Embodiments are disclosed for managing co-editing management. A method of co-editing management includes detecting a modification operation to be performed on a sequential data structure being edited by one or more client devices, determining a segment of the sequential data structure associated with the modification operation based on a logical index associated with the modification operation, generating a tree structure associated with the segment, a root node of the tree structure corresponding to the modification operation, determining a global index for the root node of the tree structure, and sending an update corresponding to the modification operation, including the root node and the global index, to a co-editing server to be distributed to the one or more client devices.
