I trimmed down my data in excel from 48,000 to 10,000..just to get something to work.
Syntax of course was the issue. my field names did not match. After getting all that squared away.
Finally created a "Collection" from the excel workbook, along with my 3 fields and was able to load/import all 10,000 records/rows.
For the heck of it just also loaded a "Data Table" directly from Excel. Quickly displayed the data and saved it as opposed to the "Collection" which it blew out the Data, after closing the App as expected.
