# Edit Workflow JSON

In addition to building workflows in the visual editor, a workflow can be configured in JSON for advanced control.

If you are working with a recently released or custom block, you may need to use the JSON Editor to fully configure it. This is an advanced feature, we recommend using the visual editor for most cases.

To use the JSON editor, click on the left sidebar of the Workflow editor with the arrow pointing right. A window will appear in which you can edit the JSON of a Workflow:

The JSON Editor consists of three core components: the workflow inputs, steps, and outputs. Each of the input definitions corresponds to a workflow input, the steps to the workflow blocks, and the outputs to the fields returned by the workflow.
