I will deduplicate and validate your customer spreadsheet

I deduplicate and validate customer spreadsheets before you upload them to a CRM, email tool, support platform, or customer success system.

I can help identify likely duplicate contacts or companies, standardize names and formats, flag missing required fields, check obvious email or phone issues, and return a cleaner spreadsheet with a short issue summary.

Please do not send sensitive customer data. If your file includes real customer information, anonymize it first or send a sample plus your target import template.
