Are Both the ExcelDefaultData and eligibleExcelData are both of DataTable Types.


Kindly add this assembly reference to your main.xaml by opening that in notepad and then try mentioning copytodatatable once on opening studio

Also ensure that eligibleExcelData is variable of type System.Data.Datatable

as i can see in your excel and workflow screenshots the column names are different.

Kindly check whether the column names are matching in both workflow and excel.

For this, Instead of using .Select().CopyToDataTable and assigning it to new DataTable Variable use Filter Activity.

It is fair and simple.


this is already present in the file.

Aaha I can see like the column name mentioned in filter is not correct
It should be Eligible for hike but was mentioned as “Eligibility for hike**
Kindly check that once

And if the assembly reference is mentioned in the xaml file then the expression be like
Datatable = Datatable.Select(“[yourcolumnname] = ‘yourvalue’ “).CopyToDatatable()
