Merge Depop and Wayfair Sales Data for Spreadsheet Automation

Automating a recurring sales spreadsheet breaks the moment a platform's export headers don't match what the automation expects.

Why Depop and Wayfair exports don't line up

Depop: a transaction date column; item price and Depop's payment processing fee as separate lines; a transaction ID rather than a traditional order number. Also, like Poshmark, the export is minimal and mixes sold, refunded, and offer-related rows together.
Wayfair: a purchase order date distinct from the ship date required by Wayfair's supplier terms; wholesale cost, freight allowance, and Wayfair's referral fee as separate columns; a Purchase Order (PO) number rather than a typical order ID. Also, built for suppliers rather than direct-to-consumer sellers, so column names lean toward logistics (PO, ship window) rather than retail checkout fields.

For spreadsheet automation, that mismatch is exactly what causes hours of manual cleanup every period.

Open CSV Experts and set your target columns once (Date, Channel, Order ID, Total).
Drop in your Depop export and map its columns once.
Drop in your Wayfair export and map it the same way — both merge into one sheet, normalized.
Export as CSV or Excel. Same-layout files merge automatically next time.

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

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