#Convert Excel files to PDF

There are tons of solutions out there that will "automate" the conversion of Microsoft Office files to PDF. Unfortunately, many of them are bloated with spammy advertisements or will watermark your documents or any number of other unfriendly results.

If all that you really need to do is simply loop over a directory of say 30 or 300 or 3,000 Microsoft Office files and convert them each 1 by 1 into PDF's then a very lightweight solution can be found here.

Thanks to a conversation on Stack Overflow
