The Scenario
You ran a membership promo last month and capped the coupons at a 14-day window. Forty of those coupons are still active — real members who haven't used them yet — and someone in leadership just decided to extend the promotion by 30 days to hit a subscriber target before the quarter closes. The coupon IDs and the new expiry dates are already in a Google Sheet. What isn't in the sheet is 30 minutes of your day, which is roughly what it would take to update these one at a time in Payhip's UI.
The bad version:
- Open the Payhip coupon manager, search for the first coupon ID from your sheet, click into it, and change the expiry date.
- Save, go back to the list, find the next coupon ID, repeat.
- Realize around coupon 15 that you're also supposed to reset the usage limits — which means you need a second pass through all 40 records.
This is the kind of task that makes people build workarounds they never delete. The coupon IDs are right there in the sheet. The new dates are right there in the sheet. The act of getting them from one place to the other should not require 40 round trips through a UI.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads the sheet, understands the structure, and updates your Payhip coupons directly. No manual navigation, no modal-clicking loop.
Update each Payhip coupon in column A of the "Promo Extensions" sheet: set the expiry date to the value in column B and the usage limit to the value in column C.
What You Get
- Every coupon in column A is updated in Payhip with the new expiry date from column B and the new usage limit from column C.
- A status column written back to the sheet confirming which coupons were updated and flagging any that returned an error (coupon not found, invalid date format, etc.).
- Both fields — expiry and usage limit — updated in a single pass, not two.
What If the Data Is Not Quite Ready
The expiry dates are in different formats across rows
Normalize the dates in column B of the "Promo Extensions" sheet to YYYY-MM-DD format, then update each Payhip coupon in column A with the normalized expiry date and the usage limit in column C. Write the update status into column D.
Some rows should only extend the expiry, not touch the usage limit
For rows in the "Promo Extensions" sheet where column C is blank, update only the expiry date for the Payhip coupon in column A using column B. For rows where column C has a value, update both expiry and usage limit. Write the result into column D.
The update data is split across two tabs — one for course coupons, one for membership coupons
Update Payhip coupons using data from both the "Course Updates" tab (columns A = coupon ID, B = new expiry, C = new usage limit) and the "Membership Updates" tab (same structure). Write confirmation status into column D of each tab.
You want to verify the coupon is still active before updating, then update, then log everything
For each coupon ID in column A of the "Promo Extensions" sheet, check whether the coupon is still active in Payhip. If it is, update the expiry date to column B and usage limit to column C. If it's expired or not found, write "Skipped" with the reason into column D. Write "Updated" for successful changes.
One prompt handles the pre-check, the update, and the audit trail together.
