5. Frequently Asked Questions (FAQ)
5.1 How does 'Match Whole Word' protect against accidental changes?
Whole Word matching ensures replacement only targets standalone words bounded by whitespace or punctuation. For example, replacing 'cat' will modify 'the cat slept' but leave 'catalog' and 'scatter' untouched.
5.2 Can I replace multiple different words at the same time?
Yes. Click '+ Add Pair' to define as many concurrent find-and-replace rules as needed. All pairs are processed sequentially in a single batch operation.
5.3 Does this tool support case-sensitive search?
Yes. Enabling 'Match Case' ensures that 'Apple', 'apple', and 'APPLE' are treated as distinct strings, preserving targeted casing during replacement.
5.4 Is my text data stored or sent to a server?
No. All find and replace operations run locally within your browser using client-side JavaScript. No text is ever uploaded, cached, or transferred over the network.
