I will clean and deduplicate your excel or CSV customer list

Need a cleaner customer or contact list?

I clean and organize existing Excel and CSV files using rules agreed with you.

Within your selected package, I can:

- Remove duplicate records using agreed columns and a clear rule for which record to keep (Standard and Premium only).

- Remove extra spaces and apply agreed text formatting.

- Standardize unambiguous dates to your chosen format.

- Organize columns for easier use.

You receive a cleaned copy and a short summary of the changes. Your original file remains unchanged.

Ambiguous dates, uncertain matches and conflicting records are flagged for your review. I do not guess names, fill in missing facts or merge uncertain matches automatically.

This service covers the data you provide. It does not include finding new contacts, web scraping or email validation.

Check the package limits before ordering. For complex files or work outside those limits, message me through Fiverr with an anonymized sample so I can confirm the scope.
