I developed a Windows desktop application using Python to simplify repetitive spreadsheet cleaning tasks.

The tool allows users to import Excel and CSV files, identify duplicate records, select columns for comparison, remove duplicates, and export cleaned datasets without modifying the original files.

Import Excel (.xlsx) and CSV files.

Preview spreadsheet data.

Detect duplicate records based on selected columns.

Remove duplicate entries.

Export cleaned data to Excel or CSV.

Run as a standalone Windows executable.

Python, Tkinter, pandas, openpyxl, and PyInstaller.

In a sample dataset containing nine records, the application identified three duplicate entries, leaving six unique records.

I designed, developed, tested, and packaged the application as a Windows desktop tool.

Useful for small businesses, administrative teams, inventory management, and professionals who regularly work with spreadsheet data.

Project type: Personal portfolio demonstration.
