Is your contact list full of repeated records, inconsistent fields or columns that do not match your CRM?


I clean Excel contact lists and prepare CSV files against your supplied CRM import template.


What You Get:

  • Exact duplicate checks using agreed keys
  • Trimmed spaces and consistent field names
  • Email syntax checks and flagged issues
  • Phone-format cleanup using supplied country rules
  • Columns mapped to your import template
  • Missing required fields flagged for review
  • Cleaned CSV and a change summary


Basic covers 500 contacts, Standard 2,000 and Premium 5,000. Each package includes one source table, one target template, up to 15 fields and five agreed cleanup rules.


Why Choose Me?

I confirm the matching rules, preserve supplied identifiers and flag uncertain records. I work on a copy and explain changes before you import.


Email syntax checks do not verify mailbox existence or deliverability. Lead sourcing, enrichment, fuzzy matching, CRM uploads and automation are separate services. I do not guess missing data or change consent status.


Send a sample list and your CRM import template. Let's confirm the required fields and cleanup scope before ordering.
