Abstract: Technology is disclosed herein for the integration of spreadsheet environments with LLM services. In an implementation, an application receives a natural language input from a user associated with a spreadsheet hosted by the application. The application generates a prompt that includes metadata about the spreadsheet and identifies a required format for descriptions of pivot tables. The application sends a prompt to a large language model (LLM) service to elicit a reply that includes a description of the pivot table having the required format. The application receives a reply to the prompt from the LLM service that includes the description of the pivot table in the required format. The application generates pivot table according to the reply from the LLM service.
