Built using Python with Streamlit, Pandas, and Openpyxl, this lightweight application simplifies the tedious task of combining spreadsheet data from multiple sources.
Simply upload a ZIP file containing your Excel sheets, and the app will extract and merge all .xlsx files into one unified dataset. You can then download the merged result as either CSV or Excel format with just one click.
