It’s been a while since Microsoft rolled out the docx format which handles documents in the new releases of Microsoft Office, this format has been the default format for all Office documents since Microsoft Office 2007 was released, however there are a handful of users who still prefer and stick to previous versions of Microsoft Office, this may lead to incompatibility if you receive or create a document in a newer version of Microsoft Office.
You could fix this incompatibility issue simply by upgrading to a newer version of Microsoft Office, however if you don’t find it worth the investment you could try one of the tools below to convert your docx file to the traditional doc format or use a free, simpler docx viewer.
This is a very convenient way to access your docx files, as the domain name suggests, docx-converter.com lets you instantly convert your files to a doc format in exchange of your email address, well if you are paranoid about the Internet and privacy in general you probably won’t like the idea of giving away your email address (which they claim is used to notify completion of conversion), in that case you could try any of the other services listed below.
This is another online free conversion tool, however is not as specific, apart from converting your open XML files to traditional office files it also allows conversion of dozens of other file formats, this service requires your email address too, to allow you to receive the converted files.
This is a desktop application for Windows operating systems, completely portable, and an efficient alternative to downloading the latest version of Microsoft Office, it is only 4MB in size and supports a range of document types.
The open source alternative to Microsoft Office, this suite supports the latest open xml office formats as well and works on Windows, Mac and Linux.
There are plenty of other ways to gain access to the latest open XML formats however making a switch towards one of the newer versions anytime soon is inevitable., personally I’d recommend you switch to Open Office, as it features most of the features that Microsoft Office does and not to forget, it’s totally free!
