I've been working with some folks on a project who are visually impaired and I've been tasked with creating some documents that would best be presented in matrix charts, tables, etc. They're all tech savvy, but I'm wondering whether it's better/easier to prepare these charts in excel or word? Are both equally accessible? Should I avoid charts and aim for bulleted lists instead?

(Feeling naive and invasive, but I just want to start these things in the best format so I don't have to re-do them later on.)

Thanks!
