Tests each input for membership in a list and emits one boolean per input. Sibling of Equals (compares against a single value) and Match (regex). Reach for In List when you have a fixed set of allowed values — e.g. checking an employee’s email against a list of addresses, which is far easier to read than an alternation regex.

​
Inputs

  • In — the stream of dated properties to test.
  • List — the values to check membership against. Wire a Constant node with Is list enabled.

​
Outputs

  • Result — one boolean per input: true when the value is a member of the list.

​
Tips

  • String values and list members are trimmed before comparison, so stray whitespace in source data won’t cause a miss.
  • Comparison is case-sensitive. To match regardless of case, normalise case on both sides upstream.
  • Wire the result into Switch’s check port to branch on the membership test.
