The Scenario
A colleague who handled vendor onboarding left the company two months ago. You've inherited their procurement tracker — an Excel workbook — with 150 supplier contact phone numbers in column C of a worksheet called Vendors. The numbers go back three years. Some are probably disconnected. Some may belong to contacts who have since been reported for fraud. Before you add any of them to the dialler for a new sourcing push, you need to know which ones are clean.
You didn't build this workbook. You're not sure which numbers are recent and which are ancient. And there's no documentation for what any of the other columns mean.
The bad version:
- Google each number manually to see if anything suspicious comes up.
- Realize "googling a phone number" returns almost nothing useful for most numbers.
- Try to remember if your company has a CallerAPI account and who set it up, then spend 20 minutes tracking down the API key before you've looked up a single number.
150 supplier numbers. No clear path. No way to do this at scale without a system you don't currently have.
The sourcing call list can't go out with fraud-risk numbers in it — the compliance team will hold the whole campaign if they find one bad row. That's not a problem you can solve later.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook. It reads your Vendors worksheet, calls CallerAPI for each number in column C, and writes the fraud-risk classification back to the workbook — no API key hunting, no manual lookups, no tab-switching.
Look up every phone number in column C of my Vendors worksheet using CallerAPI and write the carrier name, line type, and country code to columns D, E, and F
What You Get
- Column D: carrier name for the number, or "Unknown" if CallerAPI has no record.
- Column E: line type — "mobile," "landline," or "VOIP."
- Column F: two-letter country code.
- Any number that CallerAPI cannot resolve gets "Unknown" across columns D, E, and F so nothing is silently skipped.
What If the Data Is Not Quite Ready
I also want a fraud risk label — not just carrier data
For each number in column C of my Vendors worksheet, fetch CallerAPI data and write 'Fraud Risk' in column G if FTC complaints exceed 5, 'Clean' if zero complaints, or 'Unknown' if no data is returned.
Some numbers in column C have extra whitespace or inconsistent formatting
Clean all phone numbers in column C of my Vendors worksheet — strip whitespace and normalize to E.164 format — then run CallerAPI lookups and write carrier name, line type, and country code to columns D, E, and F.
The vendor list is split between two worksheets — current Vendors and a Legacy Contacts worksheet with older entries
Look up every phone number in column C of both the Vendors worksheet and the Legacy Contacts worksheet using CallerAPI. Write carrier name, line type, and country code to columns D, E, and F in each worksheet.
I want to enrich all numbers, label fraud risk, and move the flagged rows to a separate worksheet so compliance can review them
For each phone number in column C of my Vendors worksheet, run a CallerAPI lookup. Write carrier name, line type, and country code to columns D, E, and F. Write 'Fraud Risk' to column G if FTC complaints exceed 5, 'Clean' if zero, or 'Unknown' if no data. Then move all rows where column G is 'Fraud Risk' to a new worksheet called Compliance Review.
That's enrichment, classification, and triage in one pass — rather than running three separate steps and manually moving rows.
