AI ad copy variations for every product
Run once and get four Arabic and English ad variations for every product in your sheet, ready to test.
How it works
Trigger: Manual — you click Run
- Read your Products sheet (product, price, benefits).
- AI writes 4 ads per product from different angles, 2 Arabic and 2 English.
- Save each ad as a row in the Ad copy sheet.

Code
JavaScript used in the Code step — already included in the template below.
// Reads the AI's JSON for each product and turns every ad variation into its own row.
const out = [];
for (const item of $input.all()) {
const raw = item.json.text || "";
const data = JSON.parse(raw.slice(raw.indexOf("{"), raw.lastIndexOf("}") + 1));
(data.ads || []).forEach((ad, i) => out.push({
json: {
product: data.product,
variation: i + 1,
angle: ad.angle,
language: ad.language,
headline: ad.headline,
primary_text: ad.text,
status: "draft",
},
}));
}
return out;Build it
Pick your tool — same automation, step by step.
Copy and paste straight into an n8n canvas (Ctrl+V), or download and use Import from File. Then connect your own credentials and replace every YOUR_… placeholder. AI steps use a Claude model node — swap it for OpenAI, Gemini or Ollama if you prefer.

}In Make, create a new scenario and add these modules in order:
- Run the scenario manually (Run once)
- Google Sheets › Search Rows
- Anthropic Claude › Create a Prompt (or OpenAI › Create a Completion)
- Tools › Set variable / Iterator + Array aggregator (same logic as the Code step)
- Google Sheets › Add a Row
- Every module run uses Make operations — the free plan includes a monthly quota.
- Make's built-in functions (map, sum, formatDate…) can replace most Code steps; for complex logic use a code module.
- Module and step names can differ slightly as Make and Zapier update their apps.
In Zapier, create a new Zap and add these steps in order:
- Google Sheets — New or Updated Spreadsheet Row (Zapier has no manual trigger)
- Google Sheets — Lookup Spreadsheet Rows (or Code by Zapier)
- Anthropic (Claude) — Send Message (or ChatGPT — Conversation)
- Code by Zapier — Run JavaScript (paste the code from the Code section)
- Google Sheets — Create Spreadsheet Row
- Zaps with more than two steps need a paid Zapier plan.
- Webhooks, Filters/Paths and Code by Zapier are premium features on some Zapier plans.
- Code by Zapier runs JavaScript: reuse the code shown above, reading inputs from inputData instead of $json.
- Module and step names can differ slightly as Make and Zapier update their apps.
Tips
- Write real benefits in the sheet; the AI is told never to invent claims.
