You will get Clean and Wrangle Your Data Using Python Pandas
Project details
Messy spreadsheets or fragmented CSVs? I clean, merge, and reshape them into analysis-ready data with Python/pandas.
What you get:
• Deduplication, type fixes, missing value handling
• Multi-file merges, column standardization, reshaping (pivot/melt)
• Custom validation rules (Advanced)
• Clean CSV/Excel + change log (all tiers)
• Reusable Python script (Standard+)
• Data quality report with before/after stats (Advanced)
Why me:
I built AutoCSV Profiler (7,334 LOC, 20 tests) and InsightfulPy (30 functions, 9 releases), two PyPI libraries with 9,200+ combined downloads. AutoCSV handles chunked processing for files larger than RAM. InsightfulPy adds batch visualization and data quality checks.
Across 12 Python projects (111K+ LOC), I've written 156 automated tests and manage multi-environment data pipelines (AutoCSV Suite: 6,535 LOC, 28 tests).
Expert Python, Pandas, NumPy, CSV, openpyxl, Excel Automation. IABAC Data Scientist (Grade A), NASSCOM (Gold), Kaggle Data Cleaning certified.
Every delivery includes a change log so you can see exactly what was transformed.
