About LRC-JSON Converter

Our LRC-JSON converter is a powerful, free online tool that enables seamless conversion between LRC (Lyric) format and JSON (JavaScript Object Notation). LRC is widely used in music players and karaoke apps to synchronize lyrics with audio playback. JSON is a structured data format ideal for developers and apps requiring programmable access to lyric data.

What is JSON Format?

JSON (JavaScript Object Notation) is a lightweight, language-independent data format that's easy for both humans and machines to read. In the context of lyrics, it allows for structured representation of time-aligned lyric data, making it suitable for APIs, mobile apps, music analytics, and real-time rendering in modern applications.

How to Convert LRC to JSON

  1. Select your conversion direction (LRC to JSON or JSON to LRC)
  2. Upload your file or paste its content directly into the input box
  3. Click "Convert" to process the lyric data
  4. Download the result or copy the structured output
  5. Integrate the JSON into your app or backend system
