Sum entire column in Excel

I have sheet, How to sum entire column in Excel

Sum entire Price column





Try this:

input_dt.AsEnumerable.Sum(Function(x) CDbl(x("Price").ToString.Trim))

Hi @priyachennuru789

→ Use the Read range workbook activity to read the excel and store in a datatable called inputDataTableVariable.
→ Use the assign activity to write the below LINQ Expression, Create a datatable datatype variable called Output_dt.

- Assign -> Output_dt = Input_dt.DefaultView.ToTable(False, "Category","Price")

→ Then drag and drop one more assign activity and give the below LINQ Expression,

- Assign -> Output_dt = (From row In Input_dt.AsEnumerable()
                         Group row By Category = row.Field(Of String)("Category") Into Group
                         Let PriceSum = Group.Sum(Function(x) If(TypeOf x("Price") Is String,
                                           Double.Parse(DirectCast(x("Price"), String).Replace(",", ".")),
                                           DirectCast(x("Price"), Double)))
                         Select Output_dt.LoadDataRow(New Object() {Category, PriceSum}, False)

→ Then use the write range workbook activity to write the outputDataTableVariable to the excel file.

Check the below output file,

Hope it helps!!


' Arguments
' inputDataTable - Input DataTable
' outputDataTable - Output DataTable (Argument: Out)

' Ensure the outputDataTable has the correct structure
outputDataTable = New DataTable()
outputDataTable.Columns.Add("Category", GetType(String))
outputDataTable.Columns.Add("Price", GetType(Decimal))

' Perform the grouping and summing using LINQ
Dim groupedData = From row In inputDataTable.AsEnumerable()
                  Group row By category = row.Field(Of String)("Category") Into categoryGroup = Group
                  Select New With {
                      .Category = category,
                      .TotalPrice = categoryGroup.Sum(Function(r) If(IsNumeric(r.Field(Of String)("Price")), Convert.ToDecimal(r.Field(Of String)("Price")), 0))

' Populate the outputDataTable with the grouped data
For Each item In groupedData
    Dim newRow As DataRow = outputDataTable.NewRow()
    newRow("Category") = item.Category
    newRow("Price") = item.TotalPrice

Put this in Invoke code
