Being unable to view a document because you don’t have the latest software is a thing of the past with ZamZar. ZamZar is a free online document conversion tool that allows you to upload a document(s) and have it converted into a format you can open.
They have an exhausted list of conversion types that you can view here. I recently had a chance to try this out when a client who sent me a docx file from Microsoft 2007. The process is simple upload the file, pick which type you want to receive back and hit submit. A couple minutes later my Office 2003 compatible file arrived safe and sound to my e-mail box.
