PDF file/s transferred to a word doc

Hello 🙂 My MacBook crashed this week and I’ve lost 2 important files. I have them as a PDF but need them converted into a word doc so I can make some changes. Can anyone assist with this. ? I’m using an older version of word too since someone has kindly lent me MacBook. So I need to make sure it’ll convert ok on the computer I’m using. I need the job done by early afternoon tomorrow - Sat 7th Nov. Thanking you!
