Tips for Power Users

Chain Replacements

Use 'Apply to Input' to chain multiple find-and-replace operations on the same text.

Regex Capture Groups

Use parentheses in regex to capture groups, then reference them with $1, $2 in the replacement.

Escape Special Characters

In regex mode, special characters like . * + ? need to be escaped with \ to match literally.

Frequently Asked Questions

Enter your text, specify what to find and what to replace it with. The tool instantly shows the result with highlighted changes. You can replace all occurrences at once or see them highlighted first.
Yes! Enable 'Use Regex' to search using regular expression patterns. This allows powerful pattern matching like finding all emails, phone numbers, or custom patterns. Use capture groups with $1, $2, etc. in the replacement.
When enabled, 'Hello' will match 'hello', 'HELLO', and 'HeLLo'. This is useful when you want to find all variations regardless of capitalization. The replacement will use the exact case you specify.
For multiple replacements, you can chain operations or use regex with alternation (word1|word2|word3). For complex multi-replacements, consider using the tool multiple times or a regex pattern.
When enabled, searching for 'the' won't match 'there' or 'other'. It only matches complete words separated by word boundaries like spaces, punctuation, or start/end of text.
