Part 2: Google Sheets Function

Open Google Sheet → Extensions → Apps Script
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);
}

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