Purchasing microsoft office is a bit expensive. If we need office for basic stuff like simple presentations and document editing, we can go for
a free alternative. There are several free and open source office suites available. I used many of them but these three are user friendly
and have good product support.
1. Apache Open Office
Apache OpenOffice is the leading open-source office software suite for word processing, spreadsheets,presentations, graphics, databases and more. It is available in many languages and works on all common computers. It stores all your data in an international open standard format and can also read and write files from other common office software packages. It can be downloaded and used completely free of charge for any purpose.
2. Libre Office
The LibreOffice software is developed by users, just like you, who believe in the principles of free software and in sharing their work with the world in a non-restrictive way. At the core of these principles is the promise of better-quality, highly-reliable and secure software that gives you greater flexibility at zero cost. Beyond this, the driving factor behind the community is personal choice and transparency, which translates practically into wider compatibility, more utility and no end-user lock-in to using just one product.
3. Kingsoft Office Suite Free
Kingsoft Office Suite Free 2012 is perhaps the most versatile free office suite, which includes free word processor, spreadsheet program and presentation maker. These three programs help you deal with office tasks with ease:
Writer – Efficient word processor;
Presentation – Multimedia presentations creator;
Spreadsheets – Powerful tool for data processing and data analysis
Although it is a free suite, Kingsoft Office comes with many innovative features, including a paragraph adjustment tool, and multiple tabbed feature. It also hasOffice to PDF converter, automatic spell checking and word count features. In this latest version, new features such as watermark in document, andconverting PowerPoint to Word documents are also supported.
