About this tool

This toolkit covers the comparison jobs that usually begin in a spreadsheet: checking imports, auditing IDs, reconciling exports, and reviewing changed text.

Start with the main two-list comparator, then use multi-list comparison or text diff when the structure of the problem changes.

  1. Choose the comparison tool that matches your input.
  2. Paste the source lists or text blocks.
  3. Copy the focused overlap, difference, or change result.
