About this service

Summary

From removing duplicates and fixing formatting to standardizing entries and handling missing data, I ensure your dataset is analysis-ready. With a strong background in business data analysis and a detail-oriented approach, I provide transparent results along with a summary report of the cleaning process — something most freelancers skip.
