While Google has a couple of Office document solutions in place, all of them rely on connectivity, for instance Google Docs for Android which was recently enhanced and renamed to Google Drive. However, there's no stand-alone Office documents solution available and that part took over a lot of 3rd party applications. One of them, Quickoffice, which is preinstalled on a many Android devices, was now acquired by Google. As Google said, today's consumers, businesses and schools use Google Apps to get stuff done from anywhere, with anyone and on any device. However, Quickoffice has a strong base of users and Google looks forward to support them while it's now working on an even more seamless, intuitive and integrated experience.
Quickoffice has indeed an established track record of enabling seamless interoperability with popular file formats. It allows to create, edit and share Microsoft Office files on Android devices, incl. Word documents, Excel spreadsheets and PowerPoint presentations, as well as annotate Acrobat PDF files.
While Google is "excited to welcome the Quickoffice team and their users to Google", neither Google nor Quickoffice has disclosed any further information.
