excel – Copy a variable number of values to another spreadsheet

Posted by: admin April 23, 2020 Leave a comment

Questions:

I’m trying to take a range (lets say C:C), go through all the cells with value and paste them in another spreadsheet.

My target is to copy a variable number of values (because I don’t know how many values I would have in C:C) to another sheet, so I have a new range with all the values (where there are no repeated values).

How to code the If statement (for a variable number of values)?

Sub Test_1()
    ' Go through each cells in the range
    Dim rg As Range
    Dim copySheet As Worksheet
    Dim pasteSheet As Worksheet

    Set copySheet = Worksheets("Data")
    Set pasteSheet = Worksheets("Data_storage")

    For Each rg In Worksheets("Data").Range("C:C")

        If rg.Value = "Client 1" Then 'Instead of "Client 1" should be a variable value because "Client 1" will be a repetead value in C:C 
            copySheet.Range("C2").Copy 'Starting the counter in C2
            pasteSheet.cells(Row.Count, 1).End(xlUp).Offset(1, 0).PasteSpecial xlPasteValue
        End If

    Next

End Sub
How to&Answers:

assuming your values in “Data” worksheet:

  • are in column “C”

  • start from row 1, with a “header”

then you can try this code:

Option Explicit

Sub Test_1()
    Dim sourceRng As Range, pasteRng As Range, cell As Range

    Set pasteRng = Worksheets("Data_storage").Range("A1") '<--| set the upper-left cell in "paste" sheet

    With Worksheets("Data") '<--| reference "source" sheet
        Set sourceRng = .Range("D1", .Cells(.Rows.Count, "C").End(xlUp)) '<--| set the "source" range to columns "C:D" from row 1 down to last non empty cell in column "C"
    End With

    With sourceRng '<--| reference "source" range
        .Sort key1:=.Range("a1"), order1:=xlAscending, key2:=.Range("B1"), order2:=xlAscending, header:=xlYes '<--| sort it by its column 1 and then by its column 2
        pasteRng.Resize(.Rows.Count).value = .Resize(, 1).value '<--| paste its column 1 values to "Paste" sheet column 1
        pasteRng.CurrentRegion.RemoveDuplicates Columns:=Array(1) '<--| leave only unique values in "paste" range
        Set pasteRng = pasteRng.Range(pasteRng.Offset(1), pasteRng.End(xlDown)) '<--| skip "paste" range header
        For Each cell In pasteRng '<--| loop through unique values in "paste" range column 1
            .AutoFilter field:=1, Criteria1:=cell.value '<--| filter "source" range column 1 with current unique value
            .Offset(1, 1).Resize(.Rows.Count - 1, 1).SpecialCells(xlCellTypeVisible).Copy '<--| copy "source" range" column 2 filtered cells
            cell.Offset(, 1).PasteSpecial Transpose:=True   '<--| ... and paste/transpose them aside current unique value in "paste" range
        Next cell
        .Parent.AutoFilterMode = False '<--| .. show all rows back...
    End With
End Sub

Answer:

A dictionary can also be useful, especially if you plan more complicated filtering or calculation:

Public Sub CopyUnique(rngSource As Range, rngDestinationFirst As Range)
    If rngSource Is Nothing Or rngSource.Worksheet.UsedRange Is Nothing Then
        Exit Sub
    End If
    Dim dctValues As Scripting.Dictionary: Set dctValues = New Scripting.Dictionary ' Requires Tools > References > Microsoft Scripting Runtime
    Dim rngSourceUsed As Range: Set rngSourceUsed = Application.Intersect(rngSource, rngSource.Worksheet.UsedRange)
    Dim varCell As Variant: For Each varCell In rngSourceUsed.Cells: Dim rngCell As Range: Set rngCell = varCell
        If dctValues.Exists(rngCell.Value) = False Then
            dctValues.Add varCell.Value, varCell.Value ' varCell.Formula may be also interesting depending on the business logic
        End If
    Next varCell
    Dim varValues() As Variant: ReDim varValues(0 To dctValues.Count - 1, 0 To 0)
    Dim i As Long: i = LBound(varValues, 1)
    Dim varValue As Variant: For Each varValue In dctValues.Keys
        varValues(i, 0) = varValue
        i = i + 1
    Next varValue
    rngDestinationFirst.Resize(dctValues.Count, 1).Value = varValues
End Sub

Public Sub TestCopyUnique()
    CopyUnique ActiveSheet.Range("C:C"), Workbooks.Add(xlWBATWorksheet).Worksheets(1).Range("A1")
End Sub

Answer:

If you don’t want to sort them, you can record a macro of something like this:

  • Select column C

  • Home ➤ Find & Select ➤ Constants

  • Copy and paste the selection to the other sheet

  • Data ➤ Remove Duplicates

P.S. I used #3 from here :]
