Merge Walmart Marketplace and Reverb 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 Walmart Marketplace and Reverb exports don't line up

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.
Reverb: an order date column specific to the marketplace's order dashboard; item price, shipping, and Reverb's selling fee as separate columns, often with international currency conversion involved; an order number distinct per listing sold. Also, used mostly for musical instruments/gear, so price ranges and shipping costs vary far more per row than typical retail exports.

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.
