The Scenario
You are a Shopify merchant who migrated to a custom checkout six months ago. The migration severed the connection to your Mailchimp store, and 900 past orders never made it in. Post-purchase automations have been firing with no purchase history to reference.
Your Mailchimp consultant is auditing the account on Friday. She needs the order history in the store first. The export is sitting in an Excel workbook on SharePoint. It is Tuesday morning.
The bad version of the next three days:
- You download the export, open it in Excel, and look up the Mailchimp e-commerce API docs
- You discover each import needs a customer, a product, and an order record all linked together
- You start building a Power Automate flow, hit the rate limit on order three, add retry logic
- The flow runs 600 rows before a date format issue kills it
- You walk into Friday's audit with 300 orders still missing and Power Automate showing no useful error output.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your workbook that reads the order export tab and creates the orders in your Mailchimp connected store, with the Mailchimp order ID written back per row.
Open the SheetXAI sidebar and type:
For each row in the Orders tab, create an order in Mailchimp store ID in cell G1 using customer email in column A, order ID in column B, order total in column C, and product name in column D. Set currency to USD and status to shipped. Write the Mailchimp order ID into column E when created, or ERROR with the reason into column E if it fails.
SheetXAI reads all 900 rows, calls the Mailchimp e-commerce API for each order, and writes the Mailchimp order ID or a specific error back to column E. No schema research, no rate-limit retry logic.
What You Get
900 rows processed, with column E showing the outcome for each:
- Mailchimp order ID — the order exists in your store and is tied to the customer record
- ERROR — the specific failure: customer email not in the audience, invalid order total, store not found
Post-purchase automations now have history. The consultant walks in Friday and the store is current.
What If the Data Is Not Quite Ready
Order exports from custom checkouts are rarely clean. SheetXAI handles data issues and the import in the same prompt.
When order totals are formatted as currency strings instead of numbers
Your export has "$149.00" in the total column and Mailchimp expects 149.00 as a float.
Before creating orders in Mailchimp, strip the $ sign and any commas from order totals in column C of the Orders tab and convert to a number. Then create each order in Mailchimp store ID in cell G1 with customer email from column A, order ID from column B, and total from the cleaned column C. Write the Mailchimp order ID into column E.
When some orders have multiple line items in separate rows
The export has one row per line item, not one row per order. You need to consolidate before importing.
Group the rows in the Orders tab by order ID in column B. For each unique order, sum the totals in column C across all its line items and take the customer email from column A. Create one Mailchimp order per unique order ID in store ID in cell G1. Write the Mailchimp order ID into a new column next to each group.
When you want to skip orders placed by addresses not in the Mailchimp audience
Importing orders for non-subscribers is wasted API work. Filter first.
For each order row in the Orders tab, check whether the email in column A exists in Mailchimp audience ID in cell H1. If not found, skip the row and write SKIPPED into column E. If found, create the order in Mailchimp store ID in cell G1 and write the Mailchimp order ID into column E.
When the export has duplicate order IDs from a system glitch
The order management system exported some orders twice. You do not want duplicate Mailchimp orders corrupting automation history.
Deduplicate the Orders tab by order ID in column B, keeping the first occurrence. Then for each unique order, create an order in Mailchimp store ID in cell G1 using customer email from column A, order ID from column B, and total from column C. Write the Mailchimp order ID into column E or ERROR with the reason if the call fails. Write the count of removed duplicates in cell H1.
The pattern: the import prompt doubles as your data audit. Column E tells you not just what succeeded, but which rows had problems and why.
