Abstract: Embodiments of the present disclosure provides methods and spreadsheet managing systems for presenting designated spreadsheet sections of a spreadsheet through a web interface without exposing other spreadsheet sections across a network service. The methods and systems provide a secure layer-based presentation of spreadsheet sections for visualization and manipulation of data in designated spreadsheet sections to derive output from calculations based on data from other spreadsheet sections without exposing or altering other spreadsheet sections. A first user can share a resource locator with second user(s) along with one or more permissions for accessing the designated spreadsheet sections. The second user(s) can manipulate the designated spreadsheet sections to get an output based on the data and calculations in the designated spreadsheet sections.
