# Publish operations

Operations that send the result out, as a file, a table or a message. Among them are writing files such as CSV, JSON, Parquet and Excel, loading a database, uploading to cloud storage, sending to a web endpoint, a stream or an application's API, rendering a report or chart, and sending an email or chat alert. None of them hands a new table to the next step.
