Iterator
also loop
A module that splits an array into separate items so each one is processed individually by the following steps.
Analogy
Like opening a box of letters and handling each one separately rather than all at once.
Why it matters
Iterators let you process lists, such as multiple line items or contacts, one at a time in Make-style automations.
In practice
A Make iterator splits an array of order line items so each item gets its own row in a sheet.
