US Patent 10977211 Effective deployment of spreadsheets in browser environments

A file management system may include a file server that performs calculations of a spreadsheet file instance to generate a dataset that includes values in the spreadsheet file instance. The file management system also may include an application operating at a client device that is in communication with the file server via a network. The application may receive, via the network, a version of the dataset comprising the values generated by the calculations performed by the server. The application may visualize a spreadsheet at the user interface. The visualized spreadsheet may display at least a subset of the values. In one case, protected contents of one or more cells in the spreadsheet may be converted to other values when displayed at the user interface.
