The Scenario
You are a membership site owner. You have 600 subscribers in Kit. You also have an Excel workbook from your billing system — the Members tab has subscriber email in column A and membership tier in column B: Free, Pro, or Enterprise.
Your billing system just updated. Tiers shifted. Forty people upgraded, twenty downgraded, fifteen are new. You need every one of those 600 Kit subscribers to carry the right tag before the monthly members-only email goes out.
The bad version of this Tuesday:
- You export your Kit subscriber list as CSV
- You open it in Excel alongside the billing workbook
- You use VLOOKUP to match tiers to emails
- You discover Kit's CSV import does not apply tags to existing subscribers — it only creates new records
- You look up the Kit API documentation
- You start writing a Power Automate flow, realize it only handles new rows, abandon it
- The members-only email goes out with wrong segments.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the Members tab and calls Kit's API to tag each subscriber directly, no scripting, no export-and-reimport.
Open the SheetXAI sidebar and type:
For each row in the Members tab, find the Kit subscriber by the email in column A and apply the tag from column B. If the tag does not exist in Kit, create it first. Log "tagged," "subscriber not found," or "error" in column C for each row.
SheetXAI goes through all 600 rows, looks up each subscriber in Kit, applies the tier tag, creates the tag if it is missing, and logs the result. Six hundred rows done in one prompt.
What You Get
Every subscriber tagged with their current membership tier, with a status log you can filter:
- Free, Pro, Enterprise tags applied per subscriber from column B
- Tag auto-creation — any tier label not yet in Kit gets created before it is applied
- Status in column C — "tagged," "subscriber not found," or "error" for each row
The "subscriber not found" rows matter. If someone in your billing workbook is not in Kit yet, you know immediately rather than discovering the gap after the email goes out.
What If the Data Is Not Quite Ready
Billing exports are rarely perfectly aligned with Kit. SheetXAI handles the discrepancies inline.
When tier labels in the workbook do not match Kit tag names
Your billing system exports "free_plan," "pro_plan," and "enterprise_plan." Your Kit tags are "Free," "Pro," and "Enterprise."
Map the tier values in column B of the Members tab before tagging: treat "free_plan" as "Free," "pro_plan" as "Pro," and "enterprise_plan" as "Enterprise." Then tag each Kit subscriber in column A with the mapped tier value and log results in column C.
When some rows have the same email twice
Your billing export has duplicates — the same subscriber appears once as an upgrade and once with their old tier.
Deduplicate the Members tab by email in column A, keeping the row with the higher tier (Enterprise > Pro > Free). Then tag each Kit subscriber with the resulting tier from column B and log results in column C.
When you need to remove old tier tags before applying new ones
Subscribers have accumulated multiple tier tags over time. You want each one to carry only their current tier.
For each subscriber in column A of the Members tab, remove any existing tier tags (Free, Pro, Enterprise) from their Kit record first, then apply the current tag from column B. Log the result in column C.
When you also need to enroll Pro and Enterprise subscribers in a sequence
Same tagging operation, but Pro and Enterprise members should also be added to the Pro Onboarding Kit sequence.
For each row in the Members tab, tag the Kit subscriber in column A with their tier from column B. For any subscriber whose tier is Pro or Enterprise, also subscribe them to the Kit sequence named Pro Onboarding. Log "tagged," "tagged + sequence," or "error" in column C.
The pattern: tagging and conditional sequence enrollment happen in the same prompt, not two separate operations.
Try It
Get the 7-day free trial of SheetXAI and open any workbook where a column tells you what tag a subscriber should carry in Kit, then ask SheetXAI to apply them. The Kit integration is included in every SheetXAI plan. For the cleanup side, see how to bulk remove Kit tags from an Excel workbook or the Kit in Excel overview.
