The Scenario
A global nonprofit is printing an annual report and mailing it to donors in 30 countries. The development director just forwarded you a Google Sheet with 1,200 international donor addresses and a note that says the printer needs a verified, clean file by next Friday. You're the operations manager. This landed on your desk three days ago along with two other urgent items.
The bad version:
- You try to process the addresses in batches through the PostGrid dashboard, but the dashboard only accepts one country format, and your sheet mixes country names, ISO codes, and a few rows with no country at all.
- You get through the first 400, download the result, re-align it to the original sheet, then realize the batch output truncated the postal codes for addresses from countries where postal codes have letters in them.
- You're now two hours in, on batch two of three, and you still have to build the manual review list from the rows that failed.
Next Friday is next Friday. The print queue is not flexible.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads the donor address data, calls PostGrid's international batch verification endpoint, and writes the result back row by row — flagging failures without you having to manage batches or re-align output files.
Batch-verify all international addresses in this sheet — country in column A, address in column B — using PostGrid's international batch endpoint and write verification status and corrected postal code into columns C and D.
What You Get
- Column C receives the verification status for each row.
- Column D receives the corrected postal code, including alphanumeric codes for countries that use them.
- Rows that fail verification are flagged with FAIL rather than left blank.
- The results are written in-place, aligned to the original rows — no re-import or re-alignment step.
What If the Data Is Not Quite Ready
Country values are inconsistent — some are full names, some are ISO codes
Batch-verify all international donor addresses in this sheet — normalize the country column to ISO 3166-1 alpha-2 format before calling PostGrid. Write verification status into column C and corrected postal code into column D. For rows where the country cannot be recognized, write UNKNOWN COUNTRY in column E.
Some rows have no country specified
Batch-verify all international addresses in this sheet using PostGrid — for rows where column A is blank, default to United States and flag them with ASSUMED US in column E. Write verification status into column C and corrected postal code into column D for all other rows.
Failed rows need an error reason, not just a flag
Run PostGrid international batch address verification on all rows in the Donors tab. Write FAIL in column E for addresses that could not be verified, the PostGrid error reason in column F, the corrected postal code in column D for passing rows, and OK in column E for passing rows. Leave column F blank for passing rows.
Complete pre-print verification pass with dedup and summary
In the Donors tab: first flag any duplicate address entries (same country and address in columns A and B) with DUPLICATE in column G. Then batch-verify all non-duplicate rows using PostGrid international and write OK or FAIL into column E, corrected postal code into column D, and error reason into column F for failing rows. Write the total verified count into cell H1 and the total failed count into cell H2.
One prompt handles deduplication, international batch verification, error reasons, and a summary count — rather than running each step as a separate operation.
