adofai-json-parser

A lightweight, pure Kotlin ADOFAI level JSON parsing library with an API similar to JavaScript's JSON.parse() and JSON.stringify().

Project URL: https://github.com/adofaiex/adofai-json-parser

Features

• ✅ Pure Kotlin implementation, no external dependencies
• ✅ Multi-platform: JVM and Kotlin/Native (Windows, macOS, Linux)
• ✅ Simple API, similar to JS's JSON API
• ✅ Reviver / Replacer support (transform values during parsing / serialization)
• ✅ Pretty printing (formatted with indentation)
• ✅ Full JSON support (objects, arrays, strings, numbers, booleans, null)
• ✅ Lenient parsing: supports JSON with trailing commas and newline-containing strings
