About this Gig

I will clean and preprocess your dataset using Python (Pandas, NumPy) or Excel when needed. My goal is to turn messy, inconsistent, or unstructured data into a clean, usable format ready for analysis or modeling.


What I can do:

  • Remove duplicates, fix formatting, handle missing values
  • Detect and correct inconsistencies
  • Basic outlier and anomaly detection
  • Encode categories, split columns, merge datasets
  • Simple visualizations to confirm data quality


What you get in this basic package:

  • A clean and organized dataset
  • Standard preprocessing steps
  • A brief summary of issues found and actions taken
  • Optional simple charts to visualize improvements


This service is ideal for students, small business datasets, surveys, and anyone preparing their data for analysis or machine learning.
