Merge Amazon Seller Central and Wix Sales Data for Tax Prep in New Zealand

At tax time you need total revenue by channel without hand-fixing each export's columns first. In New Zealand, that also means accounting for GST: GST is a flat 15% once you're registered, with no state/province split needed since it's a single national rate.

Why Amazon Seller Central and Wix exports don't line up

Amazon Seller Central: a purchase date/time column stamped in UTC, not your local time; item price, promotion discounts, and Amazon referral fees split across several columns; an Amazon Order ID in a long dashed format (e.g. 123-4567890-1234567).
Wix: a Date Created column; a Total column with tax handling that varies by store region; an Order # formatted as a short number.

Neither export is built with GST in mind, so getting from "two raw files" to "New Zealand-ready numbers" means normalizing dates/totals first, then applying your own GST treatment on top of the merged total — not per platform separately.

How to merge them

Set your target columns once in CSV Experts (Date, Channel, Order ID, Total, and a Currency column if you sell in more than NZD).
Map the Amazon Seller Central export, then the Wix export — each file shape is remembered after the first time.
Export the merged sheet and apply your GST treatment to the combined total.

FAQ

Does this upload my sales data anywhere?

No. Everything runs in your browser using JavaScript — your files are never sent to a server.

Does it work for more than two channels?

Yes. Add as many source files as you want; each distinct file layout is mapped once and remembered.
