Thanks Ted and Dave for the reponses!  It turns out that in my current case
the DataToClip approach works perfectly.  I was totally surprised that it
could be so simple. (I was using copy to type XL5 when I wrote to a file so
I expected I would need to pass that detail to DataToClip.  I guess the
clipboard only cares about the values.)  Doing it this way eliminates the
need to create a file, upload the file to Google Drive, and find and import
that file to Sheets

If I get into a situation where I need a more elegant solution I can
consider ODBC or Chilkat.

Thanks again - Joe
