About Compare Two Lists

Compare two lists line by line to instantly see what is unique to each and what they share. Paste List A and List B, and the tool computes the set differences — items only in A, items only in B, and items in both — with optional whitespace trimming and case-insensitive matching. It runs entirely in your browser, so your data stays private.

How to use

  1. 1

    Paste your first list into List A and the second into List B.

  2. 2

    Choose whether to trim whitespace and ignore case.

  3. 3

    Read the three columns and copy any result you need.

Tip: All processing is performed locally in your browser with zero loss in quality and no upload limits.

Frequently Asked Questions

Each list is de-duplicated first, so every item is compared once regardless of how many times it appears in a list.

All processing happens locally in your browser. Your files are never uploaded anywhere.
