Base64 and JSON — A Quick Technical Overview
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. JSON, on the other hand, is a lightweight data-interchange format commonly used in web apps. When JSON is Base64-encoded, it's unreadable until decoded back. This converter bridges that gap by decoding and parsing the content in one step.
