JSON Formatter CLI

The tool provides a CLI-style JSON formatter designed for developers, data engineers, and IT operations staff who regularly exchange JSON payloads, logs, and configuration data. It accepts raw JSON text and returns consistently formatted output, enabling easier review, diffs, and automated processing without embedding formatting logic in client code.
Conceptual workflow: parse input into a hierarchical object model, then emit text with uniform indentation and line breaks. Optional key sorting yields deterministic diffs across commits or environments. Indentation width is configurable (0–8 spaces) and output can be compacted by choosing a zero indent. The formatter adheres to RFC 8259 and reports precise parsing errors.
Users include API teams preparing payloads, data engineers validating logs, and QA automation pipelines that require consistent JSON for tests and diffs. Typical tasks encompass transforming messy payloads, normalizing API responses, and making configuration files human-friendly while preserving machine readability.
Unique value lies in its lightweight, backend-focused approach that does not require a browser or external dependencies. It delivers fast formatting, stable key order when requested, and clear error messages to speed debugging. It also exposes a clean, API-friendly interface suitable for embedding into scripts and CI workflows.
Core features and use cases: parse and validate JSON, pretty-print with adjustable indentation, optional sort_keys, and output both formatted and minified variants. It handles errors gracefully and can be wired into pipelines for automated formatting, diff generation, and repository hygiene. Advanced usage includes streaming large inputs in chunks and integrating via stdout redirection into CI pipelines.
