How to extract nth word from text string
This post will guide you how to extract the nth word from a text string in excel. How do I get the nth word from text string in a cell using excel formula. How to write a User Defined Function to extract nth word from text.
Extract nth word
If you want to extract the nth word from a text string in a single cell, you can create an excel formula based on the TRIM function, the MID function, the SUBSTITUTE function, the REPT function and the LEN function.
You can use the SUBSTITUTE function replaces each space character with a number of space characters returned by the REPT function. The number of space characters should be equal to the overall length of the original text in cell. So you also need to use the LEN function to combine with the REPT function to create those spaces. Then you can use the MID function to extract the nth word and the starting position can get from the formula (N1)*LEN(B1)+1 , and the num_chars should be equal to the length of the original text.
Assuming that you want to extract the third word from text string in Cell B1, you can write down the following excel formula:
=TRIM(MID(SUBSTITUTE(B1," ", REPT(" ",LEN(B1))), (31)*LEN(B1) +1, LEN(B1)))
Let’s see how this formula works:
=REPT(” “,LEN(B1))
This formula will return a new text string that contain a number of the space characters and the number of space character is equal to the length of the original text string in Cell B1. Then it goes into the SUBSTITUTE function as its new_text argument.
=SUBSTITUTE(B1,” “, REPT(” “,LEN(B1)))
This formula replace each space character with new_text that returned by the REPT function. Then it goes into the MID function as its Text argument.
=(31)*LEN(B1) +1
This formula returns the starting position of the third word from the text in Cell B1. Then it passed into the MID function as its start_num argument.
=MID(SUBSTITUTE(B1,” “, REPT(” “,LEN(B1))), (31)*LEN(B1) +1, LEN(B1))
The both Text and start_num arguments are returned by the above two formula, so this formula extracts the third word from the text in Cell B1.
=TRIM()
The TRIM function removes all extra space characters and just leave only one between words.
Extract Nth word with User Defined Function
You can also write a User Defined Function to extract the nth word from the text string in a cell in Excel VBA:
1# click on “Visual Basic” command under DEVELOPER Tab.
2# then the “Visual Basic Editor” window will appear.
3# click “Insert” >”Module” to create a new module
4# paste the below VBA code into the code window. Then clicking “Save” button.
Function GetNthWord(Source As String, Position As Integer) Dim arr() As String arr = VBA.Split(Source, " ") xCount = UBound(arr) If xCount < 1 Or (Position  1) > xCount Or Position < 0 Then GetNthWord = "" Else GetNthWord = arr(Position  1) End If End Function
5# back to the current worksheet, then enter the below formula in Cell C1:
