Excel.Runtime class

Package:

excel

Represents the Excel Runtime class.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: ExcelApi 1.5 ]

Properties

context	The request context associated with the object. This connects the add-in's process to the Office host application's process.
enableEvents	Toggle JavaScript events in the current task pane or content add-in.

Methods

load(options)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
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)	Sets multiple properties on the object at the same time, based on an existing loaded object.
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.Runtime object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.RuntimeData) that contains shallow copies of any loaded child properties from the original object.

await Excel.run(async (context) => {
    context.runtime.load("enableEvents");
    await context.sync();

    // check if events are enabled and toggle accordingly
    const eventBoolean = !context.runtime.enableEvents
    context.runtime.enableEvents = eventBoolean;
    if (eventBoolean) {
        console.log("Events are currently on.");

        console.log("Events are currently off.");
    }

    await context.sync();
});

Method Details

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.RuntimeLoadOptions): Excel.Runtime;

Parameters

options

Excel.Interfaces.RuntimeLoadOptions

Provides options for which properties of the object to load.

Returns

Excel.Runtime

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.Runtime;

Parameters

propertyNames

string | string[]

A comma-delimited string or an array of strings that specify the properties to load.

Returns

Excel.Runtime

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.Runtime;

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

Excel.Runtime

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.RuntimeUpdateData, options?: OfficeExtension.UpdateOptions): void;

Parameters

properties

Excel.Interfaces.RuntimeUpdateData

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.Runtime): void;

Parameters

properties

Excel.Runtime

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.Runtime object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.RuntimeData) that contains shallow copies of any loaded child properties from the original object.

toJSON(): Excel.Interfaces.RuntimeData;

Returns

Excel.Interfaces.RuntimeData
