You can use the following basic syntax to count the number of used columns in an Excel sheet using VBA:
Sub CountColumns()
Range("A10") = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
End Sub
This particular example counts the number of used columns in the sheet called Sheet1 and displays the result in cell A10.
If you would instead like to display the column count in a message box, you can use the following syntax:
Sub CountColumns()
Dim LastCol As Long
LastCol = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
MsgBox "Column Count: " & LastCol
End Sub
The following examples shows how to use each of these methods in practice with the following dataset in Excel that contains information about various basketball players:
Example 1: Count Used Columns in VBA and Display Results in Cell
Suppose we would like to count the number of used columns and output the results in a specific cell.
We can create the following macro to do so:
Sub CountColumns()
Range("A10") = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
End Sub
When we run this macro, we receive the following output:
Notice that cell A10 contains a value of 4.
This tells us that the there are 4 used columns.
Example 2: Count Used Columns in VBA and Display Results in Message Box
Suppose we would instead like to count the number of used columns and output the results in a message box.
We can create the following macro to do so:
Sub CountColumns()
Dim LastCol As Long
LastCol = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
MsgBox "Column Count: " & LastCol
End Sub
When we run this macro, we receive the following output:
The message box tells us that there are 4 used columns.
Note: If there are empty columns followed by columns with data, VBA will count the empty columns as “used” in the calculation.
