About the formats
JSON
JavaScript Object Notation
JSON is the lightweight text format web services and apps use to exchange data. It nests objects, arrays, numbers and strings.
TOML
Tom's Obvious, Minimal Language
TOML is a format designed for configuration files: it looks like INI but defines types precisely. Rust (Cargo) and Python (pyproject) projects use it.
Frequently asked questions
Is converting JSON to TOML free?
Yes, completely free. No account, no daily limit, no watermark and no queue.
Does it work on a phone?
Yes. It works on iPhone, iPad and Android, with no app to install.
Is there a file size limit?
There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
