Hi @Hemant2 ,

  1. Use the “Read Range” activity to read the Excel file and store the data in a variable named Input_DT.
  2. Create a variable called Column_List with the data type System.Collections.Generic.List<String>. This variable will hold the data from the specified column.
  3. Use an “Assign” activity to set the value of Column_List using the following LINQ query:
(From row In Input_DT.AsEnumerable() Select Convert.Tostring(row("column_Name")) ).ToList()

Explanation of the LINQ Query

The LINQ query (From row In Input_DT.AsEnumerable() Select Convert.ToString(row("column_Name"))).ToList() performs the following steps:

  • From row In Input_DT.AsEnumerable(): Iterates over each row in the DataTable Input_DT.
  • Select Convert.ToString(row("column_Name")): For each row, it selects the value of the specified column (column_Name) and converts it to a string.
  • .ToList(): Converts the selected values into a list of strings.

You can simply use the below steps… @Hemant2

Check the below steps:
→ Use the Read range workbook activity to read the excel and store in a datatable.
→ Use assign activity to write the LinQ Expression,

dt.asenumerable().select(Function(X) X("Column name").toString).tolist()


Hi @Hemant2

Read the Excel (Output=dt)
Use For each Row
Inside the loop create a list variable called columnList (Initialize the list also)
Use assign activity
columnList= dt.AsEnumerable() Select row(“YourColumnName”).ToString()).ToList()

Hope this helps you
