The Scenario
Your procurement security team is working through the approved supplier review. One hundred fifty vendor domains sit in column A of an Excel workbook — companies that want to be added to your approved supplier list. Policy requires a domain security check before any vendor gets through: registration age, registrar, and any known malicious flags. A domain registered 30 days ago with a privacy-protected registrar is not getting approved without a conversation.
You have the workbook. The approval committee meets on Friday.
The bad version:
- Open a WHOIS lookup tool, paste each domain one at a time, record the registration date and registrar in the workbook
- Do this 150 times, switching back and forth between the browser and Excel
- Realize at domain 75 that the WHOIS tool is returning different registrar names for the same registrar across different TLDs, and you're not sure how to normalize them
It is Wednesday afternoon. You're not done. The approval queue is still empty.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook. Through its built-in Neutrino integration, it runs domain lookups on every row in column A and writes the registration date, registrar, and security flags into the columns you specify.
For each domain in column A, run a Neutrino domain lookup and write the registration date, registrar, and any security risk flags into columns B, C, and D.
What You Get
- Column B: registration date — sortable to surface recently registered domains immediately
- Column C: registrar name
- Column D: security risk flags returned by Neutrino — malware, phishing, spam infrastructure
- All 150 domains processed in one pass
What If the Data Is Not Quite Ready
You want domains registered under 6 months ago automatically flagged
Look up all 150 domains in column A with Neutrino. Write registration date in column B and registrar in column C. Flag any domain registered less than 6 months ago as NEW DOMAIN in column D and any with security risk flags as RISKY in column E.
Domain values include paths or protocols that need stripping
For each value in column A, extract just the registered domain (strip http, https, www, and any path). Write the cleaned domain in column B. Then run Neutrino domain lookup and write registration date in column C, registrar in column D, and security flags in column E.
You need to produce a vendor-level summary for the committee
Run Neutrino domain lookup on all domains in column A. Write registration date in column C, registrar in column D, and security flags in column E. Produce a summary table showing, for each vendor in column B, their domain's registration date and whether any security flags were returned.
Full vendor vetting in one shot
Strip protocols and paths from all domains in column A, run Neutrino domain lookup on each, write registration date in column B, registrar in column C, and security flags in column D. Flag newly registered domains (under 6 months) as NEW DOMAIN in column E and any with security flags as RISKY in column F. Highlight RISKY rows red and NEW DOMAIN rows orange, then produce a summary at the bottom showing how many vendors are approved vs. flagged for review.
