The Scenario
Third ping this week from the product team: "The 'subscription_tier' attribute we added to Formbricks last Tuesday — we still need to backfill it for the existing 1,200 contacts. The targeting for next week's survey depends on it."
The attribute exists in Formbricks. The values exist in an Excel workbook — an export from the subscription database with email in column A and tier in column B. The problem is that someone has to match each email to the right Formbricks contact and set the attribute.
The bad version:
- Look up the first email in Formbricks, find the contact, click into the attribute section, type in the tier value, save
- Repeat for contacts 2 through 1,200
- Somewhere around contact 80, you'll start making data-entry errors from sheer repetition — a wrong tier here, a skipped contact there
- Realize there's no efficient way to verify you got them all right without pulling the contacts back out and comparing
No one hired you to do this. You're doing it because the targeting can't run without it, the survey goes out next week, and it's sitting in your queue.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the email and tier columns and through its built-in Formbricks integration updates each contact's attribute in bulk — matching on email, writing the value, logging the result.
For each email in column A, update the Formbricks contact's 'subscription_tier' attribute to the value in column B
What You Get
- Each Formbricks contact matched by email and updated with the new 'subscription_tier' attribute value
- A STATUS column written per row: SUCCESS if the update completed, NOT FOUND if no Formbricks contact matched that email, ERROR with a note if the update failed
- All 1,200 rows processed in one operation — no batching configuration needed
What If the Data Is Not Quite Ready
You need to update two attributes at once
The product team added both 'subscription_tier' and 'billing_cycle' to Formbricks, and both need to be backfilled from the same export.
Bulk-update Formbricks contacts from this Excel sheet — match on email (column A) and set the 'subscription_tier' attribute to column B and 'billing_cycle' attribute to column C — write SUCCESS or ERROR into column D
Some emails in the workbook have trailing spaces or capitalization issues
The export from the subscription database isn't perfectly clean — some emails have trailing spaces or inconsistent casing.
For each email in column A, trim whitespace and lowercase the address before looking up the Formbricks contact — then update the 'subscription_tier' attribute to the value in column B and write the result into column C
You want to verify the backfill before committing
Before running the update, you want to pull the current attribute value for each contact so you can compare before and after.
For each email in column A, fetch the current value of the 'subscription_tier' attribute from Formbricks and write it into column C — then I'll review before running the update
Clean, deduplicate, update, and log in one pass
Remove any duplicate emails from column A (keep the first occurrence), skip rows where column B is blank, then update the Formbricks 'subscription_tier' attribute for each remaining contact — write SUCCESS, NOT FOUND, or ERROR into column C and print a summary at the bottom: total updated, total not found, total errors
The dedup, the validation, the update, and the audit log all happen together. The survey targeting is ready without a second pass.
