The Best Way to Merge Bonanza and Wayfair 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
- 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 Bonanza file first. The first time you see this file shape, you map each of its columns to your target list.
- 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.
- 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 spreadsheet automation.
What actually goes wrong if you do this by hand
Bonanza gives you a sale date shown in the seller's account timezone, 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, Bonanza's export fee amounts differ per listing based on optional ad placement, so two otherwise-identical sales can show different fee columns, 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 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.
