Hi Everybody, I thought I had somewhat advanced Excel skills but then the following made me feel like I'm back in the beginners' group: Usually people ask here how to achieve something in Excel or VBA. I actually have the answer but I would like to understand it. This morning, I needed a quick way to scrap all non-numeric characters out of the contents of a cell. I wrote a quick VBA function that did the job. Then I started to get curious if Excel offers any worksheet function that would have done this job for me. I learned that this doesn't exist but that the following (data cell is A1 and you'd paste this into B2) =IF(A1="","",SUMPRODUCT(MID(0&A1,LARGE(INDEX(ISNUMBER(--MID(A1,ROW($1:$25),1))*ROW($1:$25),0),ROW($1:$25))+1,1)*10^ROW($1:$25)/10)) does exactly what I'm trying to do. Granted, it's a bit more complex than a VBA macro but I'd still like to understand exactly what this line above does. I tried to decipher it but didn't have much success. Can anybody enlighten me? Maybe step by step? Thanks in advance. Appreciate all your help I get on this board. Christoph
