The Best Way to Merge Amazon Seller Central and Facebook Marketplace 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 Amazon Seller Central file first. The first time you see this file shape, you map each of its columns to your target list.
  3. Import the Facebook Marketplace 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

Amazon Seller Central gives you a purchase date/time column stamped in UTC, not your local time, while Facebook Marketplace gives you an order date recorded through Meta's commerce backend — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, Amazon Seller Central's export reports differ noticeably between the 'All Orders' report and the Payments/Settlement report — totals rarely match at a glance, and Facebook Marketplace's many sellers use Marketplace only for listings with no built-in checkout, so exports may only exist via a connected store's own platform. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for google sheets import actually come from.
