I will clean, organize, and optimize your small or medium-sized business data in Excel spreadsheets and CSV files.


I can help clean and prepare a wide range of business data, including:

  • Customer data
  • Employee data
  • Financial data
  • Sales data
  • Operations data
  • Inventory data
  • Project data


Data cleaning services include:

  • Removing duplicate records
  • Fixing inconsistent or incorrect data
  • Standardizing names, dates, categories, and other fields
  • Splitting or combining columns
  • Filling missing values where appropriate
  • Restructuring spreadsheets for easier use and analysis
  • Cleaning and formatting CSV files
  • Creating lookup and reference tables
  • Preparing data for analysis, reporting, SQL, or Power BI


My goal is to turn messy or inconsistent spreadsheets into clean, organized, analysis-ready data that you can actually use.
