The mapping exercise
Honestly, I am not sure I understand how this will be done without an Excel file on the mapping categories and their correspondence in Excel. Do we have an Excel version of the mapping correspondence? I mean, pages 3 through 8 of the "Mapping Explained" pdf file in Excel format?
All of this work is typically done in Excel manually (at least until ChatGPT came around - I've tried using it for this task in the Data Analysis with ChatGPT in Excel course). The PDF aims to provide some context and advice how to map different items.
