Saving to iCloud

Confused!

I have an excel spreadsheet I created which is a database of deductions for my income tax of 2014. I work with it on my Macbook as an excel file. I saved it to iCloud Drive. However, at one point I had uploaded it to iCloud "Numbers" and it changed to a "Numbers" format. Now, when I edit the file on my Macbook I don't see any way to seamlessly change the file resting in "Numbers". I see that I can continuously upload the changes into iCloud Drive. Can I sync the file both into iCloud Drive and "Numbers"? Without that capability I don't see the changes in my iPad or iPhone "Numbers" file.
