What this guide covers

Use this JSON Split Tool to break JSON into smaller parts for review and reuse. It is especially useful for splitting top-level arrays into separate items or top-level object keys into separate blocks, which helps with debugging, exporting, test preparation, and working with large JSON structures more comfortably.
