Google Docs offers online creation and editing of documents such as presentations, text files and spreadsheets. You can upload a variety of document types into the Web-based suite of editing tools. Google Docs can also convert Microsoft Office documents into its own format. For example, if you'd like to edit a PowerPoint presentation without using Microsoft PowerPoint, you can upload the PowerPoint and convert it into Google Doc's presentation format.
Navigate your browser to Google Doc's homepage (see Resources). Sign into your Google account. Enter your Google credentials into the "Email" and "Password" fields on the page, and then click the "Sign-in" button.
Click the "Upload" button, once you've signed into Google Docs. Select the "Files" option from the "Upload" menu. Locate your PowerPoint presentation on your computer, using the file explorer window that appears. Click "OK" after locating your file. The "Upload Settings" menu will appear.
Check the box labeled "Convert documents, presentations, spreadsheets, and drawings to the corresponding Google Docs format" in the "Upload Settings" menu. Click "Start upload" to begin importing your PowerPoint presentation into Google Docs. The file will be automatically converted during the upload process.
