JSON to TOML Converter

This data format converter transforms JSON (JavaScript Object Notation) input into TOML (Tom's Obvious Minimal Language) output using a recursive descent serialization algorithm. The converter processes the JSON abstract syntax tree, mapping each node type to its TOML equivalent: string values receive quoted encoding with proper escape handling, numeric types preserve integer and float distinction, and boolean literals translate directly.

Nested JSON objects convert to TOML table sections using bracket notation ([section.subsection]), creating the hierarchical structure that makes TOML configuration files human-readable. Arrays of primitive values serialize as inline arrays maintaining comma-delimited formatting, while arrays of objects generate TOML array-of-tables syntax using double brackets ([[array.item]]) per the TOML v1.0 specification. The converter handles edge cases including keys containing special characters (quoted key format), multiline string detection (triple-quote encoding), and null value omission since TOML lacks a null type.

Real-time conversion triggers on every keystroke using React's useEffect hook, providing instant feedback as users type or paste JSON content. The dual-pane interface features syntax-highlighted editors powered by Prism.js with language-specific tokenization for both JSON input and TOML output. File upload accepts .json and .txt formats, while the download feature exports results as properly formatted .toml configuration files.
