For a while, nonprofit organizations' choice of office suites was limited to Microsoft Office or... Microsoft Office. But over time, a viable open source option has emerged: OpenOffice.org. Should you consider OpenOffice? Will it make sense for your users and organization? In this article, updated in July 2010, we compare Microsoft Office 2010 to OpenOffice.org 3.2.
Once upon a time, nonprofits that wanted a powerful, useful-friendly word processing, spreadsheet, and presentation package were faced with limited options: Microsoft Office or... Microsoft Office. But over time, an open-source alternative, OpenOffice.org, has become increasingly popular, making it a viable, affordable option for organizations seeking a productivity suite.
Before we examine the specific features of Microsoft Office and OpenOffice, it may be helpful to step back to compare the philosophical differences between the two packages, and how these differences might impact how you purchase and use them.
With commercially licensed software like Microsoft Office, a product is developed by a single company; sales help fund product testing and development, marketing and sales, as well as salaries and shareholder dividends. In contrast, open-source software like OpenOffice is developed collaboratively, often by volunteers, and freely distributed, allowing anyone to use, redistribute, adapt, or improve the code — all free of charge.
The open-source philosophy is not just limited to software, and can attract loyal adherents who believe that information should be shared freely. Likewise, some consumers feel more comfortable with a for-profit model they feel rewards ingenuity and innovation. If you have deep convictions in either direction, we suspect that we're not going to change your mind here. However, each model does offer tangible advantages:
Microsoft Office is nearly ubiquitous in office settings these days, making its interface the de-facto standard for how office suites operate. However, Office 2007’s new “ribbon” interface is different enough from the Office 2003’s interface that the average user may require additional training and support when making the transition. Even Microsoft Office “super-users” may find the upgrade frustrating, as features they learned inside out have moved.
Office 2010 keeps with the ribbon interface, with only slight modifications. It has also implemented several important interface improvements, such as adding the File menu back into the tool bar, which makes it easier to find the controls to open and save documents. The pretty, modern interface lends additional polish to the suite.
OpenOffice 3’s interface, in contrast, is very similar to Office 2003, making it an intriguing option for those who are concerned about a wholesale move to the ribbon interface. Anyone who has used Word or Excel 2003 will feel comfortable in Write and Calc. A move from Microsoft Office 2003 to OpenOffice 3 might be compared to a move from Office 2000 to Office 2003: there are small differences, and users who have learned things by rote may require some training, but the concepts are all the same. In fact, many regard OpenOffice 3 as simpler, and thus easier to learn, than Microsoft Office 2010. OpenOffice 3 is also about as polished as Office 2003 — perfectly functional, but not as sleek as Office 2010.
Some of the more advanced features differ more between any version of OpenOffice and Microsoft Office. For instance, the available templates are substantially different between the two suites, so those accustomed to using pre-packaged layouts for documents or charts may need to make some adjustments.
For most computers that you would actually want to use, both OpenOffice 3 and Microsoft Windows 2010 will work fine. While OpenOffice is said to run a bit slower, particularly when opening up complex documents in Microsoft's proprietary formats, the difference is negligible if you've purchased your computer in the last couple of years. Both platforms also offer comparable support for Macs.
OpenOffice 3 offers better support for older computers than the latest version of Microsoft Office. For instance, Office 2010 notes its minimum spec is a Pentium 700MHz with 512 MB of RAM, while OpenOffice lists 256 MB of RAM (although 512 MB RAM is recommended). While Office 2010 requires Windows 7, XP, or Vista to run fully, OpenOffice will run on Windows 2000 or 2003. What's more, OpenOffice will run under Linux, and Linux runs much more effectively on old computers than Windows 7 or XP. This makes Linux and OpenOffice a practical combination even on older computers, especially those that require few other applications (as you might find in a public computer lab setting.)
There's more support for Microsoft Office than anyone could possibly take advantage of: Official support from Microsoft itself, authorized support from people who have earned Microsoft licenses, professional call centers, dozens of books, and countless websites offering tips and guides for modifying, configuring, and using Office software. OpenOffice's support is more community driven, and generally free, with a documentation project and discussion forums led by volunteers. It's easier to find Microsoft Office training and support, and there are some free resources  specifically for nonprofits, but tailored support is likely to cost more.
One final consideration: because OpenOffice has much looser licensing requirements, you needn’t worry about installing unlimited copies around your office or for friends or partner organizations. When you buy or receive a version of Office 2010, however, you may only install it on a specified number of computers within your organization, so you'll need to keep track of exactly where it's been installed.
In general, both Office 2010 and OpenOffice can create files that can be read by others, with some caveats. In the case of Office 2010, this is because Microsoft has established de facto file standards such as .doc (and .docx) for Word documents and .xls (and .xlsx) for Excel. Partners that are running Office 2003 or older versions may need to convert the files Office 2010 creates from the new file formats (docx) to the older ones (like .doc) to be able to open them. This isn’t done automatically in the older versions, although Microsoft offers a free utility to do it for you.
