The Scenario
You are a brand migration lead. Your company is moving platforms next Tuesday. You need 300 historical orders backfilled into Omnisend before the cutover so post-purchase flows and purchase-history segmentation work from day one.
Those 300 orders are in an Excel workbook — order ID, contact email, product list, total, currency, and created date. The workbook is clean. The deadline is not.
The bad version of this week:
- You look for an order import option in Omnisend — there is not one
- Open the API docs for the orders endpoint
- Write a script to POST each row
- Hit a schema validation error because your product list format is slightly off
- Fix it, re-run from row 47
- Realize rows 1 through 46 were already created
- Walk into the Tuesday cutover with 600 ghost orders and a cleanup task.
The fast version is one prompt and the 300 orders are in Omnisend before Friday.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the migration workbook and calls Omnisend's batch orders API so you do not have to write a script or debug schema validation errors.
Open the SheetXAI sidebar and type:
Read my Excel historical-orders workbook (300 rows with order ID, email, product list, total, currency, and created date) and bulk-create all orders in Omnisend using the batch endpoint.
SheetXAI reads the workbook, constructs the batch payload, fires the request, and confirms the job is queued. Three hundred orders, one batch, no script to debug.
What You Get
A single Omnisend batch order import covering all 300 rows:
- Order ID — used as the external identifier so re-runs do not create duplicates
- Contact email — linked to the existing contact record for correct attribution
- Products — structured from the product list column
- Total and currency — numeric, mapped correctly for multi-currency stores
- Created date — preserved so purchase history flows fire from the right baseline
The batch API treats order ID as idempotent. Omnisend will not create a duplicate if you re-run. That safety net is what you do not get from a naive POST-per-row script.
What If the Data Is Not Quite Ready
Migration workbooks pulled from old platforms always have quirks. SheetXAI handles them inline.
When the product list column has inconsistent formatting
Some rows have comma-separated names, some have JSON, some have pipe-separated values from different export tools.
Before importing, normalize the product list in column C so every row is a valid JSON array of objects with at minimum "productId" and "price." Flag any row where normalization fails by writing "FORMAT ERROR" in column F. Then run the Omnisend batch order import for the valid rows.
When some orders have no contact email
Guest checkout rows have no email. Omnisend requires one to link the order to a contact.
For any row where column B is empty, write "SKIPPED — no email" in column F and exclude that row from the batch import. Import all rows with a valid email and write the batch job ID into cell G1.
When order totals have currency symbols
The old platform exported totals as "£149.99" and Omnisend expects a plain decimal.
Strip all currency symbols from column D and convert values to plain numeric decimals. Then run the Omnisend batch order import.
When you want full validation, cleanup, and import in one shot
The workbook is raw and unreviewed. You want everything handled before a record touches Omnisend.
Validate the migration workbook: check that column A has no duplicate order IDs, column B has valid email format, column C is parseable as a product list, and column D is numeric. Write any validation failures into a new tab called "Errors" with the row number and reason. For all passing rows, run the Omnisend batch order import. Write the batch job ID into H1 and the imported vs skipped counts into H2 and H3.
The pattern: validate, clean, and import in one instruction. You walk into the Tuesday cutover with an audit trail, not a cleanup task.
Try It
Get the 7-day free trial of SheetXAI and open any order migration workbook, then ask it to run the Omnisend batch import. The Omnisend integration is included in every SheetXAI plan.
