A SKU generator creates stock keeping unit codes for a product list from attributes like category, brand, colour and size. It is built for small sellers and shop owners who need a consistent naming rule across a catalog instead of making up each code by hand as new products are added.
Enter your Product List and Attributes, listing each product with the details such as category, brand, colour or size that should appear in the code.
Pick a SKU Code Philosophy such as Descriptive or Sequential, set the SKU Parts in Order and choose a Segment Delimiter like a hyphen or underscore.
Select Generate SKUs. You get a table of each product with its SKU and the naming rule used, so you can apply the same pattern to future products.
When you are setting up a store for the first time, deciding the SKU pattern early, before you have hundreds of listings, saves you from renaming products later to fix an inconsistent system.
Items that come in several colours and sizes need codes that encode both, so a shopper's order and your warehouse pick list refer to the exact same variant without confusion.
A written naming rule, not just the codes themselves, lets a co-founder, employee or warehouse partner generate correct new SKUs themselves instead of asking you to build every new product code.
It produces a SKU code for each product you list, built from the attributes and code pattern you choose, plus a written naming rule explaining how each part of the code was formed and ordered.
You can try it without an account, though free use has a daily limit. It only uses the product list and attributes you type in and cannot pull data from your store or spreadsheet directly on its own.
The tool applies the rule and collision handling option you pick, but you should still check the output against your existing catalog before uploading it, since it cannot see your current live SKU list at all.
A good SKU is short, consistent and readable by a person, usually combining category, key attributes like colour or size, and sometimes a sequence number, separated by a hyphen or underscore character for added clarity.
Most retail guides advise against putting price in a SKU, since prices change often and the code should describe the product itself, not a detail about it that will eventually go out of date and confuse staff.
A SKU is an internal code you define yourself for tracking stock, while a barcode such as a UPC is typically a standardized number assigned externally for retail scanning and resale purposes at the checkout counter.
Build a formula to look up your new SKU codes once you export the table.
Useful for a new shop setting up its SKU system that also needs a short purpose statement written.
Helpful for shortening long category or attribute names into the clean short codes a SKU pattern needs.
Useful if you are naming an internal product line or project before assigning SKU codes to its items.
Choose the primary strategy for constructing your SKUs.
Define the structure using attribute placeholders (e.g., {BRAND}-{COLOR}-{SIZE}-{COUNTER}). Use {COUNTER} for uniqueness.
