Runs in your browser

Import blockers

Identify invalid JSON, missing nodes arrays, missing connection maps, and duplicate node names.

Credential reminders

Spot integration nodes where the workflow may import but still fail until credentials are configured.

n8n workflow debugger FAQ

When should I use the n8n workflow debugger?

Use it when an exported workflow will not import cleanly, imported nodes do not connect correctly, or a workflow looks valid but fails before activation.

Is this different from the validator?

It uses the same local inspection engine, but this page is framed around debugging import and runtime issues. The validator is the primary general-purpose checker.

Can it test live n8n executions?

No. It reviews exported workflow JSON only. Use n8n execution logs for live runtime data after import.
