I have Open Office in my computer. i think it is better than Microsoft, It will convert files you need as well, As long as you are doing this for your personal files and not got a business, its free! I don't know what they charge for the service if this is a business. Hope this helps. WD
Hello Wallaby Dan, thank you for your recommendation and link, very much appreciated.
I have heard of Open Office before but have never investigated it, I might just have a look now.
With regard to my current problem, I have now got it sorted. I found that if I downloaded iCloud for Windows 10 I could drag and drop each file into the Pages or Numbers sections and convert them from there. It worked well.
