SKU Generator is a free tool offered as-is. It turns the prefix, axes, separator, and case you enter into variant SKU strings and a CSV. It may be unavailable, change, or produce a matrix that does not fit a channel’s latest import file.
You are responsible for the codes you export. That includes uniqueness in your catalog, conflicts with SKUs you already sell, trademark issues if a code contains a brand, and the rules of each marketplace or store you use. The site does not reserve SKUs globally.
Download CSV writes SKU, the product, one column per attribute, and Options. The page marks duplicates in the batch. Stock, barcodes, and warehouse records stay in the store or ERP you already use.
To the extent the law allows, the operator is not liable for rejected imports, duplicate codes, or lost sales that follow from how you use the output.
