Settings.set method

Sets or creates the specified setting.

Hosts: Access, Excel, PowerPoint, Word
Available in Requirement set Settings
Last changed in 1.1
Office.context.document.settings.set(name, value);


    Type: string

    The case-sensitive name of the setting to set or create.

    Type: string, number, boolean, null, object or array

    Specifies the value to be stored.


The set method creates a new setting of the specified name if it does not already exist, or sets an existing setting of the specified name in the in-memory copy of the settings property bag. After you call the Settings.saveAsync method, the value is stored in the document as the serialized JSON representation of its data type. A maximum of 2MB is available for the settings of each add-in.

Important: Be aware that the Settings.set method affects only the in-memory copy of the settings property bag. To make sure that additions or changes to settings will be available to your add-in the next time the document is opened, at some point after calling the Settings.set method and before the add-in is closed, you must call the Settings.saveAsync method to persist settings in the document.


function setMySetting() {
    Office.context.document.settings.set('mySetting', 'mySetting value');
