How to extract text before the last in excel formula

Question

I'm working on a method to extract text before the final comma.

for instance:

Say the following is in Cell A1: "A100, B100, C100, D100." On Cell B1, I need a formula that outputs the value "C100."

Although I was able to create two formulas that fall short in this particular area, I believe a small modification could work.

1st Formula will return the value after the last comma i.e. "D100"

=MID(A1,FIND(CHAR(1),SUBSTITUTE(A1," ",CHAR(1),LEN(A1)-LEN(SUBSTITUTE(A1," ",""))))+1,LEN(A1))

2nd Formula will return everything before the last comma i.e. "A100, B100, C100"

=IFERROR(LEFT(A1,FIND("=",SUBSTITUTE(A1,",","=",LEN(A1)-LEN(SUBSTITUTE(A1,",",""))))-1),"")

Does anyone know what adjustment is needed to get "C100"?

Using FILTERXML()

---

• Formula used in cell B1

=FILTERXML("<m><b>"&SUBSTITUTE(A1,", ","</b><b>")&"</b></m>","//b[last()-1]")

You can read more on FILTERXML() a thoroughly researched and examples shown by JvdV Sir.

You can try this as well,

• Formula used in cell C1

=TRIM(MID(SUBSTITUTE(A1,", ",REPT(" ",100)),(LEN(A1)-LEN(SUBSTITUTE(A1,",","")))*100-99,100))

One more way using of TEXTSPLIT()

=INDEX(TEXTSPLIT(A1,,", "),LEN(A1)-LEN(SUBSTITUTE(A1,",","")))
