Analyze natively.\n- You will also receive an `allowed_tags` array (may be empty).\n\nGeneral rules:\n- Analyze each feedback independently.\n- Detect and describe emotional tone naturally.\n- Identify one **primary emotion** that captures the dominant feeling.\n- Optionally include up to two **secondary emotions** that reflect additional nuances.\n- Output must be a **valid JSON array** only, with **no extra text** before or after.\n- Maintain the original input order.\n\n⚠️ CRITICAL TAGGING RULES (2-tier system with STRONG preference for allowed_tags):\n\n**TIER 1: ALWAYS TRY ALLOWED TAGS FIRST (Your Primary Responsibility)**\n- If `allowed_tags` is provided, you MUST thoroughly examine it for matches.\n- **Be creative and flexible in matching:**\n  - Look for direct matches (e.g., \"Bug\" for bug reports)\n  - Look for semantic matches (e.g., \"Payment\" tag for \"billing issue\" feedback)\n  - Look for category matches (e.g., \"Performance\" for \"slow\", \"lag\", \"loading\")\n  - Look for broader themes (e.g., \"User Experience\" for usability complaints)\n- **Think broadly:** A tag doesn't need to be a perfect word-for-word match.\n- Consider the **intent and topic** of the feedback, not just exact keywords.\n- Return up to **3** most relevant tags from `allowed_tags` (sorted by relevance).\n- **Only proceed to Tier 2 if you genuinely cannot find ANY relevant match** after careful analysis.\n\n**TIER 2: AI-Generated Tags (ONLY as a last resort)**\n- Use this ONLY when:\n  - `allowed_tags` is completely empty, OR\n  - After thorough analysis, absolutely NO tag in `allowed_tags` relates to the feedback topic\n- Generate up to **2 custom, descriptive tags** (short labels like \"UI Bug\", \"Pricing Question\").\n- Put these in `ai_tag_1` and `ai_tag_2`.\n- Use \"\" for empty AI tag fields.\n\n**Decision Flow:**\n1. Read the feedback carefully\n2. Review ALL allowed_tags thoroughly\n3. Can you match any tag semantically or thematically? → YES = Use allowed tags, set ai_tag_1=\"\", ai_tag_2=\"\"\n4. Still no match after careful review? → Use AI tags as fallback\n\nSentiment scale (choose one):\n[\"Very Negative\", \"Negative\", \"Neutral\", \"Positive\", \"Very Positive\"].\n\nEmotions:\n- primary_emotion: one clear emotional label (e.g., \"anger\", \"hope\", \"disappointment\", \"relief\", \"satisfaction\", \"gratitude\").\n- secondary_emotion: optional supporting emotional state (e.g., \"frustration\", \"trust\", \"curiosity\", \"anxiety\"). Use \"\" if none applies.\n\nResponse JSON schema (use exactly these keys):\n[\n  {\n    \"row_number\": <row_number from input>,\n    \"tags\": [\"tag_from_allowed_list_1\", \"tag_from_allowed_list_2\"],\n    \"ai_tag_1\": \"\",\n    \"ai_tag_2\": \"\",\n    \"sentiment\": \"Positive\",\n    \"primary_emotion\": \"Gratitude\",\n    \"secondary_emotion\": \"Relief\"\n  }\n]\n\nExamples of GOOD matching behavior:\n✅ Feedback: \"The app crashes constantly\" + allowed_tags: [\"Bug\", \"Stability\", \"Feature\"] → tags: [\"Bug\", \"Stability\"]\n✅ Feedback: \"Can't complete checkout\" + allowed_tags: [\"Payment\", \"Technical Issue\", \"UI\"] → tags: [\"Payment\", \"Technical Issue\"]\n✅ Feedback: \"Love the new design!\" + allowed_tags: [\"Design\", \"Positive Feedback\", \"UI\"] → tags: [\"Design\", \"Positive Feedback\"]\n✅ Feedback: \"Too expensive for what it offers\" + allowed_tags: [\"Pricing\", \"Value\", \"Feature Request\"] → tags: [\"Pricing\", \"Value\"]\n\nExamples of when to use AI tags:\n❌ Feedback: \"Bug in login\" + allowed_tags: [] → tags: [], ai_tag_1: \"Authentication Bug\", ai_tag_2: \"Login\"\n❌ Feedback: \"Need dark mode\" + allowed_tags: [\"Pricing\", \"Support\", \"Payment\"] → tags: [], ai_tag_1: \"Feature Request\", ai_tag_2: \"UI Customization\"\n\nConstraints:\n- **STRONGLY PREFER allowed_tags** - exhaust all matching possibilities first\n- Do **not** invent tags in the `tags` array — only use exact names from `allowed_tags`\n- Generate creative tags for `ai_tag_1` and `ai_tag_2` ONLY when truly necessary\n- Use ASCII keys exactly as shown. Values must be strings or arrays of strings\n- Do not include reasoning, markdown, or comments — **JSON array only**"

Duplicate the provided [Google Sheet template](https://docs.google.com/spreadsheets/d/1y7B3u5vgQLDidf-NdfPgAiBuQxP9Qa7RvdgsTPG14Fs/edit?usp=sharing).\n2. Connect your **Google Sheets** and **OpenAI** credentials in n8n.  \n3. Update the Sheet URLs in the **Fetch Allowed Tags**, **Fetch New Feedbacks**, and **Update Google Sheet** nodes.  \n4. Run manually with the **Manual Trigger** or enable the **Schedule Trigger** (runs every 60 minutes).  \n\n---\n\n### 🎨 How to Customize  \n- Adjust the **System Prompt** in the \"Tag Feedbacks with AI\" node to change tagging rules.  \n- Edit the **batch size** (default: 10) in the \"Process Feedbacks in Batches\" node for performance optimization.  \n- Change the **schedule interval** in the \"Schedule Trigger\" node (default: 60 minutes).  \n- Extend the workflow to send results to Notion, Slack, or Airtable for real-time reporting.\n\n---\n\n#### 💡 Example Use Case\nIdeal for product and research teams who collect customer feedback and want to categorize it automatically into clear, actionable topics with sentiment and emotional insights."
