Create an iOS spreadsheet file that is readable by both Excel and Numbers

Question

I need to create an iOS spreadsheet file that can be read by both Excel and Numbers. The CSV file is insufficient because it does not allow multiple sheets and / or formatting.

Which format will work best? And is there a library / framework that I could use to create a file in this format?

Answer 1

Create a Google Docs Docs table . Google Data Objective-C Client Library . Then you can import this into Excel / Numbers.