OpenOffice, on the other hand, uses open standards for its native files, but can both read and write files in Microsoft's format. In fact, OpenOffice users can choose to automatically save out files in Microsoft 2003 formats by default. OpenOffice has invested a lot of effort in ensuring that Writer, Calc, and Impress users can share documents with Microsoft users and has succeeded in all but a few specific cases … as long as you’re trying to share documents in Office 2003 or prior. OpenOffice can open and save Office 2003 documents with a high degree of fidelity, with only a few exceptions. If you’ve created Word documents that make extensive use of columns, header formats, and embedded images, the file is likely to show up in Writer with minor formatting issues that have to be adjusted by hand. This isn’t likely to be prohibitive for a document or two, but could be a time consuming for a whole library of templates and collateral.
The two applications are also incompatible when it comes to macros or spreadsheet pivot tables. Both applications support both features (pivot tables are created with a feature called Data Pilot in OpenOffice), but you will not be able to use the macros or pivot tables created in one application with the other. You may also have some minor issues with translating charts from one spreadsheet program to the other.
Interestingly, OpenOffice can open substantially older versions of Microsoft Office files than Microsoft Office itself can, or even some corrupted files that Microsoft Office can’t open. For an IT department, OpenOffice is worth having around just for that.
However, OpenOffice does not have complete support for the new file formats created by Office 2007 and 2010. In our tests, simply saving an Office 2003 document into the Office 2010 file format and then opening that same document in OpenOffice resulted in a substantial loss of formatting fidelity, particularly from Word to Writer. As these file formats are fairly new, one would expect the OpenOffice community to improve their support over time. OpenOffice also cannot save to the new 2007 and 2010 file formats; however, as Office 2010 is able to open the Office 2003 file formats, this is not a substantial limitation.
Both applications now provide the ability to export any file to an un-editable PDF format – ensuring that viewers can see the document exactly as you intended.
Microsoft Office 2010 also introduces new web-collaboration features. You can save any Office document to Microsoft’s “SkyDrive” — the company’s online server — and access it via Microsoft’s new Web Apps, which provides online stripped-down versions of the office applications. Here, you can view the complex formatting of your offline versions, although not necessarily edit it. For instance, Web Apps will allow you to apply heading styles that you’ve created in a desktop version of Word, but not to edit those styles or create new ones.
Microsoft is also moving (slowly) toward supporting real-time online collaboration. Currently, multiple users can edit documents simultaneously in the Web Apps version of Excel but not Word or PowerPoint. However, this is likely to change over time. Interestingly, Microsoft has just announced a version of Web Apps called Web Docs that integrates with Facebook. Presumably, this will allow easy document collaboration among Facebook contacts.
OpenOffice doesn’t offer any of these features, continuing to operate on a pure desktop model. You can certainly email files to yourself or others, but you can’t edit them directly on the web, or collaborate with others in real time.
Microsoft Office and OpenOffice are both reasonably secure as long as you follow standard security procedures: install updates and patches as soon as they're released; maintain firewalls, antivirus, and antispyware; and so on. However, while OpenOffice let everyone know about possible security issues (allowing users to protect themselves and hackers to potentially exploit issues), Microsoft keeps security issues close to the vest — possibly preventing hackers from finding out about them, but also forestalling users' ability to take protective measures beyond the standard security updates Microsoft provides automatically. It's like the dilemma that arises each time police officers are faced with a serial killer: Should they alert people and possibly make the perp move on to another community, or should they keep their investigation quiet and zero in on the guy? There are strong arguments for both approaches.
For many folks, one of the big advantages of Microsoft Office is its integration with Microsoft Outlook, an email and calendaring software package (among other things). These features not only allow you to send a document directly from the Microsoft Office (for instance, you can send a Word document in an email directly from the Word interface), but to preview Microsoft Office documents directly in Outlook without opening the application.
So let's get on with it, you may be saying. I want a head-to-head comparison of the feature differences between the two suites. This is very difficult, primarily as the applications are so fundamentally similar. Each suite has been copying the best enhancements and innovations of the others for years, so you need to be doing pretty complex things before you find either suite lacking.
In general, Microsoft Office has a greater depth when it comes to very advanced features. For instance:
On the other hand, OpenOffice tends to be somewhat simpler to understand, and can output to some more useful file formats. For instance:
What do we recommend? If you still haven’t made up your mind, we’ll leave you with a few specific scenarios for when one package might work better than another:
Both Microsoft Office and OpenOffice are strong platforms that will support office productivity. You might want to consider installing both office suites to allow your users a choice. Personally, we like having choices. If you've read this far, the same may apply to you.
