Frequently asked questions

How are words matched?

Matching is case-insensitive and ignores punctuation, so 'Cat,' and 'cat' count as the same word.

What counts as a duplicate?

Any word appearing two or more times. The list is sorted from most to least frequent.

Does it find duplicate lines too?

This tool focuses on words. Use the Remove Duplicate Lines tool for whole-line duplicates.
