If you’re looking for Microsoft-caliber applications for free, OpenOffice has alternatives to Word, PowerPoint, Excel, Access, and more. OpenOffice has come a long way after racing to improve its compatibility with Microsoft Office.
Free: The most significant feature of OpenOffice is that it’s free — no subscription fee, no lump sum, no upsell to a pro version. If your business needs don’t include complex word-processing or database-management features, then OpenOffice is a bargain.
Compatibility: OpenOffice supports the same file formats as rival programs like Word and Excel. Those coming from Microsoft will be pleased to hear that Office files work in OpenOffice, too.
Function: For most basic uses, OpenOffice holds its own. Math allows you to create basic charts and cell-dependent calculations just like Excel, and most useful features from Microsoft Word also appear in Writer, including spell checkers and most text-formatting options.
