Is your structured data messy, inconsistent, or not ready for analysis?

I will professionally clean and organize your structured datasets (Excel, CSV, SQL exports, spreadsheets) and prepare them in the exact format you need.

What I can do:

·      Fix formatting inconsistencies

·      Standardize values into a unique/consistent format

·      Handle missing values (fill, flag, remove - based on your preference)

·      Detect and correct data entry mistakes

·      Basic text cleanup (grammar/spelling in structured text columns)

·      Remove duplicates

·      Rename/restructure columns

·      Convert data into your requested format

·      Prepare clean analysis-ready datasets

Bonus:

I can also provide a second cleaned version with outlier detection/removal for comparison.

Deliverables:

·      Cleaned dataset (main version)

·      Outlier-cleaned alternative version

·      Summary of performed cleaning steps
