How to create an excel with an object in Android and send it via Email

On my app I have an object of records, let's say I have todo a quiz with more than 5 guys, so I can then get the results of all of them and I have an Object with all of that information, is it possible to convert this Object to an Excel file? For example :

|---------------------|------------------|
|        Quiz         |     Question 1   |...
|---------------------|------------------|
|      Quiz Name      |    What's 1+1    |...
|---------------------|------------------|

Something like this, to know each user what answered and its score, all of it I have it on my Object.

And then if I can send it via Mail the .xls or whatever format.

EDIT

For example I'll need Quiz name and if I can add more about this quiz is ok, but then I need to add all of users have asked this quiz (another object from api) so I could get the name and the score.
