Using JMP 16.2 on Windows 11 I created a spreadsheet
![txnelson_0-1725304982449.png txnelson_0-1725304982449.png](/t5/image/serverpage/image-id/67796iAE103706A688B745/image-size/medium?v=v2&px=400)
With the A1 value (Header) merged and centered across A1-B1.
Using the Excel Wizard, I simply specified the Column Headers starting in row 1 and the Number of rows with column headers as 2 and finally the Data Starts on row 3

Clicking on the Import button I got

I have attached the Excel file. Try using it and see if you get what I got.
