JSON Formatter

This tool formats a given JSON string, delivering a deterministic, readable representation suitable for development, testing, and API validation workflows in Angular environments. It targets developers, QA engineers, and DevOps practitioners who routinely exchange payloads across services and repositories. By ensuring consistent formatting, it reduces diffs and simplifies code reviews.
Core logic includes strict parsing with syntax validation, followed by serialization into either a pretty-printed block or a compact single-line string. Required features: JSON.parse-safe processing, accurate error reporting, and consistent output formatting. Advanced options: indentation size (spaces or tabs), minification, and optional key sorting. It preserves data structure and types while presenting them clearly; no schema interpretation is performed.
Inputs are the raw JSON string and optional formatting controls; outputs are the formatted string and a status payload (success or error) with optional error position. Example: input '{"a":1,"b":[1,2,3]}' with indent=2 yields a multi-line, human-friendly representation. Use cases include preparing test fixtures, validating API payloads, and ensuring lintable JSON in CI pipelines. The tool is designed for developers who value speed, predictability, and ease of integration with Angular tooling, build scripts, and quality assurance workflows.
