About MatchMyLists
MatchMyLists is a privacy-first, browser-based list comparison and reconciliation tool for comparing, matching, cleaning, deduplicating, and reconciling lists and spreadsheet columns directly in the browser.
What it helps you do
Compare pasted lists and columns from CSV or Excel files to find exact matches, normalized variants, likely fuzzy matches, missing records and duplicates. Supported result categories can be exported as CSV or Excel files.
Private by design
Pasted lists and imported files are processed locally in the browser and are not uploaded to a MatchMyLists processing backend. Parsing, normalization, matching and export happen in your browser, with a dedicated worker for heavier work.
