The Problem With Getting Sheet Data In and Out of PostGrid Verify
You have an Excel workbook full of addresses — customer shipping records, prospect lists, donor databases, field contact exports — and before a mailing run or bulk shipment, every one of them needs to pass through PostGrid Verify. The standard path is to export the data, run the API call outside of Excel, get back a results file, and paste it back into the workbook aligned to the original rows.
PostGrid Verify handles real-time verification, batch calls up to 2,000 records, international addresses across 245+ countries, free-form parsing, and suggestion-based cleanup. But there is no native bridge between Excel and PostGrid. Every time verification needs to happen, someone builds that bridge by hand.
Below are the four paths teams take. Only the last one doesn't wear you down.
Method 1: CSV Export and Re-Import
The default for Excel users: export the address column (or columns, if street, city, state, and ZIP are split) to CSV, send that to PostGrid via the dashboard or an API client, download the verified output, and paste the results back into the workbook — aligning them to the original rows. If your workbook has multiple worksheets with address data, you do this once per sheet.
For a one-time verification of a small list, this is manageable. For anything that recurs — weekly imports from a form, monthly CRM syncs, quarterly donor cleanups — the CSV cycle becomes the job no one wants. Address data never stays clean, and each round of re-export re-import is the same amount of work as the last one.
Method 2: Power Automate
Power Automate can call the PostGrid Verify API. You can build a flow that triggers on a new or updated row in Excel Online and sends the address fields to PostGrid, writing the verification result back to the workbook.
Before you go further — are you comfortable with Power Automate connectors? With HTTP action steps, JSON parsing, and dynamic expressions? If not, this is a path that gets steep fast. You are better off reading Method 3 or 4 instead.
If you passed that gate: yes, the flow is buildable. You configure the trigger on a modified row, pass the address fields to the PostGrid endpoint via an HTTP action, parse the response body, and map the output fields back to the correct columns. It works when it works.
But it fires once per row.
Hundreds of new addresses in a weekly import means hundreds of individual HTTP calls, hundreds of run histories, and a Flow run log that becomes unreadable when row 91 fails silently and the rest keep going. Tracking down which records didn't verify requires rebuilding context from the run log.
You probably just need the verified addresses. You probably have no idea how to debug a failed HTTP step in Power Automate — and that's not a character flaw, it's just not your job. So you push the problem to whoever on your team handles Power Automate flows, and now there's a ticket in a queue somewhere while the shipment deadline moves.
And the moment you need to verify only rows missing a status in column E, or cross-reference against a lookup table on a second worksheet, you've left Power Automate's row-trigger model behind.
Method 3: The Previous Generation — Connector Add-Ons
Until recently, the best repeatable option was a category of Excel add-ins and API connector tools that let you save a field-mapping configuration and re-run it against your workbook on demand. You picked the address columns, tagged the output fields, saved the config, and ran it.
That was a real improvement over the CSV export cycle. Results were consistent. Saved configs meant the team didn't have to redo the mapping every run.
But you were still responsible for every configuration decision: which column is the street, what to do about rows with no ZIP, whether to skip rows already marked verified. The tool ran the API call. The thinking about what to pass and what to do with the result was still on you. And when someone restructured the workbook or renamed a column header, the config broke until someone fixed the field mappings.
This is the previous generation. It solved the repetition problem but moved the complexity rather than eliminating it.
The Easy Way: Using SheetXAI in Excel
There is a different way entirely. SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, understands the structure, and through its built-in PostGrid Verify integration it can verify, parse, or enrich your address data directly. No saved configs, no field mapping dialogs, no CSV export. You just ask.
Example 1: Batch-verify a full sheet of shipping addresses
Batch-verify all addresses in this sheet using PostGrid's batch endpoint — street in column A, city B, state C, ZIP D — and write the verification status and corrected postal code back into columns E and F.
SheetXAI assembles the batch call, sends it to PostGrid, and writes status and corrected postal code back to the right columns. Invalid rows get flagged with an error code in column E.
Example 2: Pull international addresses with geocoding
For each row in the Global Customers sheet of this Excel workbook, call PostGrid international address verification with geocoding enabled and write the verification status, standardized address, latitude, and longitude into the next four columns.
The pattern: instead of preparing the data first and then running the API, you describe both the source and the destination in one prompt. SheetXAI handles the multi-column assembly and the writeback inline.
Try It
Get the 7-day free trial of SheetXAI and open any Excel workbook with address data, then ask it to verify or parse a column. The PostGrid Verify integration is included in every SheetXAI plan.
