Question 1

How do I replace multiple words at once?

Accepted Answer

Type one find/replace pair per line in the rules box, using your chosen separator (default is comma). Paste the text to transform in the input box, and every rule is applied in order. The preview on the right shows the result with replacements highlighted.

Question 2

What separator should I use between find and replace?

Accepted Answer

The default is a comma (,), but you can switch to a tab, pipe (|), equals (=) or arrow (=>). Pick whichever does not collide with the text you are searching for.

Question 3

Can I use regular expressions?

Accepted Answer

Yes. Switch the mode to Regex and each find pattern is treated as a JavaScript regular expression. Use $1, $2 in the replacement for capture groups. Invalid regex patterns are skipped and reported.

Question 4

Is my text uploaded anywhere?

Accepted Answer

No. Every search and replace runs entirely in your browser. Your text never leaves your device.
