The Scenario
You are a Shopify store owner. You use Kit for email marketing with a custom field called ltv (lifetime purchase value) to route subscribers into different flows. Your Shopify data just refreshed. You have an Excel workbook with 900 rows — column A is customer email, column B is their current lifetime purchase value.
You need to push column B into the Kit custom field ltv for every matching subscriber before tomorrow's campaign.
The bad version of this Tuesday:
- You look up the Kit API docs for subscriber updates
- You consider writing a Power Automate flow, realize it only handles new rows, not existing subscriber updates
- You try to find a connector tool that pushes to Kit custom fields
- You find one that requires a premium plan and a week of setup
- You send the campaign without updated LTV data and the wrong subscribers get the upsell sequence.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the workbook and calls Kit's subscriber update API for each row, pushing the custom field value directly.
Open the SheetXAI sidebar and type:
For each row in this workbook, update the Kit subscriber matching the email in column A by setting the custom field ltv to the value in column B. Log "updated," "subscriber not found," or "error" in column C for each row.
SheetXAI goes through all 900 rows, looks up each subscriber in Kit, pushes the ltv value, and logs the result in column C. Nine hundred updates, one prompt.
What You Get
Every Kit subscriber profile updated with their current LTV, with a log to verify:
- ltv custom field — set per subscriber from column B
- "subscriber not found" rows — customers in Shopify who are not in Kit, flagged for review
- "updated" rows — every successful push, logged in column C
The "subscriber not found" rows matter. Customers who purchased but are not on your list are a gap worth addressing.
What If the Data Is Not Quite Ready
Purchase exports have formatting issues before they are ready to push to Kit. SheetXAI handles them inline.
When LTV values include currency symbols or commas
Column B has "$1,250.00." Kit expects a plain number.
Clean the values in column B by removing dollar signs, commas, and whitespace. Then update each Kit subscriber in column A by setting the custom field ltv to the cleaned value. Log results in column C.
When you need to update two custom fields at once
Your workbook also has a purchase_count column in column C and you want to push both fields in the same pass.
For each row, update the Kit subscriber matching column A by setting the custom field ltv to column B and the custom field purchase_count to column C. Log "updated," "not found," or "error" in column D.
When you only want to update subscribers above an LTV threshold
Filter this workbook to rows where column B is greater than 500. For those rows only, update the Kit subscriber in column A by setting the custom field ltv to column B. Log results in column C. For rows below the threshold, write "SKIPPED — below threshold" in column C.
When the workbook is a raw Shopify order export that needs aggregation before pushing
Order-level rows, not customer-level. Multiple rows per customer. You need the aggregated LTV per customer pushed to Kit.
This workbook has one row per order — column A is customer email, column B is order value. Aggregate to get total lifetime value per unique email by summing column B grouped by column A. Write the result to a new Summary tab with email in column A and total LTV in column B. Then update each Kit subscriber in the Summary tab column A by setting the custom field ltv to column B. Log results in column C of the Summary tab.
The pattern: aggregate, clean, and push to Kit in one prompt.
