✅ Solution & explanation
$input.all().map(item => item.json.email)
Output: ["[email protected]", "[email protected]"]
$input.all() returns every item that reached the node. Each item stores its data under .json, so the mapper reads item.json.email.💡 Pro tip: In Run Once for Each Item mode use $input.item.json instead.
