Conversion policy protects exact values
JSON has no native TOML date-time, NaN, or infinity values. Large integers can also exceed JavaScript's exact numeric range, so unsupported values produce explicit diagnostics.

Convert TOML to strict JSON without hidden coercion
Translate TOML tables, arrays, and compatible scalars into strict JSON while exposing representation gaps instead of silently changing values.

What this tool does
Strict, bounded, local processing
TOML and JSON do not share an identical type system. Date-times, 64-bit integers, infinity, and NaN must remain visible at the conversion boundary.
Comments are not JSON data
TOML comments and table presentation do not appear in JSON. Keep the source when annotations matter to maintainers.
