What does the Order Data Merger do?

It takes order export CSVs from multiple sales channels, normalizes the data into a unified format, and deduplicates entries based on your chosen criteria (email, phone, address, or order ID). The result is a single clean CSV with all your orders.

Which sales channels are supported?

The tool supports order exports from Shopify, Amazon Seller Central, eBay, WooCommerce, Etsy, and generic CSV formats. It auto-detects the source based on column headers.

Is my order data kept private?

Yes. All merging and deduplication happens entirely in your browser. Your order data, customer emails, addresses, and other sensitive information are never uploaded to any server.

How does deduplication work?

You choose a deduplication key: email address, phone number, shipping address, or order ID. The tool normalizes the chosen field (lowercasing emails, formatting phone numbers, standardizing addresses) and groups matching records together, keeping the most complete version.

How many orders can I merge at once?

The tool handles up to 100,000 combined order rows across all uploaded files. For very large datasets, the merge process runs in batches to keep your browser responsive.
