The Scenario
You're the sales ops coordinator at a call center and the Excel workbook with 1,500 phone numbers just landed in your inbox from three different lead sources — a webinar form, a data vendor, and a rep's manual entry log. The dialing campaign kicks off Monday.
Column A is chaos. Some numbers have country codes, some don't. Some have dashes. Some have parentheses. Your call center manager needs to know which ones are valid mobile lines and what carrier they belong to before the campaign starts — so the predictive dialer is calibrated correctly.
The bad version:
- Export column A to CSV, upload to a phone validation tool, wait for results
- Download results, discover the tool output a flat list with no row position — just the phone number and result — and you can't match it back to the original workbook rows because of the formatting differences
- Normalize all 1,500 numbers by hand, re-export, re-run
The campaign is in three days. You've already spent one of them on this.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook. Through its built-in Neutrino integration, it normalizes the formatting and runs phone validation on every row in column A — returning validity, number type, and carrier into the columns you specify.
Validate each phone number in column A using Neutrino and put valid (TRUE or FALSE) in column B, the number type (mobile, landline, or voip) in column C, and the carrier name in column D. Normalize formatting differences before validation.
What You Get
- Column B: TRUE or FALSE for every row
- Column C: number type — mobile, landline, or voip
- Column D: carrier name
- Formatting normalization happens before validation so mixed-format data doesn't cause false negatives
What If the Data Is Not Quite Ready
Some rows have two phone numbers in the same cell
For each row in column A, if the cell contains two phone numbers separated by a slash or comma, take the first one, validate it with Neutrino, and write the result to columns B, C, and D. Flag any row where a second number was present with MULTI in column E.
You want to filter to only confirmed mobile numbers before the campaign
Validate all phone numbers in column A with Neutrino. Write the number type in column B and carrier in column C. Then delete all rows where column B is not mobile and add a summary note showing how many rows were removed.
You need to separate by country before validation
For each phone number in column A, identify the country code and write it in column B. Then validate each number with Neutrino and write valid/invalid in column C, number type in column D, and carrier in column E.
Full dialing-list prep in one shot
Normalize all phone numbers in column A, remove duplicates, validate each with Neutrino, write valid/invalid in column B, number type in column C, carrier in column D, and produce a summary at the bottom showing the count of mobile, landline, voip, and invalid numbers found.
