I have been using spreadsheets on daily basis, they are a great way either to gather data or manipulate it.
They are great, however, I usually encounter performance issues. Such as, when many people connect to the same sheet with me, it becomes slow and it causes productivity loss. And my biggest problem was how to synchronize and update specific cells of data between two sheets or more, and let data flow between them.
Here where the idea of OceanSheet came up, which is basically a tool that automates this by creation a reliable connection between all my sheets and update data between them automatically.
