JSON Formatter Extension

The JSON Formatter Extension is a domain-focused transformer that converts raw JSON text into a readable, standardized form. It supports pretty printing, minification, and compact representations for log-friendly outputs. The tool validates syntax against RFC 8259 and emits clear error details when parsing fails. It is designed for developers, QA engineers, data engineers, and API teams who need consistent JSON for debugging, documentation, and data sharing. The extension differentiates itself with deterministic serialization, optional key sorting, and configurable indentation that users can tailor to their project style. By encapsulating the transformation logic in a lightweight, dependency-free module, it enables rapid, repeatable formatting across environments. Use cases include preparing API payloads for demos, auditing responses in logs, and aligning JSON samples in technical reports. The core value lies in reducing cognitive load during data inspection and speeding up collaboration through readable, predictable outputs. This tool focuses on the transformation itself, avoiding schema interpretation or code execution, and it supports large payloads through efficient parsing and streaming where possible.
