The Scenario
You are an accounts-payable specialist. Month-end is in three days. You have 80 vendor payment rows in a Google Sheet: payee name in column A, address line in column B, city in column C, state in column D, ZIP in column E, routing number in column F, account number in column G, and dollar amount in column H.
Every vendor on that list gets a physical check this cycle. PostGrid can print and mail all of them. But PostGrid is an API, and you are an AP specialist, not a developer.
The bad version of this quarter:
- You submit a ticket to IT to build a PostGrid integration
- IT says two weeks minimum
- You fall back to printing checks one by one from the accounting system
- The printer jams at check 34
- Month-end closes and three vendors are still unpaid.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your AP sheet and calls PostGrid's cheque endpoint for you, row by row, so you do not have to write a script or wait for IT.
Open the SheetXAI sidebar and type:
For each row in the 'Payroll' sheet, create a PostGrid cheque using bank account ID bank_xyz. Payee name is in column A, address line in column B, city in column C, state in column D, ZIP in column E, routing number in column F, account number in column G, and amount in column H. Write the returned cheque ID and status back into columns I and J.
SheetXAI iterates through all 80 rows, creates a PostGrid cheque for each, and logs the cheque ID and status back to columns I and J. You have a complete record without touching a dashboard.
What You Get
80 PostGrid cheque orders, logged back to the sheet:
- Cheque ID — written to column I, one per vendor
- Status — written to column J so you can see what is queued, pending, or sent
- Audit trail — the sheet is now the ledger and the mailing record in one place
The status column is your reconciliation tool. At month-end you pull column J and every vendor with a status other than "mailed" gets a follow-up. No separate report to generate.
Need to filter first? Add "only process rows where column K says 'Approved'" to the prompt and SheetXAI skips unapproved rows without you having to hide them.
What If the Data Is Not Quite Ready
AP exports from accounting systems are rarely PostGrid-ready. SheetXAI handles the prep and the send in the same prompt.
When routing and account numbers have formatting artifacts
The export wrapped routing numbers in quotes or added dashes. PostGrid expects plain numeric strings.
Strip any non-numeric characters from column F (routing number) and column G (account number) in the 'Payroll' sheet. Then create a PostGrid cheque for each row using bank account ID bank_xyz and write the cheque ID and status into columns I and J.
When some rows are not yet approved
The sheet mixes approved and pending rows. You only want to mail approved payments.
For each row in the 'Payroll' sheet where column K says 'Approved', create a PostGrid cheque using bank account ID bank_xyz with payee from column A, address from columns B through E, routing from column F, account from column G, amount from column H. Write the cheque ID and status into columns I and J. Leave rows where column K is not 'Approved' untouched.
When amounts need to be pulled from a separate ledger tab
The AP sheet has the vendor addresses but the final approved amounts are on a separate Ledger tab.
Match each vendor row in the 'Payroll' sheet to the 'Ledger' tab by vendor name. Pull the approved amount from the Ledger tab's column C. Then create a PostGrid cheque for each matched row and write the cheque ID into column I of the Payroll sheet.
When you need to deduplicate, validate amounts, and send in one pass
The export has duplicates from a double-run, some amounts are formatted as text with dollar signs, and you only want rows marked approved.
Deduplicate the 'Payroll' sheet by payee name, keeping the row with the larger amount. Convert column H to a plain numeric value by removing the dollar sign and commas. Filter to rows where column K says 'Approved'. Then create a PostGrid cheque for each remaining row using bank account ID bank_xyz and write the cheque ID and status into columns I and J.
The pattern: one prompt handles the data work and the API calls together. You get a clean audit trail without a developer in the loop.
Try It
Get the 7-day free trial of SheetXAI and open any AP or payroll sheet, then ask it to run a PostGrid check batch. The PostGrid integration is included in every SheetXAI plan. For a related workflow, see how to send a bulk letter campaign from a sheet or the PostGrid in Google Sheets overview.
