term with the replacement text at once. You can also use Replace Next to step through matches one at a time.
Is my data secure?▾
Yes, all processing runs in your browser. No text is sent to any server.
Can I use capture groups in regex mode?▾
Yes. In regex mode, you can use capture groups in the search pattern and reference them in the replacement with $1, $2, etc. For example, search for (\w+)@(\w+) and replace with $2/$1.
Is the search case-sensitive by default?▾
No. By default, the search is case-insensitive. Toggle the case-sensitive option to match exact letter casing.
Does this work on mobile devices?▾
Yes. The find and replace tool runs entirely in your browser and works on any device with a modern browser, including phones and tablets.
