5. Configure Output Language: Manually edit the "Set Variables" Node.
6. Test workflow with manual execution
7. Activate the workflow

Part 2: Google Sheets Function

1. Open Google Sheet → Extensions → Apps Script
2. Paste this code:

function BRIGHTDATA(prompt, source) {
  if (!prompt || prompt === "") {
    return "❌ Must enter prompt";
  }
 
  source = source || "google";
 
  // Update with YOUR webhook URL
  const N8N_WEBHOOK_URL = "https://your-n8n-domain.com/webhook/brightdata-search";
  
  // Update with YOUR password
  const API_KEY = "12312346";
 
  let spreadsheetId, sheetName, cellAddress;
 
  try {
    const sheet = SpreadsheetApp.getActiveSheet();
    const activeCell = sheet.getActiveCell();
    spreadsheetId = SpreadsheetApp.getActiveSpreadsheet().getId();
    sheetName = sheet.getName();
    cellAddress = activeCell.getA1Notation();
  } catch (e) {
    return "❌ Cannot identify cell";
  }
 
  const payload = {
    prompt: prompt,
    source: source.toLowerCase(),
    context: {
      spreadsheetId: spreadsheetId,
      sheetName: sheetName,
      cellAddress: cellAddress,
      timestamp: new Date().toISOString()
    }
  };
 
  const options = {
    method: "post",
    contentType: "application/json",
    payload: JSON.stringify(payload),
    muteHttpExceptions: true,
    headers: {
      "Accept": "text/plain",
      "key": API_KEY
    }
  };
 
  try {
    const response = UrlFetchApp.fetch(N8N_WEBHOOK_URL, options);
    const responseCode = response.getResponseCode();
   
    if (responseCode !== 200) {
      Logger.log("Error response: " + response.getContentText());
      return "❌ Error " + responseCode;
    }
   
    return response.getContentText();
   
  } catch (error) {
    Logger.log("Exception: " + error.toString());
    return "❌ Connection error: " + error.toString();
  }
}

function doGet(e) {
  return ContentService.createTextOutput(JSON.stringify({
    status: "alive",
    message: "Apps Script is running",
    timestamp: new Date().toISOString()
  })).setMimeType(ContentService.MimeType.JSON);
}

1. Update N8N_WEBHOOK_URL with your webhook
2. Update API_KEY with your password
3. Save (Ctrl+S / Cmd+S) - Important!
4. Close Apps Script editor

🎨 Customization

Easy Tweaks

• AI Models - Switch to GPT-4o for better optimization

• Speed - Optimize AI prompts to reduce time
• Language - Change prompts for any language

Advanced Options

• Implement rate limiting
• Add data validation
• Create async mode for long queries
• Add Slack notifications

---

🚀 Pro Tips

• Be Specific - "What is iPhone 15 Pro 256GB US price?" beats "What is iPhone price?"
• Speed Matters - Keep prompts concise (30s timeout limit)
• Monitor Costs - Track Bright Data usage
• Debug - Check workflow logs for errors

---

⚠️ Important Notes

• Timeout: 30-second Google Sheets limit (aim for <20s)
• Plain Text Only: No JSON responses
• Costs: Monitor Bright Data at console.brightdata.com
• Security: Keep API keys secret
• No Browser Storage: Don't use localStorage/sessionStorage

---

🔧 Troubleshooting

Error	Solution
"Exceeded maximum execution time"	Optimize AI prompts or use async mode
"Could not fetch data"	Verify Bright Data credentials
Empty cell	Check n8n logs for AI parsing issues
Broken characters	Verify UTF-8 encoding in webhook node
