The Scenario
Your agency's QA lead has 50 client site URLs in the "Launch Checklist" worksheet, column A. The launch is in 72 hours. The client signed off on designs built for mobile-first traffic, and nobody has verified what any of these pages actually look like on a phone screen.
Someone sent a Slack message three days ago asking for mobile screenshots. No one responded. Now it is your problem.
The bad version:
- Open Chrome DevTools on your laptop, switch to device emulation mode, paste each URL, wait for the page to render in mobile view, screenshot the viewport manually, save the file with a name that makes sense, upload it somewhere the team can see it
- Repeat for all 50 URLs, keeping track of which device preset you used so the screenshots are consistent, because the client will ask
- Discover partway through that six URLs redirect to the desktop version and bypass the device emulation entirely, meaning your "mobile" screenshots are actually desktop renders, and you have to redo those six
It takes a full afternoon. The launch prep for the other 44 items on the checklist waits.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, understands the data structure, and calls Serpdog's device emulation API on your behalf — no DevTools, no tab juggling. Open the sidebar and give it this:
For each URL in column A of the "Launch Checklist" worksheet, use Serpdog to capture a mobile-emulated screenshot and write the resulting screenshot URL into column B
What You Get
- Column B fills with Serpdog image URLs representing mobile-view renders of each URL in column A
- Rows where the URL fails to render correctly get an error note in column B rather than a silent blank
- The "Launch Checklist" worksheet structure stays intact — no extra columns touched, no rows reordered
- All 50 captures run without you managing a single browser tab
What If the Data Is Not Quite Ready
Some URLs in column A are staging URLs that require a VPN and will time out
For each URL in column A of the "Launch Checklist" worksheet that starts with "https://client-staging", skip the Serpdog capture and write "Staging — skip" into column B. For all other URLs, capture a mobile-emulated screenshot and write the image URL into column B
You want dark mode mobile screenshots for a subset flagged in column C
For each URL in column A of the "Launch Checklist" worksheet where column C says "dark mode", use Serpdog to capture a mobile screenshot in dark mode and write the image URL into column B. For all other rows, capture a standard mobile screenshot and write the image URL into column B
URLs are listed across three separate worksheets — one per site section — and you need mobile screenshots for all of them
Capture a mobile-emulated screenshot via Serpdog for each URL in column A across the "Header Pages", "Product Pages", and "Footer Pages" worksheets, and write the screenshot URL into column B on each respective worksheet
You need the screenshot, plus a flag for whether the viewport looks broken based on whether Serpdog returns an error
For each URL in column A of the "Launch Checklist" worksheet, use Serpdog to capture a mobile-emulated screenshot — write the screenshot URL into column B and "Pass" into column C if it succeeds, or write the error message into column B and "Review" into column C if it fails
Asking for the conditional logic and the capture in one prompt means you get an actionable output instead of a list of images you have to manually triage.
Try It
Get the 7-day free trial of SheetXAI and open any Excel workbook with a URL list your team needs checked on mobile — pre-launch audits, responsive design QA, client deliverables — and ask SheetXAI to run the Serpdog mobile captures. For desktop screenshot captures, see the desktop screenshots spoke, or return to the Serpdog hub.
