Google has broadened the number of online applications that people can use offline, adding spreadsheets and presentations to the mix.
However, unlike with word-processing documents, spreadsheets and presentations can only be viewed, not edited, according to a post by marketing manager Andrew Chang on the Google Docs blog Friday. That's still useful, though. Chang gives the example of giving a slide presentation without having to worry about network access.
The offline access uses the Google Gears technology the search engine giant introduced in 2007 as an open-source project.
Google is trying to take on Microsoft with its online software, butthan Google does to Microsoft with online office suites.
