Excel Column to Number: Understanding the Conversion Process

Are you struggling with converting Excel columns to numbers? Do you find it difficult to work with alphanumeric data? You’re not alone. Many users struggle with this issue, especially those who work with large data sets.

In this article, we’ll discuss the process of converting Excel columns to numbers. We’ll cover the basics of the conversion process and provide step-by-step instructions to help you make the switch. So, let’s get started!



Understanding Excel Columns

Before we dive into the conversion process, let’s take a moment to understand what Excel columns are. Excel columns are identified by letters, such as A, B, C, etc. These letters represent the column headers and are used to organize and reference data within a worksheet.

Each column contains cells, which are identified by numbers. For example, cell A1 is in the first column and first row of a worksheet. Similarly, cell B1 is in the second column and first row of a worksheet.

Why Convert Excel Columns to Numbers?

Excel columns are great for organizing data, but they can be difficult to work with when you need to perform calculations or sort data. For example, if you have a column containing alphanumeric data, such as “A1,” “B2,” etc., you can’t easily calculate that data.

By converting Excel columns to numbers, you can make it easier to perform calculations and sort data. For example, if you have a column that contains alphanumeric data, you can convert that data to numbers and then sort the column in ascending or descending order.

Excel Column to Number: The Conversion Process

Now that we’ve covered the basics of Excel columns, let’s dive into the conversion process. Converting Excel columns to numbers is a straightforward process that can be done in a few simple steps.

Here’s how to do it:

  1. Select the column that you want to convert.
  2. Right-click on the selected column and choose “Format Cells” from the context menu.
  3. In the “Format Cells” dialog box, select the “Number” tab.
  4. Select “Number” from the list of categories.
  5. Set the number of decimal places that you want to display (if any).
  6. Click “OK” to apply the formatting.

That’s it! Your Excel column has now been converted to numbers.

Tips for Converting Excel Columns to Numbers

While the conversion process is simple, there are a few tips that can help make the process smoother:

  • Be sure to select the entire column before formatting. You may not get the desired results if you only select a few cells.
  • Check your formatting before applying it to a large data set. It’s always a good idea to test your formatting on a small set of data before applying it to a larger set.
  • Use the “General” format for data that may contain both numbers and text. The “General” format will display data as numbers when possible but will also display text when necessary.

Understanding Excel Column Letters and Numbers

Before we dive into the methods to convert Excel column letters to numbers, it’s essential to understand the relationship between column letters and numbers. In Excel, each column is identified by a letter or a combination of letters. The first column is labeled “A,” the second column is labeled “B,” and so on. After the letter “Z,” the columns are labeled using two letters, starting with “AA,” “AB,” “AC,” and so on.

It’s also essential to understand that each column has a corresponding numeric value. For example, column A has a numeric value of 1; column B has a numeric value of 2, and so on. The numeric value of a column is used in Excel formulas and functions.

Methods to Convert Excel Column Letters to Numbers

There are several methods to convert Excel column letters to numbers, and we’ll explore some of the most common ones in this section.

Method 1: Using the COLUMN Function

The COLUMN function in Excel returns the column number of a reference. You can use this function to return the column number of a specific cell reference or column letter. To use the COLUMN function to convert a column letter to a number, follow these steps:

  1. Select the cell where you want to display the column number.
  2. Enter the following formula: =COLUMN(A1), where A1 is the cell reference of the column letter you want to convert.
  3. Press Enter to complete the formula. The cell will display the numeric value of the column letter.

Method 2: Using the ASCII Function

The ASCII function in Excel returns the ASCII code of a specific character. Since each letter has a unique ASCII code, you can use the ASCII function to convert a column letter to its numeric value. To use the ASCII function to convert a column letter to a number, follow these steps:

  1. Select the cell where you want to display the column number.
  2. Enter the following formula: =CODE(A1)-64, where A1 is the cell reference of the column letter you want to convert.
  3. Press Enter to complete the formula. The cell will display the numeric value of the column letter.

Method 3: Using Custom VBA Function

If you frequently need to convert column letters to numbers, you can create a custom VBA function to automate the process. To create a custom VBA function, follow these steps:

  1. Press ALT + F11 to open the VBA editor.
  2. Click Insert > Module to create a new module.
  3. Enter the following code:
Function ColNum(strCol As String) As Integer
ColNum = Range(strCol & "1").Column
End Function
  1. Save the module and close the VBA editor.
  2. In your worksheet, enter the following formula: =ColNum(“A”), where “A” is the column letter you want to convert.
  3. Press Enter to complete the formula. The cell will display the numeric value of the column letter.

How To Combine Two Columns In Excel?

Combining two columns in Excel can be a useful way to streamline your data and make it more accessible. To do this, you can use the CONCATENATE function or the ampersand (&) symbol. First, select the cell where you want to place the combined data. Then, enter the CONCATENATE function or the ampersand symbol, followed by the cell references for the two columns you want to combine. Add any desired separators, such as spaces or commas, between the two columns to make the combined data more readable. This simple process can help you save time and increase efficiency when working with large Excel data sets.

Conclusion

Converting Excel column letters to numbers is a common problem that many users face. This article explored various methods to convert column letters to numbers quickly and easily, including using the COLUMN function, the ASCII function, and creating a custom VBA function.

These methods can save you time and effort when working with large data sets or creating macros. However, it’s essential to understand the relationship between column letters and numbers in Excel and choose the best method for your specific needs.

If you’re new to Excel or need to brush up on your skills, consider taking an online course or watching tutorials to learn more. With a little practice, you’ll be converting Excel column letters to numbers like a pro in no time.
