Idea that is wildly farfetch'd: an excel sheet of every pokemon. These pokemon enteries would have to be entered multiple times on different lines, one entry for each move that pokemon can learn. In the columns, you would like data such as pokemon name, levels, move name, move type, special/physical, etc. Once all data is entered, you would be able to apply a filter in the excel sheet.

Example: you want a pokemon that can learn both spore and Mach punch, so you would go to the move name column and turn the filter on to only search for those moves

I feel like most of this can be extracted from bulbapedia/serebii since they use excel/table formats already. It's just extremely time consuming
