# TOML formatter, validator, converter

Check TOML with positioned errors, reformat it, or walk it to and from JSON through the shared interchange model: dates keep their TOML shapes, integers stay exact past 2^53, nulls drop with a count, every loss in the report.
ValidateFormatTOML → JSONJSON → TOMLCopyDownloadPaste, drop, or type to begin. Everything stays on this device.
