Merge Wix and Walmart Marketplace Sales Data for Tax Prep in Ireland

At tax time you need total revenue by channel without hand-fixing each export's columns first. In Ireland, that also means accounting for VAT: VAT at the standard 23% rate applies once registered, with the same EU cross-border thresholds as other EU sellers.

Why Wix and Walmart Marketplace exports don't line up

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

How to merge them

  1. Set your target columns once in CSV Experts (Date, Channel, Order ID, Total, and a Currency column if you sell in more than EUR).
  2. Map the Wix export, then the Walmart Marketplace export — each file shape is remembered after the first time.
  3. Export the merged sheet and apply your VAT 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.
