List every combination from two or more sets, such as sizes × colors. Enter one comma-separated set per line.

This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

The calculator pairs every item with every item in the other lists. Multiply list sizes to find the result count.

The result contains comma-separated tuples in parentheses. The rightmost list changes fastest.

  • List every size, color, and material variant of a product before you create SKUs.

Combine two lists across an empty line

Input: {a,b} {1,2}

Settings: One set per line; comma-separated members.

Result: (a, 1) (a, 2) (b, 1) (b, 2)

The first list supplies a or b; the second supplies 1 or 2.

Separate sets and interpret tuple order

  1. Separate items with Item delimiter.
  2. Separate lists with Sample delimiter. The default requires a blank line.
  3. Run the calculation after checking every list boundary.
  • Repeated items produce repeated tuples.
  • Spaces remain part of an item.
  • The parser does not interpret CSV quoting.
