LibreOffice

r you here, the free open-source alternative that is thought to be the new OpenOffice. LibreOffice includes a spreadsheet creator, text edition tool, presentation creator, graphic editor, formula creator, and a database creation tool. In short, it offers (for free) exactly what Microsoft Office offers for a lot of money. These features are like a free Microsoft Word, Excel, Access, PowerPoint and the rest of the components of the Office suite. Plus, the files created using Microsoft Office can be open and edited using LibreOffice and vice versa. If you don't want to waste money but you want to enjoy all the power of a good office suite, LibreOffice is what you need.
