What does the Marketplace CSV Converter do?

It takes a product CSV exported from one marketplace (such as Shopify or Amazon) and converts it into the format required by another marketplace. It auto-detects the source format, maps fields between platforms, and transforms values like category names and variant structures.

Which marketplace formats are supported?

The tool supports Shopify, Amazon Seller Central, eBay File Exchange, Walmart Marketplace, and Google Shopping product feed formats. It handles the unique column names, required fields, and value formats for each platform.

Is my product data kept private?

Yes. All CSV processing happens entirely in your browser using client-side JavaScript. Your product data is never uploaded to any server. Nothing leaves your device.

What is the file size or row limit?

The tool handles CSV files up to 10MB and approximately 50,000 rows. For very large catalogs, split your file into smaller batches and convert each one separately.

What if some fields cannot be automatically mapped?

After auto-detection, the tool shows you all mapped and unmapped fields. You can manually assign any unmapped source columns to target fields using the dropdown mapping interface before converting.
