Corona and Excel

Hello, I need read and write some information from Excel files, is it posible with Corona?

reading xls files? good luck there as their format is propriety (just open an xls in sublime to see what I mean).

reading csv files? yeah that is real easy.

Thank you, what about writing? For CSV is it easy too?

And what about Access? I just need read some answers from any DB and write to other DB.

Both Excel and Access can output CSV files… do read their respective documentation
