You will get Python Data Cleaning & Automation: Convert Messy JSON/CSV to Clean Data


Project details
Your data is a mess. Nested JSON files, inconsistent formatting, and missing values. It's keeping you from getting the insights you need. I'll transform that chaos into clean, organized data you can actually use, and I'll build you a Python script so it happens automatically next time.
I am a Physicist and Data Analyst who applies scientific rigor to your business data to ensure zero errors in your reporting, while others might clean data manually.
What sets this project apart:
Scientific Logic: I don't just "move" data; I analyze its structure to ensure the cleaning logic is robust and error-free.
Automation-First: I use Python and Pandas to create scripts that you can reuse, saving you hours of manual work in the future.
Best Practices: Every project is handled with professional standards, including Git for version control and clean, documented code.
Complex Data Specialist: I specialize in "flattening" difficult nested data that standard tools often struggle to handle.
My goal is to turn your data chaos into structured, actionable insights you can trust.

Data Analyst with a Bachelor Degree in Physics
Caracas, Venezuela - 5:06 pm local time
🔹 I help businesses analyze, clean, and visualize data so they can make better decisions.
🔹 I specialize in Python, SQL, and BI dashboards (Power BI, Grafana) to transform raw data into clear, actionable stories.
🔹 I also have experience with machine learning workflows, including reinforcement learning and predictive modeling.
💡 What I can do for you:
Build dashboards that communicate results clearly.
Clean messy data and prepare it for analysis.
Write SQL queries and automate reports.
Support academic or technical research with data analysis.
I enjoy projects where I can learn something new and deliver results that make an impact. If you need flexible, reliable, and detail-oriented data work, I’d love to help.
Steps for completing your project
After purchasing the project, send requirements so Mariangel can start the project.
Delivery time starts when Mariangel receives requirements from you.
Mariangel works on your project following the steps below.
Revisions may occur after the delivery date.
Data Audit & Structural Analysis
I analyze your raw data to identify its structure, nesting levels, and inconsistencies. This initial "check-up" ensures the script I build will handle your data perfectly.
Custom Python Scripting & Automation
I develop a modular Python script (using Pandas) to extract and clean your data automatically. I follow coding best practices and use Git for version control to ensure reliability.
