About this gig

I create small Python scripts to process Excel and CSV files.


This gig is best if you need to clean, filter, merge, split, convert or transform spreadsheet data without doing the same manual work again and again.


I can help with:

Excel to CSV or CSV to Excel conversion

Cleaning messy data

Filtering rows by rules

Merging multiple files

Splitting one file into several outputs

Renaming or restructuring columns

Creating a processed output file

Basic calculations or summaries


Basic package includes one small Python script for one simple Excel/CSV processing task. I will test the script and provide short instructions so you can run it.


Please contact me before ordering if your task includes many files, complex business rules, APIs, websites, databases or unclear requirements. This helps me confirm the scope before starting.

I build practical Python tools for automation, reporting, data processing and small web utilities. My focus is on clean, maintainable code and simple workflows that save time: Excel/CSV processing, PDF reports, internal business tools, dashboards, web scraping helpers, SEO/GEO audit tools and AI-assisted utilities. I have hands-on experience with Python, Flask, data processing, automation scripts, web tools and report generation. I prefer clear requirements, reliable outputs and solutions that are easy to use.
