C++ developer with Reverse engineering and Pivot table experience

We are looking for someone very experienced in IDA Pro (or Ghidra), has good knowledge of C++ desktop (PC), and knowledge about Excel and pivot tables. I am looking to see how a pivot table has its data stored in memory. If useful, the Pivot table storage format is open: [login to view URL] or [login to view URL] The output of this project should be an example C/C++ program that shows a very, very basic example of how a 5-row csv of data would be stored in an Excel pivot table (stored, not necessarily queried). let me try and explain it a bit more. I'm not interested in building an app on top of the pivot table, but only seeing how it works (or is stored, internally, in memory) within the application itself. For example, when creating/refreshing a pivot table: [login to view URL] Do you have access to the PC Excel binary? How many hours do you think this would take you and how would you like to proceed? Do you want to first see if you think it's "do-able" (by opening the binary, etc.) and then you can let me know how many hours / how to proceed?
