The Best Way to Merge Facebook Marketplace and Wayfair Data for Google Sheets Import

If you're doing google sheets import by hand right now, here's the fastest path from "two exports" to "one usable sheet," and why the manual version keeps breaking.

Step by step

  1. Decide your target columns once. Most people settle on Date, Channel, Order ID, and Total — set that up in CSV Experts and you won't redo it.
  2. Import the Facebook Marketplace file first. The first time you see this file shape, you map each of its columns to your target list.
  3. Import the Wayfair file the same way. Its columns get mapped once too — after that, every future file with this shape merges with no extra clicks.
  4. Check the merged totals. Dates and numbers are normalized automatically, so a European "24,00" and a US "24.00" both land as the same value.
  5. Export. CSV or Excel, ready for google sheets import.

What actually goes wrong if you do this by hand

Facebook Marketplace gives you an order date recorded through Meta's commerce backend, while Wayfair gives you a purchase order date distinct from the ship date required by Wayfair's supplier terms — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, Facebook Marketplace's export many sellers use Marketplace only for listings with no built-in checkout, so exports may only exist via a connected store's own platform, and Wayfair's built for suppliers rather than direct-to-consumer sellers, so column names lean toward logistics (PO, ship window) rather than retail checkout fields. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for google sheets import actually come from.
