Everyday utilities for developers, testers & analysts

List Comparator

Quickly compare two lists, find overlaps, uniques, and duplicates. Paste from Excel, CSV, or any text source.

i You can paste values directly from Excel or CSV. Commas and new lines are treated as separators.

Sort mode:

List 1 (0)

List 2 (0)

Comparison Results

Compare settings affect these results (only/common). Sorting options only affect the sort arrows near each list.

i Give your lists names above to have those labels reflected here in the result headings.

Only in List 1 (0)

    Common in List 1 & List 2 (0)

      Only in List 2 (0)

        Duplicates

        Duplicates use the same compare settings (case sensitivity). “Remove duplicates” only shows a deduplicated version you can copy; it does not alter the original lists.

        i Use “Show duplicates” to find repeated values, or “Remove duplicates” to get a clean copyable list.
