Free lead list cleaner that does everything in one pass — email validation, name formatting, phone normalization, deduplication, and missing field detection. Upload a CSV or paste data directly. The tool auto-detects name, email, phone, and company columns, then applies all fixes at once. Download a clean CSV ready for CRM import plus a detailed issues report. A free alternative to the data-cleaning features in Clay ($134/mo) and Apollo ($49/mo). All processing runs in your browser — your lead data never touches a server.
Seven operations in one pass: (1) email syntax validation — catches missing @, double dots, invalid TLDs, (2) email normalization — lowercase, trim spaces, (3) name formatting — "john smith" becomes "John Smith", (4) phone formatting — any format becomes (xxx) xxx-xxxx, (5) exact duplicate removal, (6) missing field flagging — highlights rows where email or name is blank, (7) whitespace cleanup — strips leading/trailing spaces from every cell.
Export your list as CSV. Drop it here. Check the operations you want (all are on by default). Click Clean Lead List. Review the issues tab for anything that needs manual attention. Download the clean CSV and import it. You'll have fewer bounced emails, consistent formatting, no duplicates, and clean CRM data from day one.
