Capture Website Screenshots via Google Sheets
New URL row in Sheets? The agent captures a screenshot using CustomJS and saves it to Drive named after the site title.

What it does
You get automatic visual records for every new website URL added to your Google Sheet, with screenshots saved directly to Drive and named after each site's title. This process runs instantly using CustomJS PDF Toolkit whenever a new row appears in your sheet.
Step by step
- Configure the Google Sheets trigger to watch for new rows in a specific spreadsheet and sheet tab.
- Set up the CustomJS node with code that utilizes a headless browser library like Puppeteer or Playwright to render the URL.
- Connect the output of the screenshot generation step to the Google Drive upload action, mapping the image buffer as the file content.
- Ensure the Google Sheets column containing the filename is passed through to the Drive node for consistent naming.
Where the LLM does the work
- Generate the JavaScript code for the CustomJS node that handles the asynchronous screenshot capture and error handling logic.
- Draft the specific Puppeteer or Playwright configuration settings, such as viewport dimensions and wait conditions, tailored to modern dynamic websites.
- Write the error recovery script that logs failed captures back into a dedicated status column in Google Sheets for manual review.
Watch out for
Headless browsers often fail on sites requiring login or CAPTCHA verification so you must whitelist known public URLs or implement session cookies.
Google Drive API quotas can be exceeded by rapid bulk uploads so add a small delay between upload attempts to avoid throttling errors.
Dynamic content like lazy-loaded images may not render in time for the screenshot so configure explicit wait-for selectors before capturing.

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 Capture Website Screenshots via Google Sheets: New URL row in Sheets? The agent captures a screenshot using CustomJS and saves it to Drive named after the site title. ## Specification - What it does: You get automatic visual records for every new website URL added to your Google Sheet, with screenshots saved directly to Drive and named after each site's title. This process runs instantly using CustomJS PDF Toolkit whenever a new row appears in your sheet. - 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: - n8n: Workflow orchestration and automation logic - Google Sheets: Trigger source containing website URLs and titles - CustomJS PDF Toolkit: Capturing screenshots of specified URLs - Google Drive: Storing the generated screenshot files ## Known pitfalls, handle each one explicitly in your implementation 1. Headless browsers often fail on sites requiring login or CAPTCHA verification so you must whitelist known public URLs or implement session cookies. 2. Google Drive API quotas can be exceeded by rapid bulk uploads so add a small delay between upload attempts to avoid throttling errors. 3. Dynamic content like lazy-loaded images may not render in time for the screenshot so configure explicit wait-for selectors before capturing. ## Reference implementation https://n8n.io/workflows/3332 (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 Automation Platform than n8n?
Yes. n8n is only the example automation platform in this recipe. The same flow works with Home Assistant. Swap the automation platform 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.
Who it's for
Built for Ops-IT teams who need one more recurring task off a human's plate.
Developers can adapt this to their own repo or ticket queue with the same trigger and tools.
