Build a Live Competitor Price-Tracking Sheet From Google Shopping Results in a Google Sheet

The Scenario

It is Sunday evening. The weekly pricing report goes to the VP of merchandising at 9 AM Monday. Your workbook has 350 SKUs. The column next to each one — "Current Competitor Low Price" — is blank, because filling it in is your job, and right now that job requires visiting Google Shopping 350 times.

The bad version:

  • Search the first product in Google Shopping, find the lowest listed price, type it into column B
  • Repeat for SKU 2, then 3, discovering around SKU 40 that some products return sponsored listings first, so your "lowest price" is actually an ad, not an organic result
  • Finish four hours later with a sheet that is already partially stale because prices updated while you were entering the early rows

The Monday report is supposed to surface pricing opportunities. Instead it surfaces how much time your team spends gathering data that could be gathered automatically.

The Easy Way: One Prompt in SheetXAI

SheetXAI is an AI agent that lives inside your Google Sheet. It reads the SKU list in column A, calls SerpApi's Google Shopping endpoint for each one, and writes the pricing data back — all 350 rows — without you opening a browser. One prompt, sent Sunday night.

Search Google Shopping for each product in column A and write the lowest price, seller, and star rating into columns B, C, and D

What You Get

  • Column B receives the lowest listed price from organic Shopping results (not sponsored)
  • Column C receives the seller name at that price
  • Column D receives the star rating if one is present, or blank if the listing has no rating
  • Products with no Shopping results get a note in column E rather than leaving the row silently empty

What If the Data Is Not Quite Ready

SKU names in column A are internal codes, not product names

Look up each SKU in column A against the product name in column B, then search Google Shopping via SerpApi using the product name and write the lowest price, seller, and rating into columns C, D, and E

You want the top 3 listings, not just the lowest

For every product in column A, pull the top 3 Google Shopping listings via SerpApi and stack the title, price, merchant, and rating for each across columns B through M

Prices come back in mixed currencies

Search Google Shopping via SerpApi for each product in column A, normalize all returned prices to USD using the exchange rate in cell B1, and write the converted price, original currency, and seller name into columns B, C, and D

Full dedup, enrich, and flag in one prompt

Remove duplicate product names from column A, search Google Shopping via SerpApi for each unique item, write the lowest price and seller into columns B and C, and flag in column D any product where our price in column E is more than 10 percent above the lowest competitor price

The pricing flag and the data pull happen in one pass — no intermediate steps.
