Softmaker FreeOffice is the free version and a very nice alternative to the Microsoft Office suite. Here we will install FreeOffice on Ubuntu 20.04 LTS Linux using its official repository.
FreeOffice doesn't offer all applications as we have in MS-office, instead, it focuses on three main day to day usage office apps. They are Text (an alternative to MS Word), Presentation (like PowerPoint), and PlanMaker (SpreadSheet).
With the help of this free office suite, we cannot only open native file formats of Microsoft office such as DOCX, XLSX, and PPTX, even saving of files into them is possible as well.
Those who are already familiar with the interface of Microsoft office would not feel a problem in getting used to FreeOffice because of its MS-office like ribbon menu panel. However, a classic one is also available if some of us would like to use that.
