At the core, this formula uses the MID function to extract characters starting at the second to last space. The MID function takes 3 arguments: the text to work with, the starting position, and the number of characters to extract.
The text comes from column B, and the number of characters can be any large number that will ensure the last two words are extracted. The challenge is to determine the starting position, which is just after the second to last space. The clever work is done primarily with the SUBSTITUTE function, which has an optional argument called instance number. This feature is used to replace the second to last space in the text with the "@" character, which is then located with the FIND function.
Working from the inside out, the snippet below figures out how many spaces are in the text total, from which 1 is subtracted.
The result of FIND is 17, to which 1 is added to get 18. This is the starting position, and goes into the MID function as the second argument. For simplicity, the number of characters to extract is hardcoded as 100. This number is arbitrary and can be adjusted to fit the situation.
Extract last N words from cell
This formula can be generalized to extract the last N words from a cell by replacing the hardcoded 1 in the example with (N-1). In addition, if you are extracting many words, you may want to replace the hardcoded argument in MID, 100, with a larger number. To guarantee you the number is large enough, you could simply use the LEN function as follows:
If you need extract the last name from a full name, you can do so with this rather complex formula that uses several functions. In the generic form of the formula (above), name is a full name, with a space separating the first name from other parts...
If you need to get the nth word in a text string (i.e. a sentence, phrase, or paragraph) you can so with a clever (and intimidating) formula that combines 5 Excel functions: TRIM, MID, SUBSTITUTE, REPT, and LEN. How this formula works At the core,...
To find the nth occurence of a character in a text string, you can use a formula based on the FIND and SUBSTITUTE functions. In the example shown, the formula in D5 is: = FIND ( CHAR ( 160 ), SUBSTITUTE ( B5 , "@" , CHAR ( 160 ), C5 )) How...
To get the position of the 2nd, 3rd, 4th, etc. instance of a specific character inside a text string, you can use the FIND and SUBSTITUTE functions. In the example shown, the formula in E4 is: = FIND ( "~" , SUBSTITUTE ( B4 , "x...
The Excel SUBSTITUTE function replaces text in a given string by matching. For example =SUBSTITUTE("952-455-7865","-","") returns "9524557865"; the dash is stripped. SUBSTITUTE is case-sensitive and does not support wildcards.
The Excel FIND function returns the position (as a number) of one text string inside another. When the text is not found, FIND returns a #VALUE error.
