Want to take your spreadsheets, documents, and presentations from Dropbox and start using them with Apple’s iWork suite of Numbers, Pages, and Keynote, and store them in iCloud? Luckily, both Dropbox and Apple make it easy to do. Here’s how!
1、Launch the Dropbox app on your iPhone or iPad, navigate to the file you want to open in Pages, Keynote, or Numbers, and open it inside of Dropbox.
2、Tap on the Share button in the bottom left hand corner.
3、Now tap on Open In….
4、In the popup menu, tap on Pages, Numbers, or Keynote. For instance, if you’re trying to open a spreadsheet, you’d have the option to open it in Numbers. If you’re open a word document, Pages should be an option.
If you have multiple files you need to move over to iCloud from Dropbox, you can do so quickly from a Mac by copying and pasting the files into iCloud.
