Frequently Asked Questions

Find answers to common questions about this tool.

Does the tool support regular expressions for search?

Yes. Toggle the "Regex" switch to use JavaScript regex patterns. You can use capture groups in the search pattern and reference them as $1, $2 in the replacement.

What happens if my replacement text contains special regex characters?

When regex mode is off, special characters are treated as plain text. When regex mode is on, characters like . + * need to be escaped with a backslash.

Can I see a preview of changes before applying them?

Yes. The tool shows a live preview with diffs. The changed text appears below the input with modifications highlighted.

Is there a limit on text size or number of replacements?

The input limit is 500,000 characters. There is no limit on the number of replacements, but very large texts may cause slow performance.

Does the tool replace across multiple lines?

Yes. In default mode, search spans across line breaks. Toggle "Single Line" mode if you only want to match within each line.
