Converting xls(x) with formulas to PDF

I'm not sure if this is an Acrobat question or an Office question but I'll ask it here anyway. I have these multi-page order forms that I need many many working formulas on each page of the pdf. In the past I've done all of the formulas in Acrobat but because of the amount needed, it's so tedious and extremely time consuming. Is there an easy way to convert an xls/xlsx document with formulas into a pdf that keeps everything in place including layout and more importantly the formulas? OR if anyone has a different method I'm all ears. I've tried using the form wizard but it doesn't really speed things up.

Any information would be appreciated.

thanks!
