Frequently Asked Questions
Common questions about find and replace operations.
Can I run multiple find & replace rules at once?
Yes — that's the main advantage of this tool. Add as many rules as you need using the Add another rule button. Rules run in order from top to bottom, so the output of one rule becomes the input of the next. This lets you chain complex transformations.
How does Regex mode work?
When .* (Regex) is checked for a rule, the Find field is treated as a JavaScript regular expression. You can use capture groups in the Replace field with
$1, $2, etc. For example, Find \b(\w+)\s+\1\b and Replace with $1 removes duplicate consecutive words.What does "Whole word" matching do?
Whole word mode wraps your search term with word boundary anchors so it only matches complete words. For example, searching for "cat" with whole-word on will match "cat" but not "catch" or "scatter". This is useful when renaming variables or replacing short words that might appear inside longer words.
Is my text sent to a server?
No. All find-and-replace operations run entirely in your browser using JavaScript. Your text never leaves your device. Nothing is stored, logged, or transmitted to our servers.
What is the Diff Preview view?
Diff Preview shows a side-by-side word-level comparison of your original and replaced text. Added words are highlighted in green, removed words in red. It lets you verify every change before copying or downloading the output.
