Systems and methods are disclosed herein for editing a collaborative spreadsheets hosted on a server. Multiple users may edit the spreadsheet, resulting in situations of intersecting or conflicting edits. A change provided by one user may intersect the cells affected by a change provided by another user. In these cases, one user's change is transformed against the other user's change. In this manner, the conflict is resolved and both changes can be applied to the spreadsheet. Each user device may perform these transforms, and the server may also perform these transforms. This can result in transmission of a reduced volume of data over a network between the devices and the server, in comparison with other methods.
