You can also send Avro, ORC or Feather files.\n\n#### \ud83d\udd01 Reuse from Other Flows\nYou can **reuse this flow** by calling the webhook from another n8n workflow using an **HTTP Request** node.  \nMake sure to send the file as **form-data** with the field name `file`.\n\n#### \ud83d\udd0d What This Flow Does:\n- Receives the uploaded file via webhook (`file`)\n- Sends it to `{{ $env.API_BASE_URL }}` as `multipart/form-data` (field name: `file`)\n- Receives parsed data, schema, and metadata\n"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "06d3e569-8724-48f2-951f-a1af5e0f9362", "name": "Parse API Response", "type": "n8n-nodes-base.code", "position": [1280, 440], "parameters": {"jsCode": "const item = items[0];\n\n// Convert `data` (stringified JSON array) \u2192 actual array\nif (typeof item.json.data === 'string') {\n  item.json.data = JSON.parse(item.json.data);\n}\n\n// Convert `meta_data` (stringified JSON object) \u2192 actual object\nif (typeof item.json.meta_data === 'string') {\n  item.json.meta_data = JSON.parse(item.json.meta_data);\n}\n\nreturn [item];\n"}, "typeVersion": 2, "notes": "This code node performs automated tasks as part of the workflow."}], "active": true, "pinData": {}, "settings": {"executionOrder": "v1", "saveManualExecutions": true, "callerPolicy": "workflowsFromSameOwner", "errorWorkflow": null, "timezone": "UTC", "executionTimeout": 3600, "maxExecutions": 1000, "retryOnFail": true, "retryCount": 3, "retryDelay": 1000}, "versionId": "c10e1897-094e-42c6-bde9-1724972ada3e", "connections": {"651a10dc-1c91-4957-bcdd-3e55d7328f04": {"main": [[{"node": "error-handler-651a10dc-1c91-4957-bcdd-3e55d7328f04", "type": "main", "index": 0}], [{"node": "error-handler-651a10dc-1c91-4957-bcdd-3e55d7328f04-105b8ea1", "type": "main", "index": 0}], [{"node": "error-handler-651a10dc-1c91-4957-bcdd-3e55d7328f04-b79b126e", "type": "main", "index": 0}], [{"node": "error-handler-651a10dc-1c91-4957-bcdd-3e55d7328f04-0620041b", "type": "main", "index": 0}], [{"node": "error-handler-651a10dc-1c91-4957-bcdd-3e55d7328f04-db01e9c1", "type": "main", "index": 0}]]}, "42a7e623-ca11-4d38-94bb-cfb48d021a5c": {"main": [[{"node": "error-handler-42a7e623-ca11-4d38-94bb-cfb48d021a5c", "type": "main", "index": 0}], [{"node": "error-handler-42a7e623-ca11-4d38-94bb-cfb48d021a5c-9dc8e3bf", "type": "main", "index": 0}], [{"node": "error-handler-42a7e623-ca11-4d38-94bb-cfb48d021a5c-53c0994d", "type": "main", "index": 0}], [{"node": "error-handler-42a7e623-ca11-4d38-94bb-cfb48d021a5c-acb895b3", "type": "main", "index": 0}], [{"node": "error-handler-42a7e623-ca11-4d38-94bb-cfb48d021a5c-55ae5760", "type": "main", "index": 0}]]}}, "description": "Automated workflow: Convert Parquet, Avro, ORC & Feather via ParquetReader to JSON.
