jsonify

jsonify is a lightweight, cross-platform C++17 command-line utility designed to parse, format, lint, and automatically repair JSON and JSONC (JSON with comments) files.

Built with strict performance and minimal dependencies in mind, jsonify provides a full developer pipeline for inspecting and cleaning up JSON data.

Features

• Robust Parsing: Validates and transforms raw JSON strings into an efficient, traversable node tree.
• Advanced Linting: Catches structural warnings, empty keys, deeply nested objects (>20 levels), duplicate object keys, and mixed data types within arrays.
• Pretty-Printing & Formatting: Custom terminal formatting featuring syntax-highlighting (colorized keys, strings, and numbers) or compact minification.
• Auto-Correction (--fix): Automatically cleans up loose or trailing commas safely outside of string literals.
• JSONC Support: Cleanly strips single-line (//) and multi-line (/* */) comments before parsing.
