load(options)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(options?: Excel.Interfaces.ChartCollectionLoadOptions & Excel.Interfaces.CollectionLoadOptions): Excel.ChartCollection;Parameters
Provides options for which properties of the object to load.
Returns
load(propertyNames)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames?: string | string[]): Excel.ChartCollection;Parameters
- propertyNames
-
string | string[]
A comma-delimited string or an array of strings that specify the properties to load.
Returns
Examples
await Excel.run(async (context) => {
const charts = context.workbook.worksheets.getItem("Sheet1").charts;
charts.load('items');
await context.sync();
for (let i = 0; i < charts.items.length; i++) {
console.log(charts.items[i].name);

load(propertyNamesAndPaths)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths?: OfficeExtension.LoadOption): Excel.ChartCollection;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.ChartCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
toJSON(): Excel.Interfaces.ChartCollectionData;Returns
