Do you have a messy Excel, CSV, or CRM file that is full of duplicates, wrong emails, inconsistent phone numbers, or missing values?

I will professionally clean and organize your data so you can trust your reports and make better decisions.

I can help you with:

  • Cleaning and formatting Excel or CSV files
  • Removing exact and fuzzy duplicates
  • Fixing and validating email and phone number formats
  • Standardizing dates, names, addresses, and company names
  • Handling missing values (flagging, filling, or removing)
  • Splitting and merging columns (first/last name, city/state, etc.)
  • Preparing marketing-ready contact lists from CRM exports (HubSpot, Salesforce, etc.)

Tools I use:

  • Excel / Google Sheets
  • Python (Pandas) for larger or complex datasets

What you will receive:

  • A cleaned file (Excel/CSV) ready to use
  • A short report explaining what was fixed (e.g. how many duplicates removed, how many invalid emails, etc.)
  • 100% manual review of critical fields
