Remarks
valueAsJson
A JSON representation of the values in this named item. Unlike NamedItem.value, NamedItem.valueAsJson supports all data types which can be in a cell. Examples include formatted number values and web images, in addition to the standard boolean, number, and string values. Data returned from this API always aligns with the en-US locale. To retrieve data in the user's display locale, use NamedItem.valueAsJsonLocal.
readonly valueAsJson: CellValue | string;Property Value
Excel.CellValue | string
Remarks
valueAsJsonLocal
A JSON representation of the values in this named item. Unlike NamedItem.value, NamedItem.valueAsJsonLocal supports all data types which can be in a cell. Examples include formatted number values and web images, in addition to the standard boolean, number, and string values. Data returned from this API always aligns with the user's display locale. To retrieve data independent of locale, use NamedItem.valueAsJson.

Excel.CellValue | string
Remarks
visible
Specifies if the object is visible.
visible: boolean;Property Value
boolean

const totalName = sheet.names.getItemOrNullObject("TotalAmount");
totalName.load();
await context.sync();
if (totalName.value) {
totalName.delete();
// Replace the named item (TotalAmount) with the actual formula for TotalAmount to avoid displaying #NAME in the cell.

range.load('address');
await context.sync();
console.log(range.address);
});
getRangeOrNullObject()

getRangeOrNullObject(): Excel.Range;Returns
Remarks
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.NamedItemLoadOptions): Excel.NamedItem;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.NamedItem;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 names = context.workbook.names;
const namedItem = names.getItem('MyRange');
namedItem.load('type');
await context.sync();
console.log(namedItem.type);
});
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?: {
select?: string;
expand?: string;
}): Excel.NamedItem;Parameters
- propertyNamesAndPaths
-
{ select?: string; expand?: string; }
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
set(properties, options)
Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.
set(properties: Interfaces.NamedItemUpdateData, options?: OfficeExtension.UpdateOptions): void;Parameters
- properties
- Excel.Interfaces.NamedItemUpdateData
A JavaScript object with properties that are structured isomorphically to the properties of the object on which the method is called.
- options
- OfficeExtension.UpdateOptions
Provides an option to suppress errors if the properties object tries to set any read-only properties.
Returns
void
set(properties)
Sets multiple properties on the object at the same time, based on an existing loaded object.
set(properties: Excel.NamedItem): void;Parameters
- properties
- Excel.NamedItem
Returns
void
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.NamedItem object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.NamedItemData) that contains shallow copies of any loaded child properties from the original object.
toJSON(): Excel.Interfaces.NamedItemData;Returns
