A method and system for providing modular application for use within a cloud-based file includes storing on a cloud computing service a link to a modular application configured to be used with a cloud-based file, receiving a request to access the link to the modular application, determining whether the request source is associated with the cloud computing service, and providing an option to access the requested modular application. The option can be for a trial of the modular application or to create a cloud-based file using the modular application.
