US Patent 9875226 Performing server-side and client-side operations on spreadsheets

A method for obtaining server-side and client-side calculations performed on a spreadsheet includes loading, on a client computer, a spreadsheet stored on a server and receiving an input from a user on the client computer, where the input causes a calculation of one or more cell values in the spreadsheet. The client computer performs the calculation of the one or more cell values on the client computer and sends the input to the server to perform the calculation of the one or more cell values on the server. The client computer then displays in the spreadsheet a result of the calculation of the one or more cell values to the user, where the result of the calculation is taken from the quicker of the calculation performed on the client computer or the calculation performed on the server.
