Extract Product Info from Website Screenshots
Adds a product URL to your sheet and Dumpling AI extracts name, price, discount, and rating from the screenshot.
What it does
Add a product URL to your Google Sheet, and Dumpling AI instantly extracts the name, price, discount, and rating from the website screenshot. This process captures visual data that traditional tools often miss, delivering structured information directly into your sheet for immediate analysis.
Step by step
- Configure a Google Sheets trigger to watch for new rows in the target spreadsheet.
- Set up an HTTP request node that sends the page URL to Dumpling AI's screenshot endpoint.
- Parse the JSON response from Dumpling AI to retrieve the base64 encoded image string or direct image URL.
- Map the extracted fields (name, price, discount, rating) back to specific columns in the Google Sheet.
Where the LLM does the work
- Design a precise system prompt that instructs the vision model to ignore decorative elements and focus only on structured product data.
- Handle ambiguous pricing formats by asking the LLM to normalize currency symbols and decimal places into a standard format.
- Instruct the LLM to output valid JSON so the downstream workflow can reliably parse the results without manual intervention.
Watch out for
Google Sheets has row limits for API writes, so batch updates or use a queue if processing large volumes of URLs simultaneously.
Anti-bot measures might block Dumpling AI's headless browser, so rotate user agents or use proxy services to maintain consistent capture success.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Extract Product Info from Website Screenshots: Adds a product URL to your sheet and Dumpling AI extracts name, price, discount, and rating from the screenshot. ## Specification - What it does: Add a product URL to your Google Sheet, and Dumpling AI instantly extracts the name, price, discount, and rating from the website screenshot. This process captures visual data that traditional tools often miss, delivering structured information directly into your sheet for immediate analysis. - Trigger: Triggered by an event (Event · on new row in Google Sheets) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Google Sheets: Store product URLs and store extracted results - Dumpling AI: Capture screenshots and extract visible product details via visual AI - HTTP Request: Communicate with external APIs for screenshot and extraction tasks ## Known pitfalls, handle each one explicitly in your implementation 1. Google Sheets has row limits for API writes, so batch updates or use a queue if processing large volumes of URLs simultaneously. 2. Anti-bot measures might block Dumpling AI's headless browser, so rotate user agents or use proxy services to maintain consistent capture success. ## Reference implementation https://n8n.io/workflows/5169 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Spreadsheet than Google Sheets?
Yes. Google Sheets is only the example spreadsheet in this recipe. The same flow works with Airtable, Baserow and Excel. Swap the spreadsheet connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
