Merge Shopify and Walmart Marketplace Sales Data for QuickBooks Import

QuickBooks expects a consistent column layout for imported transactions — mismatched headers between channels usually mean manual cleanup before import.

Why Shopify and Walmart Marketplace exports don't line up

Shopify: a Created At timestamp that includes a timezone offset; a single Total column that already nets out discounts, with tax broken out separately; an order Name like #1001 rather than a numeric ID. Also, exports one row per line item by default, so an order with 3 products becomes 3 rows unless you export the summary report instead.
Walmart Marketplace: an Order Date column separate from the ship-by date; item price and a separate Walmart referral fee; a numeric Purchase Order ID. Also, each order line can appear as its own row with a repeated order ID, similar to Shopify's line-item export.

For quickbooks import, that mismatch is exactly what causes hours of manual cleanup every period.

FAQ

Does this upload my sales data anywhere?

No. Everything runs in your browser using JavaScript — your files are never sent to a server.

Does it work for more than two channels?

Yes. Add as many source files as you want; each distinct file layout is mapped once and remembered.
