This AI workflow has 23 nodes and runs manually, when you click “Execute workflow” (plus 1 other trigger). Along the way it connects OpenRouter Chat Model.
How it runs
Trigger: Manually, when you click “Execute workflow” (plus 1 other trigger).
- Select a Workflow (n8n): get
- Fetch All Workflows (n8n): uses n8n
- Set Target Workflow Id (Edit Fields (Set)): sets 1 field: workflow_id
- Aggregate: combines items into one
- Fetch Target Workflow JSON (n8n): get
- Form Dynamic Workflow List (n8n Form): shows the next form page
- Extract Workflow Nodes Connections (Edit Fields (Set)): sets 3 fields: old_workflow, nodes, connections
- Parse Selected Workflow Id (Edit Fields (Set)): sets 1 field: id
- Generate Node Rename Mapping (Basic LLM Chain): sends a prompt to an LLM, with model: OpenRouter Chat Model; output parser: Parse LLM Mapping ToJson
- Prepare LLM Validation Data (Edit Fields (Set)): sets 5 fields: old_workflow, nodes_name, connections_nodes_name_reference…
…plus 9 more steps. See the full node list below.
