This wouldn't happen to work with Pokebank Pokemon, would it?
As far as I know, you can use this to catalog pretty much any Pokemon you want. It isn't tied into the actual games in any way that it's only limited to x and y. However, all move names, typings and other things of that nature are based on gen 6, so some info may be inaccurate if you want to use the sheet to plan for other gens.
Was there any plan down the line for making this accessible for more than just Excel?
At the moment, no. In the long run I intend to look into turning this into an android app, but I don't have any plans to make this work for open office, google spreadsheet or other things like that. It would take more time than I am interested in spending I'm afraid.
So for now it's just Excel. Sorry about that! But really this is just a personal project that got big enough that I felt it was worth sharing, so I was never really planning to look into other spreadsheet programs.
Yes, but you now need to use the second link. It is listed as "without types" but it actually displays types. It uses the second link because there is only one version now, and it is simply called "Pokemon Team Builder". Unfortunately I could not edit the original post to explain this, although I did mention it a few posts back. Sorry about the confusion!
