(NOTE: I know, the code can be shorter by looping. This is just to make it functional before optimizing)
 
It generates the following xl/table content:
 
 
You will notice it does not have any xr3:uid etc
 
When I try reading the file using "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + gFName + ";Extended Properties=Excel 12.0" I get the following error: External table is not in the expected format.
 
I open the file in excel and save it back and the xl/table looks like this:
 
 
with all the unique IDs.
 
Using this file works.
 
How can I get this to happen on the initial output so the manual process of opening and re-saving doesn't have to happen?
