JSON Formatter

The JSON Formatter converts raw JSON text into a readable, consistently indented form and validates syntax to ensure correctness. It accepts a single input string and optional formatting controls to produce either a pretty-printed or minified result. The tool is designed for developers, data engineers, and API testers who frequently inspect API responses, configuration files, and log data. Conceptually, it parses the input into a formal data structure, serializes that structure back to a string with user-specified options, and surfaces explicit errors when the input is invalid. The formatter emphasizes correctness, speed, and predictable output across large payloads, making it easier to spot structural issues and to compare changes over time. Unique value lies in its deterministic formatting, explicit error localization, and straightforward options for indent size and key sorting. Use cases include API debugging, configuration review, and data pipeline validation, where readable JSON accelerates comprehension and reduces debugging cycles. It differentiates itself by offering clear error details (line and column), fast processing for large JSON documents, and optional key sorting to aid diff comparisons, all without requiring any external dependencies.
