. (JSON.stringify
, in turn, calls the toJSON
method of the object that's passed to it.) Whereas the original Excel.WorksheetCustomPropertyCollection
object is an API object, the toJSON
method returns a plain JavaScript object (typed as Excel.Interfaces.WorksheetCustomPropertyCollectionData
) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
toJSON(): Excel.Interfaces.WorksheetCustomPropertyCollectionData;
