The internet is ablaze with “cloud computing” solutions, ranging from options for tracking social media to synchronizing company calendars to using online software and more. One of the most powerful tools, however, is that provided by Google Docs and other cloud-based file editing programs. These are especially valuable if you’re going to collaborate on a major excel project.

The concept is easy enough to learn. You just visit the Google Docs website and sign up for their service by entering your preferred email and password. Those who already have Google services, such as Gmail or Google Calendar, will be able to use their existing username and password.

Once within the GDocs interface, you will be able to create new documents of various types, including spreadsheets. Formatting, titling, and otherwise editing these is instinctive, but sharing the document can be a little more tricky.

At the top of your document, a small lock accompanied by the word “private” should be visible, indicating that only you are able to view and edit that file. Clicking here will allow you to share it with either a group of viewers, a selection of editors, or even the general public.

Once shared, other great collaboration features kick in. You will be able to see other edits in real time, ensuring no crossed wires. You will also be able to see who is viewing the document as you work, and you can use a built-in chat feature to communicate about the work that you’re doing.

Google Docs is an especially valuable tool because it’s free to use, ensuring that you can work with anyone who has internet access. While other online editing options are available, including some official Microsoft Word options, these will not be available to those who haven’t paid for them.
