Formateador JSON

JSON (JavaScript Object Notation) has become the universal language of data exchange across the web — used in REST APIs, configuration files, databases and almost every modern software system. But raw, minified JSON is virtually unreadable to the human eye, and even a single misplaced comma or unclosed bracket will cause a complete parse failure. Our JSON formatter and validator instantly beautifies any JSON string into properly indented, colour-highlighted output, while simultaneously validating its syntax and pointing to the exact location of any error.

JSON formatting is a cornerstone of modern developer workflows. If you work with encoded data, our Base64 Encoder/Decoder pairs perfectly with JSON work — many APIs transmit binary or sensitive JSON data in Base64 encoding, and being able to decode it instantly is an essential debugging skill for any backend or full-stack developer.

For time-sensitive API responses and database records, our Unix Timestamp Converter translates the epoch timestamps that appear in virtually every JSON API response into human-readable dates — an indispensable tool when debugging date-related logic in any modern application.

¿Qué es JSON y por qué está en todas partes?

JSON fue propuesto por Douglas Crockford en 2001. En 2010 había reemplazado en gran medida a XML para las API REST. Google Maps, Stripe, GitHub — todos usan JSON. Su poder radica en su simplicidad.

Por qué los errores de sintaxis JSON son tan costosos en producción

JSON tiene tolerancia cero a errores: una coma mal colocada provoca un fallo total de análisis. Nuestro validador indica la línea y columna exactas de cada error.
