Preview Output
Visualize the output of any node directly in the editor.
The Preview Output node renders the output of any upstream node so you can inspect it without leaving the editor. It's the primary tool for debugging and verifying your flow at each step.
It accepts any data type — tables, images, text, JSON, predictions — and renders it appropriately.
Configuration
| Field | Options | Description |
|---|---|---|
| Display Mode | auto, table, image, text, json | How to render the output. auto detects the format automatically. |
Input
| Input | Description |
|---|---|
data | Any output from an upstream node (required) |
The Preview Output node has no outputs — it is a terminal node.
Tips
- Place Preview Output nodes after each major step while building a flow to debug as you go — remove or keep them when done
- Use
automode for most cases; switch to a specific mode if the automatic detection isn't rendering correctly - You can connect the same upstream node to multiple Preview Output nodes to inspect different output handles simultaneously (e.g. both
