Before you download a random script from GitHub, you need to understand what you are fighting. Excel has two distinct types of password protection:
This locks specific cells or hides formulas/VBA code. It uses a very weak hashing algorithm (often just a 16-bit checksum).
Critical Takeaway: If you forget the open password for a heavily encrypted modern Excel file (.xlsx or .xlsm), no "remover" on GitHub can magically delete it. They must "recover" it, which takes time. Excel Password Remover Github

For this tutorial, we will use a hypothetical Python script based on the Excel-Password-Remover structure. Before you download a random script from GitHub,
