Hey @Chippy_Kolot

Try adding {} empty array instead of Nothing

I tried but getting error “Array initializer has too few dimensions.value of type 2d array of string cannot be converted to id array of object”.

excel
Here serial no is taking from zero.but it has to start from one…

@Nithinkrishna If you create a column in data table with type Int32 it will take starting value as 0. Why don’t you try passing the counter variable which has Slno in add data row activity ( along with employee name)

Hey @Chippy_Kolot

You can set it but not through activity as it doesn’t have the prop.

Kindly ref this to write in code - DataColumn.AutoIncrement Property (System.Data) | Microsoft Docs

Hope this helps.

Ya I got.Thank you.
1.In datatable I created a column named serialno with datatype Int32.
2.After add datarow activity I created a variable in assign activity.(Serialno=Serialno+1).
3.Passed this variable to the add data row activity.
