load(propertyNamesAndPaths?: OfficeExtension.LoadOption): Excel.QueryCollection;
Parameters
- propertyNamesAndPaths
- OfficeExtension.LoadOption
propertyNamesAndPaths.select
is a comma-delimited string that specifies the properties to load, and propertyNamesAndPaths.expand
is a comma-delimited string that specifies the navigation properties to load.
Returns
toJSON()
Overrides the JavaScript toJSON()
method in order to provide more useful output when an API object is passed to JSON.stringify()
. (JSON.stringify
, in turn, calls the toJSON
method of the object that is passed to it.) Whereas the original Excel.QueryCollection
object is an API object, the toJSON
method returns a plain JavaScript object (typed as Excel.Interfaces.QueryCollectionData
) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
toJSON(): Excel.Interfaces.QueryCollectionData;
Returns
Office Add-ins
