Hello.

Sorry for reposting topic, but I have failed to find out decision for my situation.

I get some data from xls and have to split it to several files.
To divide I use Filter DataTable activity that does not work correctly, because there is something wrong in column type of the first column. The first column is based on Line numbers.

I found out the similar topic How to change the data type of a column in data table , but I failed to apply presented recommendations. (CopyToDataTable is not a member of System.Array)

What’s wrong I am doing?

Files in attach.

Main.xaml (13.4 KB)

Thanks in advance
