If you're like me, you probably think that Google Docs are the greatest things since sliced bread. That is, unless you need to use the document in a way that doesn't involve the web, say like if you want to upload the document into another program that isn't setup to accept Google based files.
If you need to convert your Google document into another format, the process is simple. With your document open, click on File, and then on Download as, which is about two-thirds of the way down the page. This will open up a list of seven different formats you can choose from, such as .docx, .pdf, .epub.
When you click on your option of file type, it will save it in your downloads folder. From there, you can upload it to that pesky program that hasn't quite gotten the hang of playing nice with Google.
