The Best Way to Merge Etsy and eBay Data for Year-End Sales Summary
If you're doing year-end sales summary 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
- 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.
- Import the Etsy file first. The first time you see this file shape, you map each of its columns to your target list.
- Import the eBay file the same way. Its columns get mapped once too — after that, every future file with this shape merges with no extra clicks.
- 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.
- Export. CSV or Excel, ready for year-end sales summary.
What actually goes wrong if you do this by hand
Etsy gives you Sale Date, usually already in your local timezone, while eBay gives you Sale Date shown in the seller's local time — line those up manually across a few hundred rows and it's easy to miscount a week. On top of that, Etsy's export listing titles are included in full and often contain commas, which can shift columns if opened carelessly in Excel, and eBay's the seller hub export format changed more than once, so column names can differ depending on when the report was generated. Individually those are minor quirks; combined into one spreadsheet by hand, they're where most reconciliation errors for year-end sales summary actually come from.
Why it matters for year-end sales summary
A year-end summary across channels means twelve months of exports from each platform, all needing the same cleanup before they can be totalled together.
