The Best Way to Merge Amazon Seller Central and TikTok Shop Data for Spreadsheet Automation

If you're doing spreadsheet automation 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 TikTok Shop 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 spreadsheet automation.

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 TikTok Shop gives you an order creation time stamped in UTC — 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 TikTok Shop's refunded and partially-refunded orders stay in the export with a status column instead of being removed, so totals can overstate revenue if you don't filter by status. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for spreadsheet automation actually come from.

Why it matters for spreadsheet automation

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