Merge datatable - column data type does not mach


I am merging 2 datatables (one from excel and one from data scraping). I get the following error:

How do I check the datatypes of the columns of both datatables? And how do I change it?


further clarification:
The datatype of the column in dt1 is “object” and the datatype of the column in dt2 is “string”.
I need these two to match so that I can merge the two datatables.

Hello Yannip,

First write data scraping datatable to excel and read that excel to create another datatable and then start merging them
