Command Button to open 2 .CSV's in multiple tabs in excel workbook

[Astello]

I want to use command buttons to open two separate .csv files in the same excel workbook on different tabs. Is this possible?

Yes, I turned them into .xls files and then put them in the workbook. They're originally .csv output from another program, but it's fine for them to end up .xls
Thanks!

Yes, but I need to put them into Excel so I can run a macro on them. The things I need to do are difficult/impossible in Access, but quite simple in Excel.
