11. A method comprising:

accessing spreadsheet data of a spreadsheet having one or more data validation rules;

causing display of a synchronization interface to present a status of synchronization of the spreadsheet data with respect to a plurality of applications hosted by one or more application servers;

determining, by one or more processors, whether the one or more data validation rules include the set of constraints;

in response to determining the one or more data validation rules exclude at least one constraint from the set of constraints, causing display, within the synchronization interface, of a notification that includes an indication that the application data is unable to be synchronized with the spreadsheet data, the notification specifying, one or more additional validation rules to associate with the spreadsheet to trigger synchronization of the application data with the spreadsheet data, the one or more additional validation rules corresponding to the at least one constraint that has been determined to be excluded from the one or more data validation rules;
