Creation of A3 size posters

I need boring excel spreadsheets put into a illustrative A3 posters. The information is on 43 tabs on excel. The project is to copy paste the questions and make the poster more appealing with some infographics or clip art or illustrations.
No fancy creations of graphics or anything like that. You can use canva or Venngage program. I don’t mind. Just need the information to be read so the poster must be appealing.
