How to Stack Data from Multiple Columns into One Column in Excel
In previous article, I have shown you the method to split data from one long column to multiple columns by VBA and Index function. This time if we want to stack data from multiple columns to one column, how can we do? Actually, we can still use VBA script or formula of Index function to make it come true. This article will introduce you the two methods. After reading the article below, you will find the two ways are verify simple and convenient to operate in excel.
For example, see the initial table below:
And we want reverse data into one column and make it looks like:
Now we can follow below two methods to make it possible.
Method 1: Stack Data in Multiple Columns into One Column by Formula
Step 1: Select range A1 to F2 (you want to do stack), in Name Box, enter a valid name like Range, then click Enter.
Step 2: In any cell you want to locate the first cell of destination column, enter the formula =INDEX(Range,1+INT((ROW(A1)1)/COLUMNS(Range)),MOD(ROW(A1)1+COLUMNS(Range),COLUMNS(Range))+1).
Please be aware that you have to replace ‘Range’ in this formula to your defined name in Name Box.
Step 3: Click Enter. Verify that ‘ID’ (the value in the first cell of selected range) is displayed properly.
Step 4: Drag the fill handle to fill I column. Verify that data in previous initial location is reversed to one column properly.
Note:
If you drag the fill handle to cells extend selected range cell number, error will be displayed in redundant cell.
Method 2: Stack Data in Multiple Columns into One Column by VBA
Step 1: On current visible worksheet, right click on sheet name tab to load Sheet management menu. Select View Code, Microsoft Visual Basic for Applications window pops up.
Or you can enter Microsoft Visual Basic for Applications window via Developer>Visual Basic.
Step 2: In Microsoft Visual Basic for Applications window, click Insert>Module, enter below code in Module1:
Sub StackDataToOneColumn() Dim Rng1 As Range, Rng2 As Range, Rng As Range Dim RowIndex As Integer Set Rng1 = Application.Selection Set Rng1 = Application.InputBox("Select Range:", "StackDataToOneColumn", Rng1.Address, Type:=8) Set Rng2 = Application.InputBox("Destination Column:", "StackDataToOneColumn", Type:=8) RowIndex = 0 Application.ScreenUpdating = False For Each Rng In Rng1.Rows Rng.Copy Rng2.Offset(RowIndex, 0).PasteSpecial Paste:=xlPasteAll, Transpose:=True RowIndex = RowIndex + Rng.Columns.Count Next Application.CutCopyMode = False Application.ScreenUpdating = True End Sub
Step 3: Save the codes, see screenshot below. And then quit Microsoft Visual Basic for Applications.
Step 4: Click Developer>Macros to run Macro. Select ‘StackDataToOneColumn’ and click Run.
Step 5: Stack Data to One Column dialog pops up. Enter Select Range $A$1:$F$2. Click OK. In this step you can select the range you want to do stack.
Step 6: On Stack Data to One Column, enter Destination Column $I$1. Click OK. In this step you can select the first cell from destination range you want to save data.
Step 7: Click OK and check the result. Verify that data is displayed in one column properly. The behavior is as same as the result in method 1 step# 4.
