Verify International Addresses From a Multi-Country List in an Excel workbook

The Scenario

The direct-mail agency brief landed in your inbox this morning. Your global SaaS company has 600 customer addresses across AU, US, GB, and DE earmarked for a physical mailer campaign. The addresses came from three different CRM exports, each with different field formats. The agency's mail house requires every address to be verified and standardised in the format of its destination country before they'll accept the file.

The campaign prints in four days.

The bad version:

  • Split the workbook by country — four separate sheets, four separate verification workflows.
  • Run each through a country-specific verification tool, download four result files, then merge them back into a single sheet with consistent column names across all four country formats.
  • Discover that the AU sheet used "Australia" as the country value while the filter expected "AU", and 80 rows got routed to the wrong endpoint.
  • Fix the filter, re-run the AU sheet, re-merge, and re-check the column alignment.

Four days. One merge operation going wrong means starting a country segment over from scratch.

The Easy Way: One Prompt in SheetXAI

SheetXAI is an AI agent that lives inside your Excel workbook. It reads the worksheet, understands the data across countries, and through its built-in Addressfinder international integration it can route each address to the correct country endpoint and write standardised results back in one pass.

For each row in this sheet, use Addressfinder international address verification with the country in column B and the address in column C and write the verified full address to column D

What You Get

  • Column D: verified, standardised address in the format required by the destination country
  • Any row where the country in column B doesn't match a supported Addressfinder country code is flagged UNSUPPORTED in column D
  • Any address that cannot be verified against the destination country's database is flagged UNMATCHED

What If the Data Is Not Quite Ready

Country values are inconsistent — full names, ISO codes, and abbreviations mixed

Normalise the country values in column B to ISO 3166-1 alpha-2 codes before routing to Addressfinder international verification, then write the standardised address and GPS coordinates to columns C and D

You also need GPS coordinates alongside the verified address

Verify all international addresses in column A using Addressfinder and write the standardised address and GPS coordinates to columns B and C — note the country code from column D

Some rows have the country embedded in the address field rather than a separate column

For rows in column A where the country appears to be part of the address string, parse out the country, look it up against Addressfinder international verification, and write the standardised address and the detected country code to columns B and C

Normalise, verify, enrich, and flag exceptions across all four countries in one shot

For all 600 addresses: normalise country values in column B to ISO codes, verify each address using Addressfinder international verification, write the standardised address to column C and GPS coordinates to columns D and E, flag any row that returns UNMATCHED in column F, and add a summary at the bottom showing how many addresses were verified per country and how many failed

One prompt handles the normalisation, routing, enrichment, and flagging — across all four countries simultaneously.
