I'm always asked to take Word documents, Excel spreadsheets, or other items and turn then into a PDF file. Well there is no mystery to this and anyone with a Mac can do it.
Just open the document and choose PRINT
When the print dialog box appears, ignore all those print commands and go right to the bottom to the PDF button.
When you click that button, you'll get a pop-up menu. The first choice is to "Save as PDF..." Select that.
You'll be asked to title your new document. And just like magic, you too have created a PDF document!
