The Scenario
It's the morning of a bulk shipment dispatch and you have 1,800 customer shipping addresses sitting in an Excel workbook — exported from the order management system last night. Your warehouse runs a pre-dispatch address check before handing off to the carrier. Three times this month, a batch went out with bad addresses and came back as undeliverable charges on the next invoice.
The bad version:
- You export the worksheet to CSV and upload it to the PostGrid dashboard, which only accepts up to 2,000 records at a time — you're right at the limit so you have to check the count first.
- The batch finishes, you download the results, and then you spend 40 minutes realigning 1,800 rows between the results file and the original workbook to write status flags back in the right places.
- You send the results to the warehouse team via email attachment, and someone else has to re-filter the worksheet for just the invalid addresses to pull the manual review list.
The carrier window closes at 2 PM. You have a meeting at 11 and another at 1.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the sheet, assembles the PostGrid batch call, and writes verification status back to the right columns — no export, no re-alignment, no email attachment.
Use PostGrid batch address verification on all 1,800 rows in this Excel sheet and write INVALID in column G for any address that could not be verified, or OK with the corrected ZIP in column H for passing addresses.
What You Get
- Column G receives the verification flag: "INVALID" for records PostGrid could not confirm, "OK" for passing rows.
- Column H receives the corrected ZIP code for passing addresses.
- The batch runs as a single PostGrid API call, not row-by-row.
- Results land in-place, aligned to the original rows — no re-import or re-alignment step.
What If the Data Is Not Quite Ready
Some rows have addresses in a single combined column instead of split fields
Batch-verify all 1,800 addresses in this worksheet — addresses are in column A as a single string. Use PostGrid's batch endpoint to verify them and write OK or INVALID into column B, and the corrected full address into column C.
You only want to process rows that haven't been verified yet
Run PostGrid batch address verification on all rows where column G is blank — skip any row that already has a status in column G. Write verification status into column G and corrected ZIP into column H for the new rows only.
Invalid addresses need a reason code, not just a flag
Batch-verify all addresses in columns A through D using PostGrid. Write verification status into column G, corrected postal code into column H, and the PostGrid error reason into column I for any row that fails — leave column I blank for passing rows.
Full pre-dispatch check combining dedup and verification in one shot
First, flag any rows where the address in columns A through D is a duplicate of a previous row — write DUPLICATE in column J. Then batch-verify all non-duplicate rows using PostGrid and write OK or INVALID into column G with corrected ZIP in column H. Finally, write the total count of invalid addresses into cell K1.
One prompt handles deduplication, verification, status writeback, and count — rather than three separate operations.
