Developer toolHow to choose your tool
Inspect a JSON payload, decode Base64, generate identifiers, or translate an epoch timestamp. These utilities are useful for debugging, test fixtures, and documentation. Base64 is an encoding rather than encryption. JSON validation checks syntax rather than a schema. Keep these distinctions in mind when working with production data.
