Excel Column Number from Column Name: The Easy Guide

Have you ever found yourself in a situation where you need to convert a column name in Excel to its corresponding column number? 🤔 Don't worry, you're not alone! This is a common problem that many Excel users encounter. Whether it's for data analysis, VBA programming, or simply understanding the structure of your spreadsheet, knowing how to effortlessly perform this conversion is a handy skill to have. In this blog post, we'll explore common issues, provide easy solutions, and empower you with the knowledge to tackle this problem head-on. 💪💻

The Problem: Converting Column Names to Column Numbers

Let's start by understanding the problem at hand. Imagine you have an Excel worksheet with column headers ranging from A to ZZ. You want to retrieve the corresponding column number for a given column name. For example, if the column name is "C", you would expect the column number to be 3. The challenge lies in finding a simple and efficient solution to this problem. 🤯

The Solution: A Simple Excel Macro

To tackle this problem, we'll leverage the power of Excel macros. Excel macros are a set of commands and instructions that can automate repetitive tasks, saving you time and effort. Here's a step-by-step solution to obtaining the column number from a column name using an Excel macro:

1. Open your Excel workbook and press Alt + F11 to open the Visual Basic for Applications (VBA) editor.

2. In the VBA editor, insert a new module by clicking Insert > Module.

3. In the new module, copy and paste the following macro code:

Function ColumnNumber(columnName As String) As Long
    Dim columnLetter As String
    Dim i As Integer
    
    columnLetter = UCase(columnName)
    ColumnNumber = 0
    
    For i = 1 To Len(columnLetter)
        ColumnNumber = ColumnNumber * 26 + (Asc(Mid(columnLetter, i, 1)) - 64)
    Next i
End Function

1. Close the VBA editor.

2. Now, back in Excel, you can use the ColumnNumber function in any cell. For example, if you want to convert the column name in cell A1, you would type =ColumnNumber(A1) in another cell to get the corresponding column number.

That's it! 🎉 You now have a handy macro at your disposal that can convert column names to column numbers effortlessly.

Bonus Tip: Enhancing the Macro

The above macro works perfectly for column names from A to ZZ. However, what if you're working with column names beyond ZZ? Fear not! We can enhance the macro to handle larger column name ranges as well. Simply modify the For statement in the macro as shown below:

For i = 1 To Len(columnLetter)
    ColumnNumber = ColumnNumber * 26 + (Asc(Mid(columnLetter, i, 1)) - 64)
Next i

With this enhancement, you can now convert column names up to three characters long. Just keep in mind that the maximum Excel column name length is three characters.
