Hi,
thanks for your report unfortunately I will need more information to be able to help you. I tried several Excel files and compared them without problem. Also I tried use DCP file in Automation and I got same result.
Can you provide me what TDP version do you have? What is your Excel version and do you have problem with all excel files (can you create some sample Excel files and try it )? We need to know if problem is related to Excel version / data or if there is some problem in TDP functionality.
Thanks
Filip
