Convert JSON to Binary & Write to Disk

This n8n workflow provides a simple yet effective solution for writing JSON data to disk when using the Write Binary File node, which requires binary input. It starts with a Function node generating example JSON data (customizable), followed by another Function node that converts the JSON to base64-encoded binary data. Finally, the Write Binary File node saves it as 'test.json' on the local filesystem. The key benefit is overcoming n8n's limitation where JSON and binary data types don't mix sea
