invoice_number, issue_date, total_amount.Use snake_case so the name is safe to use as a JSON key or column header.Field type
Field type
Tells anyformat what kind of value to expect (text, date, number, etc.).The type improves consistency, validation, and output quality. See Field types for the full list.
Instructions
