The tool automatically groups results into categories like “all three,” “first two only,” and more — perfect for analyzing partner data or multichannel audiences. Use 3-way comparison to skip spreadsheets and get clean data in seconds.

This service lets you compare 3 lists online and instantly identify shared, unique, and overlapping values between them. Everything runs directly in your browser — no Excel, no scripts, no registration.
Just paste Lists A, B, and C into the input fields, click the button — and you’ll get:
- The full intersection across all three lists
- Items that appear only in A, only in B, or only in C
- Pairwise overlaps: A ∩ B, B ∩ C, A ∩ C
- Extended fuzzy mapping (if fuzzy matching is enabled)
Perfect for:
- Analyzing overlaps in large datasets
- Comparing multiple email lists
- Matching product catalogs, tags, or SKUs
- Preparing merged CSV files
You can export results as CSV or JSON. The tool is free, fast, and easy to use — especially helpful if you’re working with large datasets and need to remove duplicates and errors.
Comparing three lists online is a simple way to analyze multiple datasets at once — no complicated steps, just clean insights.
