Frequently Asked Questions

Which TOML files does this converter support? ▾

Any valid TOML v1.0 — Cargo.toml for Rust, pyproject.toml for Python, Netlify and Hugo configs. Tables, arrays of tables, dates, and multiline strings all convert to their JSON equivalents.

How are TOML dates converted to JSON? ▾

TOML has native date-time types; JSON does not. They serialize as ISO-8601 strings (2026-01-15T10:30:00Z), which every JSON parser round-trips safely.

Why convert pyproject.toml to JSON at all? ▾

Tooling: JSON is what most scripting environments consume natively. Converting lets you inspect resolved dependency trees or feed configuration into Node-based pipelines without a TOML parser.
