Parse Shell Command JSON Output for n8n Workflows

This workflow demonstrates how to execute a shell command that outputs JSON data and integrate it seamlessly into an n8n workflow. It uses the Execute Command node to run a simple echo command producing JSON, then processes the stdout in two branches: one parses it into structured flow data via a Function node, and the other directly references the parsed JSON in an IF node's condition to check a boolean value.

The benefits include enabling n8n to interact with any CLI tool or script that outputs JSON without custom HTTP endpoints or file intermediaries, saving development time for self-hosted setups. It's particularly useful for developers automating local tools, testing environments, or bridging command-line utilities into broader automations.

Use cases span development workflows like running npm scripts, querying local databases via CLI, or processing git commands with JSON output. While basic, it serves as an educational template extensible to real tools like jq for complex JSON manipulation. Note: Execute Command is unavailable on n8n Cloud, limiting it to on-premise instances.

Overall, this low-complexity example highlights n8n's flexibility for OS-level integrations, making it a quick-start for power users incorporating shell outputs into no-code pipelines.
