Trying to find MS Excel Wilcoxon Rank Sum test example

#1
I am a pharmacy student doing a 4th year (final year) Capstone Research Project. I am attempting to run my data utilizing a Wilcoxon Rank Sum Test on MS Excel. I was wondering if anyone had any ideas of a good tutorial on how to do that?

I've searched YouTube but it was not helpful in regards to my specific set of data. Its really a simple analysis of Pre/post survey answers of 5 questions. The participants were anonymous for both Pre and Post so i'm running it as independent (unpaired).

Was wondering if anyone knew a good free or cheap program that runs a wilcoxon rank sum?

I would so greatly appreciate it.
