You will get a clean, structured Excel file ready for analysis with full documentation
Project details
Your data is messy. I make it clean, structured, and decision-ready.
I specialize in Excel data cleanup using Power Query ETL — removing
duplicates, handling missing values, standardizing inconsistent
formatting, and recalculating derived columns.
Every transformation is recorded in Power Query and remains fully
editable. Next month when you get new data — refresh in one click.
What you get: clean .xlsx file, README tab explaining every step
applied, and an anomaly report if issues are found in your data.
Recent project: cleaned 2,500-row fashion sales dataset — standardized
3 city name variants, flagged 1,210 missing prices, recalculated Sales
Amount across all records.
