JSON to TOML Converter

About this calculator

TOML (Tom's Obvious Minimal Language) is a configuration-file format designed to be trivially readable, and it is the standard format behind Rust's Cargo.toml package manifests, Python's pyproject.toml build configuration, and many other developer tool config files. Converting a JSON object to TOML means re-expressing the same data with TOML's own conventions: string values are quoted, numbers and booleans are written bare, nested objects become [table] sections, and arrays stay in bracketed list form.

This tool performs that structural translation for simple JSON objects automatically, which is useful when migrating a config from a JSON-based tool to a TOML-based one, or when hand-writing TOML from a JSON example without memorizing the syntax differences.
