Inspect structured data or encode text
Choose JSON Validator to diagnose a syntax error and JSON Formatter to read a document, explore its tree, or create a compact version. Formatting changes presentation; it does not validate an application's required fields or data types.
Use Base64 for representation
Base64 encoding represents UTF-8 text using a restricted alphabet. It is reversible and does not encrypt a password or token. The decoder expects text content rather than an image or arbitrary binary file.
