The Scenario
The loyalty program just graduated 1,000 customers to platinum tier. The retention team has their customer IDs in an Excel workbook. Each one needs a 'platinum-member' tag added in Shopify — without overwriting the other tags they already have, like 'wholesale' or 'vip-referral' — before Friday's automated email segment runs.
The retention manager considered doing it manually. She opened the first customer profile in Shopify. She saw the existing tags. She closed the tab and sent you the workbook.
The bad version:
- Open the first customer profile, click Tags, add 'platinum-member' after the existing tags, verify the existing tags are still there, save.
- Open the next customer profile.
- 1,000 profiles. Each one a search, a click into the profile, a tag addition, a verification, and a save.
Friday's segment query filters on 'platinum-member'. If the tags aren't there, the segment doesn't run correctly. There is no fallback.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the customer IDs, fetches existing tags from Shopify, appends the new tag, and updates each record — all in one pass, without touching any other customer data.
Read my Segment Update Excel sheet and update each Shopify customer in column A to add the tags listed in column B, preserving any existing tags
What You Get
- The 'platinum-member' tag (or whatever is in column B) added to each customer's Shopify record, with all pre-existing tags preserved.
- A status written back into column C — "tagged" for each success, an error message for any customer ID that couldn't be resolved.
- Friday's email segment pulls correctly because the tags are in place before the query runs.
What If the Data Is Not Quite Ready
Some customers in the workbook already have the 'platinum-member' tag from a previous run
For each row in my Segment Update Excel sheet where column C is blank, check if the Shopify customer in column A already has the 'platinum-member' tag — add it if not — write 'tagged' or 'already tagged' into column C
The workbook uses email addresses, not customer IDs
For each row in my Segment Update Excel sheet, look up the Shopify customer by email in column A — add the tag 'platinum-member' preserving existing tags — write 'tagged' or 'not found' into column B
Different customers need different tags based on a tier column
For each row in my Segment Update Excel sheet, update the Shopify customer in column A to add the tag in column B — preserve existing tags — write 'tagged' in column C for each success
Look up by email, skip already-tagged, add tier tag from column B, and write timestamp
For each row in my Segment Update Excel sheet where column C is blank, look up the Shopify customer by email in column A — if the tag in column B is not already present, add it while preserving existing tags — write 'tagged' and the timestamp into column C, or 'already tagged' if present
Running the tag check and the update in one pass means you can safely re-run the prompt after adding new rows to the workbook without double-tagging anyone.
