You will get your messy data cleaned and transformed with Python
Project details
Is your data full of duplicates, missing values, inconsistent formats, or errors? I'll clean and transform it into a structured, ready-to-use dataset using Python (pandas). You'll receive a clean final file plus the Python script used — so the process is fully transparent and reusable.
What I handle:
-Duplicate removal
-Null and missing value treatment
-Format standardization (dates, numbers, text casing)
-Invalid value detection and correction
-Summary report of all changes made
Works with CSV, Excel, JSON, and TXT files. If you're not sure your data qualifies, message me first — I'll let you know within a few hours.

About Jean
Data Analyst & Excel Automation Specialist | Python, SQL & Reporting
North Bergen, United States - 8:39 am local time
With 5+ years of Excel experience and a professional background as a Data Analyst in the insurance industry, I've worked with high-volume datasets where accuracy and efficiency were critical. I used Excel VBA to automate workflows and reduce manual processing — real work, real deadlines.
Today I combine that experience with Python (pandas, matplotlib) and SQL to deliver:
- Data cleaning and transformation (ETL)
- Automated Excel/CSV reports with Python
- SQL queries for data extraction and summarization
- Clear visualizations and business summaries
I'm reliable, detail-oriented, and communicate clearly in English. If you have messy data or a manual process that needs automating, let's talk.
