Apache had actually developed Open Office for over twenty years before they felt that the program was able to rival (and bettered, in many instances) what was on the market. Open Office can be downloaded for free, but despite this, a lot of thought and effort has gone into its development. Standard formats are used in Open Office for creating and saving your data, which means that all files created on Open Office can be run on programs such as Microsoft Word, Apple Pages and Microsoft Excel. Not only does Open Office support a large number of file formats for all of its programs, but it also runs in many different languages and can be installed on most Operating Systems, including Mac and Windows.
Apache Open Office is a widely used and free Office Suite that comes loaded with a range of programs, from a spreadsheet creator and word processor to a slideshow maker and a spreadsheet.
