You will get a professional data cleaning and formatting service for Excel or CSV files
Project details
You will get clean, accurate, and well-structured Excel or CSV data using Python-powered automation.
I specialize in transforming messy spreadsheets into reliable datasets by removing duplicates, fixing invalid entries, and applying consistent formatting. Unlike manual Excel edits, my process is automated, fast, and scalable.
What makes this project different is the focus on accuracy and transparency. Every delivery includes a cleaned file and a clear summary report showing exactly what was changed.
This service is ideal if you need clean data for analysis, reporting, CRM imports, or daily business operations. I make sure your data is ready to use — without manual errors or guesswork.

Ankara, Turkey - 6:44 am local time
I work mainly with PHP, Python, and MySQL to develop backend systems, data processing tools, and automation scripts that help businesses reduce manual work and improve efficiency.
I have experience in:
* Backend development (PHP / Python)
* Database design and MySQL optimization
* API development and integration
* Data cleaning and processing (CSV, Excel, logs)
* Automation scripts and CLI tools
My focus is on writing clean, maintainable, and practical solutions that solve real business problems.
I am comfortable working on bug fixing, improving existing systems, or building small to medium-sized backend features from scratch.
If you need someone reliable to handle backend tasks or data-related automation work, I can help.
