You can always check this topic where I shared my results with every Preserve Format configuration on the Date Format.
There is also a Workflow called Filtering that examples the filtering with DataTable from Read Range Workbook where both Preserve Format throws System.Object DataType but the filtering only works when the configuration is false. I think you already addressed this issue on your last reply, but I’m not sure if I got you quite alright. Do you mean that when Preserve Format is True the whole column DataType is Object but every value individually is treated as a string? where in false are treated as objects? If that’s so, you can ignore that workflow
Thank you once again
