One thing that many people are concerned with when they move from Microsoft Window to a Linux based operating system is that they will not have the office software that they are used to working with. While the software that is available for a Linux based operating system may be a little different than what you are used to with Windows, there are still options and programs that can help anyone.
Open Office is currently the most widespread and well known of the programs that are considered office software. It has been made to be compatible with many, if not all, major office programs out there. In fact, many people who do not use Linux also use openoffice, because of the complete compatibility that it has. It is a completely free program, and has multiple applications that can be used.
If you are looking for something that focuses just on spreadsheets, Gnumeric could be a great option. The entire goal of the program has been to make the absolute best spreadsheet possible. They have also made it an effort to not copy other, existing applications exactly. Gnumeric is able to open files that have been saved on other spreadsheets.
If you are looking for a processor that will help you structure your documents how you want them to be, and give a great looking product right away, you may want to look at LyX. This program focuses on the structure of the document more than the appearance, and you don’t have to worry nearly as much about formatting or playing around to make it look good.
No matter what you are looking for in your office software, you can find great options that are free and open source. If you still prefer Microsoft Office, a program such as Wine may be able to help you get what you want for your Linux based operating system.
