The Scenario
You've been buying wholesale and reselling through your own store for four years. Your margin calculation is simple: supplier cost minus Walmart retail divided by retail equals your theoretical competitive floor. If Walmart is selling it cheaper than your supplier is charging you, the product is out.
You have 80 SKUs in column A with supplier costs in column B. You need Walmart's current retail price in column C so you can calculate margin in column D with a formula you've already written.
The bad version:
- Open Walmart.com. Search the first product name. Find the matching listing. Check whether it's sold by Walmart or a third-party marketplace seller (matters for pricing context). Copy the price. Paste into C2. Next product.
- After 20 minutes you've done 6 rows. Your supplier sent a revised price list while you were doing this, so now column B is partially outdated and you're not sure which rows to trust.
- Use the Walmart API directly. Realize you need a developer account, an approval process, and an API key before you can even test a query.
Eighty products at 3 minutes each is four hours of work. That's four hours not spent sourcing new products, negotiating with the supplier, or fulfilling the orders that are already sitting in the queue.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the product names in column A, queries Composio Search's Walmart tool for each one, and writes current retail prices and product URLs into columns C and D.
For each product name in column A, search Walmart and write the lowest current Walmart price into column C and the product URL into column D.
All 80 SKUs, current Walmart pricing, in one pass.
What You Get
- Column C: Lowest current Walmart retail price for that product name
- Column D: Direct Walmart product URL for verification
- Rows where no Walmart match is found are marked 'Not Found' in column C
- Prices reflect the Walmart-sold listing, not third-party marketplace sellers
What If the Data Is Not Quite Ready
Product names in column A are too generic for a confident match
Some names like "USB cable 6ft" return hundreds of results. You need to add the brand name from column E to narrow the search.
For each product in column A, combine the product name with the brand in column E and search Walmart for the most specific matching listing. Write the lowest Walmart price into column C and the URL into column D.
You want to check whether free shipping is available
Shipping cost changes the effective price for your margin model.
Search Walmart for each item in my grocery procurement list in column A and add the price per unit and whether free shipping is available into columns C and D.
You want to calculate margin immediately
Column B has supplier costs. Column C will have Walmart prices. Column D should have margin.
For each product name in column A, search Walmart and write the lowest current price into column C. Then calculate the margin as (column C minus column B) divided by column C, expressed as a percentage, and write it into column D. Flag any row where margin is below 20% with 'Low Margin' in column E.
Kill chain: update prices, calculate margin, sort by opportunity
For each product in column A, search Walmart for the current lowest price and write it into column C. Calculate the gross margin percentage using column B as cost and column C as price, write it into column D. Then sort all 80 rows by column D descending so the highest-margin products are at the top. Flag any row with a negative margin in column E as 'Unviable'.
One prompt pulls the prices, computes the margins, and reorders the workbook for decision-making.
