Class Properties

AI-generated Key Takeaways

• The properties object allows access to user, document, or script properties through methods of the PropertiesService.

• Properties cannot be shared between different scripts.

• The Properties object includes methods for deleting properties, retrieving keys or all properties, and setting individual or multiple properties.

Properties

The properties object acts as the interface to access user, document, or script properties. The specific property type depends on which of the three methods of PropertiesService the script called: PropertiesService.getDocumentProperties(), PropertiesService.getUserProperties(), or PropertiesService.getScriptProperties(). Properties cannot be shared between scripts. For more information about property types, see the guide to the Properties service.

Detailed documentation

deleteAllProperties()

Deletes all properties in the current Properties store.

// Deletes all user properties.
const userProperties = PropertiesService.getUserProperties();
userProperties.deleteAllProperties();

Return

Properties — this Properties store, for chaining

---

deleteProperty(key)

Deletes the property with the given key in the current Properties store.

// Deletes the user property 'nickname'.
const userProperties = PropertiesService.getUserProperties();
userProperties.deleteProperty('nickname');

Parameters

Name	Type	Description
key	String	the key for the property to delete

Return

Properties — this Properties store, for chaining

---

getKeys()

Gets all keys in the current Properties store.

// Sets several properties, then logs the value of each key.
const scriptProperties = PropertiesService.getScriptProperties();
scriptProperties.setProperties({
  cow: 'moo',
  sheep: 'baa',
  chicken: 'cluck',
});
const keys = scriptProperties.getKeys();
Logger.log('Animals known:');
for (let i = 0; i < keys.length; i++) {
  Logger.log(keys[i]);
}

Return

String[] — an array of all keys in the current Properties store

---

getProperties()

Gets a copy of all key-value pairs in the current Properties store. Note that the returned object is not a live view of the store. Consequently, changing the properties on the returned object will not automatically update them in storage, or vice versa.

// Sets several script properties, then retrieves them and logs them.
const scriptProperties = PropertiesService.getScriptProperties();
scriptProperties.setProperties({
  cow: 'moo',
  sheep: 'baa',
  chicken: 'cluck',
});

const animalSounds = scriptProperties.getProperties();

// Logs:
// A chicken goes cluck!
// A cow goes moo!
// A sheep goes baa!
for (const kind in animalSounds) {
  Logger.log('A %s goes %s!', kind, animalSounds[kind]);
}

Return

Object — a copy of all key-value pairs in the current Properties store

---

getProperty(key)

Gets the value associated with the given key in the current Properties store, or null if no such key exists.

// Gets the user property 'nickname'.
const userProperties = PropertiesService.getUserProperties();
const nickname = userProperties.getProperty('nickname');
Logger.log(nickname);

Parameters

Name	Type	Description
key	String	the key for the property value to retrieve

Return

String — the value associated with the given key in the current Properties store

---

setProperties(properties)

Sets all key-value pairs from the given object in the current Properties store.

// Sets multiple user properties at once.
const userProperties = PropertiesService.getUserProperties();
const newProperties = {

  language: 'EN'
};
userProperties.setProperties(newProperties);

Parameters

Name	Type	Description
properties	Object	an object containing key-values pairs to set

Return

setProperties(properties, deleteAllOthers)

Sets all key-value pairs from the given object in the current Properties store, optionally deleting all other properties in the store.

// Sets multiple user properties at once while deleting all other user
// properties.
const userProperties = PropertiesService.getUserProperties();
const newProperties = {
  nickname: 'Bob',
  region: 'US',
  language: 'EN'
};
userProperties.setProperties(newProperties, true);
