What file does the viewer expect?

A full n8n workflow export in JSON: the object with a nodes array and its connections. Use Download or Copy to clipboard from the workflow menu in your n8n editor — a single copied node is not enough.

Is my workflow uploaded to a server?

No. The JSON is parsed and rendered in your browser, so nothing you paste or drop leaves your device. Even so, treat exports as sensitive: n8n workflows often carry endpoint URLs and identifiers.

Can I edit or run the workflow here?

No. It is a read-only viewer. Dragging nodes only rearranges the diagram so it is easier to read; nothing is written back to your n8n instance and no workflow is executed.

Why does my export fail to render?

The most common causes are invalid JSON — a partial copy or a trailing character — and an export without a nodes array. Re-export the full workflow from n8n and try again.

Why review a workflow outside the n8n editor?

It is useful for reading a workflow you inherited, reviewing a change before importing it, or walking a client through what a flow does without giving them access to the n8n instance.

n8n Workflow Viewer

Paste an n8n workflow export and explore nodes, parameters, and connections on an interactive canvas—useful for reviews, handoffs, and sharing flows without opening the editor.

How to use this viewer

Inspect an n8n workflow export on an interactive canvas—read node parameters and connections without opening the full editor.

Export from n8n
In your n8n editor, open the workflow menu and choose Download or Copy to clipboard. You need the full workflow JSON (nodes + connections), not a partial node export.
Paste or drop the file
Paste the JSON into the text area, or drag a .json file onto the window. Invalid JSON or a file without a nodes array will show an error—fix the export and try again.
Render the canvas
Click Render workflow (or Load demo to explore a sample pipeline). Nodes appear with their connections; use Fit view if the graph is larger than the viewport.
Explore nodes
Click a node to open its detail panel (parameters, IDs, connections). Drag nodes to rearrange; pan the canvas with click-drag on empty space; zoom with the mouse wheel or the bottom toolbar.
Import another workflow
On the canvas bar, use Load another to return to the paste screen and import a different export.
