What is a key step in creating a trigger to change a cell value?

Choosing the correct column and entering a new value is essential in creating a trigger to change a cell value because it directly defines what happens within the workflow. When you set up a trigger, you need to specify which column will respond to the trigger event and what new value it should reflect when the condition for the trigger is met. This action ensures that the process is automated according to the specific requirements of the project or task at hand, allowing for enhanced project efficiency and accuracy in updates.

The other options are less relevant to the specific task of setting a trigger. For example, selecting a template might be necessary when starting a new project, but it doesn't directly relate to configuring a trigger. Inviting collaborators would be relevant when sharing the workflow but does not impact the functionality of the trigger itself. Exporting the sheet before making changes is a precautionary step but is not part of the trigger creation process. Thus, focusing on the column and the new value is the critical step in setting up an effective trigger to automate cell value changes.
