→ Use the Read range workbook activity to read the excel and store in a datatable called dt_Input.
→ Then take an assign activity, and you can use LINQ Expression,
- Assign -> dt_Output = (From row In dt_Input.AsEnumerable()
Where System.Text.RegularExpressions.Regex.IsMatch(row("Date").ToString(), "\d+/\d+/\d+")
Select row).CopyToDataTable()
→ Then use the Write range workbook activity to write the dt_Output to excel.
Hope it helps!!
