Transforming content in a document using chained applications in a client-server architecture

A method for displaying content in a graphical user interface (GUI) of an instance of a frontend application providing frontend functionality associated with a cloud platform. The method includes initiating a first request to execute a set of operations against a foreign dataset to generate a GUI element. The method includes requesting a data provider to transmit a copy of the foreign dataset, and receiving, from the data provider, the foreign dataset. The method includes submitting, to a first endpoint, a second request providing the foreign dataset as input to the first endpoint, and submitting, to a second endpoint, a third request providing first modified data, received from the first endpoint, as input to the second endpoint. The method includes receiving, from the second endpoint, second modified data, and performing at least one operation to generate the GUI element based on the second modified data.
