Handles common TOML v1.0 features: tables, arrays of tables ([[section]]), inline tables, strings, numbers, booleans, dates. Exotic edge cases (multi-line arrays split across lines with mixed comments) may not round-trip perfectly.

Comment ça marche

  1. 1
    Paste TOML or JSON

    Drop either format - Cargo.toml, pyproject.toml, wrangler.toml, or any config file.

  2. 2
    Pick a direction

    TOML → JSON or JSON → TOML. The parser handles tables, [[array-of-tables]], and inline tables.

  3. 3
    Copy the output

    One click sends the converted config to your clipboard.

Questions fréquentes

Which TOML version?

TOML v1.0. Common features are supported: tables, array-of-tables, inline tables, strings, numbers, booleans, dates.

Does it preserve comments?

No - TOML comments are stripped on parse, same as YAML → JSON. That's a spec limitation, not a tool one.

Why do I care about TOML?

It's the config format for Rust (Cargo.toml), Python packaging (pyproject.toml), Cloudflare Workers (wrangler.toml), and many other modern tools.
