Practice Sales Dataset

Practice your Excel and data cleaning skills using this free messy e-sales dataset.

This dataset contains common real-world data issues including inconsistent text formatting, missing values, data type issues, duplicate records, invalid values, inconsistent dates, and formatting problems in identifiers such as Order IDs.

You can use this dataset to follow along with my videos, practice independently, or test your own cleaning workflows.

A data dictionary is included to help you understand the purpose of each column and identify issues more effectively.
