It is very easy to use! The interface is simple and intuitive. I love how you can easily share your sheet with others in real time. Sometimes it's not possible to add new rows or columns but that happens rarely. There are many features that we haven't used yet so there might be more useful ones out there. Try using this tool if you need an effective way of sharing information between colleagues quickly. We have solved problems related to sending files from one person to another within our team without having to send emails.
