5 Simple Ways To Convert Month Names To Numbers In Excel

When working with dates in Excel, you might find yourself needing to convert month names (like "January," "February," etc.) into their corresponding numbers (1, 2, 3, etc.). This is especially helpful for data analysis, sorting, or when you want to perform calculations based on the month. In this blog post, we’re going to explore 5 simple ways to convert month names to numbers in Excel, providing practical examples and addressing common mistakes you might encounter.

Method 1: Using the MONTH Function

One of the simplest methods to convert month names to numbers is to use the MONTH function along with the DATEVALUE function. Here's how:

1. Enter the Month Name: In cell A1, type "January".
2. Use the Formula: In cell B1, enter the formula:

   =MONTH(DATEVALUE(A1 & " 1"))
   

3. Press Enter: This will return 1, which corresponds to January.

Example:

This formula takes the month name and treats it as part of a date (adding "1" to indicate the first day of the month), and then extracts the month number from that date.

📅 Pro Tip: To convert multiple month names at once, drag the formula down the column!

Method 2: Using VLOOKUP

You can also use the VLOOKUP function to match month names to their respective numbers.

1. Create a Reference Table: In cells D1:E12, set up a small table like this:

2. Use the VLOOKUP Formula: In cell B1, enter:

   =VLOOKUP(A1, D1:E12, 2, FALSE)
   

3. Press Enter: This will return 1 if A1 is "January".

📊 Pro Tip: Make sure your month names in the lookup table exactly match the entries in column A to avoid errors!

Method 3: Using IF Statements

Another approach is to use a nested IF statement. This method can be cumbersome for all twelve months but is a useful exercise to understand conditionals.

1. Enter Month Name: In cell A1, type "March".
2. Use the IF Formula: In cell B1, enter:

   =IF(A1="January", 1, IF(A1="February", 2, IF(A1="March", 3, IF(A1="April", 4, IF(A1="May", 5, IF(A1="June", 6, IF(A1="July", 7, IF(A1="August", 8, IF(A1="September", 9, IF(A1="October", 10, IF(A1="November", 11, IF(A1="December", 12, "Invalid Month")))))))))))))
   

3. Press Enter: If A1 is "March", it will return 3.

📋 Pro Tip: This method is less efficient for large datasets, but it helps practice nested functions!

Method 4: Using Text to Columns Feature

Excel's Text to Columns feature can also help in converting month names to numbers in bulk. This is useful if you have a column full of month names.

1. Select the Column: Highlight the column with month names.
2. Go to Data Tab: Click on the 'Data' tab in the Ribbon.
3. Choose Text to Columns: Click 'Text to Columns' > Choose 'Delimited' > Click 'Next'.
4. Choose Delimiters: Click 'Finish'. This action will split the month names if they are in a single cell but we can also convert them at this stage using a helper column.

After this step, use the previous methods to convert the month names in the new column.

🧩 Pro Tip: The Text to Columns feature is ideal for larger datasets and can be combined with other methods!

Method 5: Utilizing Array Formulas

If you're using Excel 365 or Excel 2021, you can take advantage of dynamic arrays and make the process simpler.

1. Enter the Formula: In cell B1, use:

   =MATCH(A1, {"January","February","March","April","May","June","July","August","September","October","November","December"}, 0)
   

2. Press Enter: The result will be the corresponding month number.

✨ Pro Tip: This method is concise and efficient for quick conversions!

Common Mistakes to Avoid

When converting month names to numbers, it's easy to make mistakes. Here are some common pitfalls:

• Spelling Errors: Ensure the month names are spelled correctly. An error will lead to a #N/A error in lookup functions.
• Case Sensitivity: Excel's functions like VLOOKUP are case-insensitive, but if you're using exact matches in functions, ensure they match in casing.
• Extra Spaces: Leading or trailing spaces in your month names can cause errors. Always use the TRIM function if you're not sure.
• Not Using Absolute References: When creating a reference table and dragging formulas, be cautious to use absolute references for the lookup table.
