What is the difference between case sensitive and case insensitive search?

Case sensitive search treats 'Hello' and 'hello' as different words, while case insensitive treats them as the same. Use case sensitive when you need exact capitalization matches.

How do regular expressions work in this tool?

Regular expressions allow complex pattern matching. For example, '\d+' matches numbers, '[A-Za-z]+' matches words. Enable the regex option and enter your pattern in the find field.

What does 'Whole word only' do?

Whole word matching ensures only complete words are replaced, not partial matches. For example, finding 'cat' won't replace 'caterpillar' when enabled.

Can I undo a replacement?

Yes, you can modify the replacement text and run the tool again, or use the original text to start over. The tool processes text instantly without permanent changes.

Is there a limit to text size?

The tool can handle large documents, but very large files (over 10MB) may affect browser performance. For extremely large files, consider processing in smaller chunks.

How do I replace multiple different terms at once?

For multiple replacements, run the tool multiple times with different find/replace pairs, or use regular expressions with alternation patterns like '(term1|term2|term3)'.
