Converting or Viewing Mac files on PC from a WD MyBook for Mac

I have a WD My Book for Mac 1T and it is formatted for a Mac. However, my Mac motherboard went out and now im using a PC for now. How do I view my files that are on my WD drive on a PC if it is formatted for a Mac, without losing my files?

I don’t know much about Macs but saw this recommended a couple of times Other than that there are only paid programs like MacDrive
