We apologize for any inconvenience this may cause, but a more secure, stable, and performant Community experience is coming soon!
The new Appian Community launches August 3, followed by Appian Academy on August 7. During the migration, Appian Community Edition, Appian Academy, Documentation, Certifications, Instructor-led Customer Training, Partner Sales Training & Accreditation, and Forum (for Appian Partners and Customers only) will remain available.

Hi, you can use the map function for this. We don't have any direct way of doing that we have to apply loop to create a custom map and then use it.
https://docs.appian.com/suite/help/22.3/fnc_system_map.html
a!localVariables( local!xyz:{ a!map(id: 1, name: "Jane Doe"), a!map(id: 2, name: "John Doe") }, a!forEach( items: local!xyz, expression: a!map( id:fv!item.id, name:fv!item.name, newKey1:null() ) ) )
You can use a!update(). It is used to update the value of the passed key and if the key doesn't exist, then it will create a new one.
