A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
This issue appears to be solved with the latest version (v16.0.1) of Filemaker's ODBC drivers, reported to be backward compatible to Filemaker Pro V12. Drivers can be downloaded from here:

I have FMP13 advanced and using the version 16.0.1 ODBC drivers can now successfully use Filemaker as a source and Excel 2016 Mac (v15.34) as a client.
Good luck!
