Data Cleaning (Excel / Python)

$8/hr Starting at $25

Is your data full of duplicates, missing values, wrong formats, and messy columns? I will clean it up and hand back a structured, analysis-ready dataset.


Bad data kills good decisions. Before any dashboard or model can work, the data underneath has to be clean. This is the step most people skip — and it is why their reports break.


What I fix:

- Remove duplicates and blank rows

- Standardize date formats, text casing, and number types

- Handle missing values (fill, flag, or remove)

- Merge and reshape multiple sheets or tables

- Rename columns and restructure layout for analysis

- Flag anomalies and outliers with notes


Tools: Python (Pandas), Microsoft Excel, Power Query


What you get: A cleaned file (Excel or CSV) plus a short summary of what was changed and why. Any suspicious patterns found in the data will be flagged and explained before the project closes.


Turnaround: Most small datasets completed within 24 hours. Share the file details or describe the dataset in a message — an honest scope estimate will follow before any commitment is needed.
