If you like to open .docx files without Office Word 2007, there’s a new Firefox extension from Microsoft that should help. Available for Windows as well as Linux machines.
Open DOCX files as an HTML document in any web browser
Called OpenXML viewer, this plug-in (download link) lets you read docx files inside the Firefox browser just like any other HTML web page while retaining all the text formatting and layout.
There’s a command-line version of OpenXML viewer (download link) available as well for converting docx documents into HTML files that you may then open in any other web browser.
Other alternatives for reading docx files without Microsoft Office 2007 include Internet Explorer, Gmail, Email, Word viewer and the converter for Mac.

Great one. but if the document contains embedded objects then it will not work. i mean you cannot open the embedded file. Right Amit?

Brilliant to have these updates supplied .. just as you need them – had endless probs opening attachments sent to me, docx was one and the other were the xls and xlsx which, having upgaded to OpenOffice 3, it opened all and anything from any source in one click! i also use Opera 9 where some programs and toolbars don’t work with it (yet).
Tks, Severin

Microsoft has Word Viewer 2003/2007 and which can be freely downloaded from Microsoft and then edited in the version of Microsoft word version (even Office 2000) available with you.

a simpler alternative would be renaming .docx to .zip and extracting it. it works flawless

Dear Amit,
I read your article about opening Office 2007 files in Firefox.
I did as mentioned by you in your post but I was not able to see the file in a formatted fashion.
I am new to XML and dont know how to tackle it.
I have a DOCX file and I want to read it without Office 2007.
How do I open document.xml so that it does not not look like HTML source code?
Regards,
Ips
