Patterns, not typing
Write TSH-{COLOR}-{SIZE} and get TSH-BLACK-S, TSH-BLACK-M and all the rest. Click an option name to insert its token.
SKU generator
SKU generator: one pattern, every variant.
Write a pattern once. VariantFlow fills in each variant’s own values and gives you clean, unique SKUs — and tells you if two ever collide.
Clean by default
SKUs are uppercased, spaces become hyphens and unsupported characters are removed, so every SKU imports cleanly.
Duplicates caught early
If two variants end up with the same SKU, or one is missing, VariantFlow flags the row before you export.
How it works
From idea to import in three steps
- 1
Add your options
Size, Color, Material — whatever defines your variants.
- 2
Write the pattern
Mix fixed text with option names in curly braces.
- 3
Review and adjust
Edit any SKU by hand. Edited fields are highlighted and can be reset.
FAQ
Frequently asked questions
What makes a good SKU?
Short, consistent and readable: a product code followed by the option values in the same order every time, separated by hyphens.
Which characters can a SKU contain?
VariantFlow keeps letters, numbers, hyphens and underscores, which import reliably on every platform.
Can I change one SKU without changing the pattern?
Yes. Type over any SKU in the table. It stays as you set it until you reset it.
