Using Mac Numbers to produce Excel file for placing in ID
I am on a Mac and do not have Excel. So I Export to -> Excel from Numbers. I then want to import this Excel file into ID.
ID will not place the file. I get the error message:

It just won't place it. However, I can use this same file in other programs (FileMaker) without issue.
Can anyone out there use Numbers to produce an Excel file and then place it in ID?? Is this a bug or am I missing something?
Thank you.
