# Convert Month Name to Number in Excel

In some situations, you may have the month name that you want to convert into the month number so that it can be used further in calculations.

While there is no built-in function to do this in Excel, it’s pretty easy with simple formula workarounds.

In this article, I will show you a couple of methods for converting month names to numbers in Excel.

So, let’s see how to do this!

This Tutorial Covers:

## Using the MONTH Function

Below, I have a data set where I have month names in column A, and I want to get their month number in column B.

Here is the formula to do this:

`=MONTH("1"&A2)`

The above formula converts the month name into a more recognizable date format for Excel. So January is converted to 1January.

Now, when I use the MONTH function to fetch the month name from this date, it correctly identifies this as January and gives me the month number as 1.

For this to work correctly, you need to ensure that your month name is in a format that Excel can recognize as a date, such as January or Jan.

## Using MATCH Function

Another way to convert the month name to the month number is by using the MATCH function.

In this method, you manually enter all the month names, and then the match function can find the name and give you the corresponding position.

Below, I have a dataset where I have month names in column A, and I want to get their month number in column B:

Below is the formula that will do this:

`=MATCH(A2,{"January","February","March","April","May","June","July","August","September","October","November","December"},0)`

One benefit of this method is that it allows you to rearrange the month names if you want.

For example, if I’m working with the data set where my financial year is from April to March, and I want April to be month 1 and May to be month 2, and so on, I can modify the formula as shown below:

`=MATCH(A2,{"April","May","June","July","August","September","October","November","December","January","February","March"},0)`

## Using VLOOKUP Function

If you need to convert the month name into the corresponding number often in the same workbook, it would be more efficient to create a table with the month name in one column and the number in another column and then use VLOOKUP to fetch the value.

Below, I have month names in column A, and I want to get their month number in column B. I have also created a table (named Table1) that lists all the months and the numbers, as shown below:

Below is the VLOOKUP formula I can use to fetch the month number based on the month’s name:

`=VLOOKUP(A2,Table1,2,0)`

or, if you have the XLOOKUP function, then you can use the below formula as well:

`=XLOOKUP(A2,Table1[Name],Table1[Number],"",0)`

## VBA Custom Function to Convert Month Name to Number

Another way to do this is by creating your own custom function using VBA, and then use that function wherever you want to convert month name into number.

Below is the VBA code that would create a custom function that takes the month name as the input and converts it into the corresponding number.

``````Function MonthNameToNumber(monthName As String) As Integer
Select Case LCase(monthName)
Case "january": MonthNameToNumber = 1
Case "february": MonthNameToNumber = 2
Case "march": MonthNameToNumber = 3
Case "april": MonthNameToNumber = 4
Case "may": MonthNameToNumber = 5
Case "june": MonthNameToNumber = 6
Case "july": MonthNameToNumber = 7
Case "august": MonthNameToNumber = 8
Case "september": MonthNameToNumber = 9
Case "october": MonthNameToNumber = 10
Case "november": MonthNameToNumber = 11
Case "december": MonthNameToNumber = 12
Case Else: MonthNameToNumber = 0 ' Invalid month name
End Select
End Function``````

Below are the steps to use this VBA code in your Excel file:

1. Hold the ALT key and press the F11 key to open the VB editor. Alternatively, you can also click on the Developer tab and then click on the Visual Basic icon to open the VB editor.
2. In the VB editor, click on the Insert option in the menu and then click on Module.
3. In the module code window, copy and paste the above VBA macro code.
4. Click on the save icon in the VB editor and close it.

Now, you can use MonthNameToNumber as any other regular worksheet function in your workbook.

`=MonthNameToNumber(A2)`

These are some of the methods you can use to quickly convert a month’s name into its corresponding month number in Excel.

While the easiest would be to use the MONTH name function, the other methods I’ve covered offer you a little more flexibility if you’re dealing with inconsistent data sets.
