The Scenario
You're an e-commerce analyst and someone on the growth team just handed you a Google Sheet with 800 international customer addresses across 40 countries. The request: verify them, standardize the format, and add latitude and longitude for a shipping-cost model that needs geocoordinates. The request landed in your inbox this morning. The model presentation is Thursday.
The bad version:
- You look at the sheet and realize country names are inconsistent — some rows say "United Kingdom," some say "UK," some say "GB." You spend an hour normalizing the country column before you can even start.
- You call the PostGrid international API in batches via a script you write by hand, but geocoding is an additional parameter you forget to enable on the first run, so you have to run the whole batch again.
- The output file has columns in a different order from your original sheet, so you spend another hour aligning the lat/lng values to the correct rows before you can hand it off.
Thursday is closer than it looks, and this was supposed to be a quick task.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads the international address data, calls PostGrid Verify with geocoding enabled, and writes the standardized address and coordinates back to the right columns without a separate normalization step or manual alignment.
Verify each international address in columns A through E (street, city, country, and postal code) using PostGrid international address verification and write the standardized address, country code, and geocoordinates (latitude and longitude) into columns F through J.
What You Get
- Column F receives the standardized, PostGrid-formatted international address.
- Column G receives the ISO country code.
- Columns H and I receive latitude and longitude respectively.
- Column J receives the verification status.
- Rows that cannot be verified are flagged rather than left blank.
What If the Data Is Not Quite Ready
Country names are inconsistent across rows
Verify each international address in columns A through E — normalize country names to ISO 3166-1 alpha-2 codes before calling PostGrid. Write the standardized address, corrected country code, latitude, and longitude into columns F through I. Flag any address that fails verification with FAIL in column J.
Addresses from a specific region need separate handling
Verify all international addresses in this sheet using PostGrid — for rows where column C is United States or Canada, use the domestic verification endpoint. For all other countries, use the international endpoint with geocoding. Write status, standardized address, latitude, and longitude into columns F through I.
Multiple tabs hold addresses for different regions
Verify international addresses in column A of both the APAC and EMEA tabs using PostGrid with geocoding enabled. Write standardized address, lat, and lng back to columns B, C, and D of each respective tab. Leave existing data in other columns untouched.
Full prep pass before handing off to the shipping model
For each row in this sheet: if the country name in column C does not match a recognized ISO country name, flag it as UNKNOWN COUNTRY in column K and skip verification. For all other rows, verify using PostGrid international with geocoding and write the standardized address into column F, country code into G, latitude into H, longitude into I, and verification status into J. Write the total count of UNKNOWN COUNTRY rows into cell L1.
One prompt handles country normalization, conditional verification, geocoding, writeback, and count — rather than a script, a manual alignment step, and a separate flag pass.
