About Base64 to JSON Converter

The Base64 to JSON converter transforms Base64-encoded JSON strings back into formatted JSON data. This tool decodes the Base64 input and parses it as JSON, allowing you to view and work with the structured data in its original format.

Base64 is a binary-to-text encoding scheme that represents binary data in a printable ASCII string format. JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. This converter bridges these formats by decoding Base64 data and presenting it as properly formatted JSON.

Common Uses:

  • Decoding API responses that include Base64-encoded JSON data
  • Extracting JSON data from Base64-encoded JWT tokens
  • Viewing configuration data stored in Base64 format
  • Debugging applications that use Base64 encoding for JSON transmission
  • Converting data from legacy systems that encode JSON in Base64
  • Examining JSON data embedded in Base64 strings from various sources
  • Preprocessing data for applications that require JSON input
