Box Lets Users Create Microsoft Office Documents in the Cloud

Box Inc. will let users create new Microsoft Corp. Office documents and spreadsheets from within the cloud-storage vendor’s own programs as it attempts to add business customers.

The new features are the first fruits of a partnership announced in February in which Box became an online-storage partner for Microsoft’s Office, said Box Chief Executive Officer Aaron Levie. Customers already have more than a billion Office documents stored in Box, he said. Shared customers include Toyota Motor Corp. and General Electric Co., Box said in a statement Tuesday.
