US Patent 9959098 Data processing systems and methods

A system and methods for dynamically creating spreadsheet workbooks at runtime on a computing device from a set of pre-defined spreadsheet modules. Each spreadsheet module has an associated interface definition, allowing users more easily to combine multiple modules into more complex spreadsheet applications. Interfaces are defined using a Spreadsheet Interface Definition Language (SIDL) which enables spreadsheet models to be defined independent of their implementation. Modules can be either pre-constructed as spreadsheet workbooks, or dynamically created at run time from module definitions.
