Make SKUs for your products

Give a product and its options, such as colours and sizes, to get a consistent SKU for every combination: readable codes like EP-CM-BLC-SML, with your own codes where you want them and an optional running number. Download the list as a CSV for Shopify, Etsy or your stock sheet.

Your product

Codes are made from each value (Black → BLC, Navy Blue → NB). To choose one yourself, write it after an equals sign: Sea Green=SG.

SKUs

    The CSV opens in Excel, Google Sheets and Numbers, ready to paste into Shopify, Etsy or your stock list. Keep each SKU unique and never reuse an old one for a different product.

    Runs in your browser. Nothing you type is sent anywhere.

    How it works

    1. Your prefix, a code for the product and a code for each option value are joined with the separator you choose.
    2. Codes are initials for several words (Navy Blue → NB), otherwise the first letter and the consonants (Black → BLC). Write “Value=CODE” to set one yourself.
    3. Every combination of options gets its own SKU; values that would clash get a number, and the whole list downloads as a CSV.

    What it makes

    You enter
    A product name and its options that you type
    You get
    A CSV with every SKU and its options, or the SKUs copied as a list
    Limits
    Every combination of options is listed; the screen shows the first 200, the CSV has them all.
    • Codes are made from letters and numbers only, so they’re safe in every system and spreadsheet.

    What you enter stays on your device

    This tool runs entirely in your browser. Nothing you type is sent to our servers, so there is nothing for us to store, see or delete.

    To check, open your browser’s developer tools, switch to the Network tab and use the tool: you will not see what you type being sent anywhere.

    Questions

    What makes a good SKU?

    Short, unique and readable: letters and numbers only, the same order of parts every time, and no meaning that will change (such as a price). Never reuse an old SKU for a different product.

    What’s the difference between a SKU and a barcode?

    A SKU is your own code for your own stock. A retail barcode (EAN or UPC) is a number licensed from GS1 that identifies the product everywhere. You can print a SKU as a Code 128 barcode with the barcode generator.

    Is what I enter saved or sent anywhere?

    No. Everything runs in your browser and nothing you type is sent to our servers.
