About this Gig
Need reliable data for reporting or analysis? I will clean and transform your Excel or CSV files using Python and Pandas.
I can remove duplicates, standardize column names and formats, validate data types, handle missing values according to your instructions, and merge files when included in your package.
You will receive a clean, analysis-ready CSV/XLSX file and a concise summary of the changes. A reusable Python script and expanded data-quality checks are included in the Premium package or available as extras.
I never invent missing values or make unapproved assumptions.
Please share the file size, row count, desired output, and cleaning rules. For multiple sources, complex logic, or larger datasets, message me before ordering so I can confirm scope and delivery.
