JSON, YAML and TOML converter

Convert in both directions with explicit type and precision checks.

How it works and limits

Single document, 100,000 characters, 10,000 values and 40 levels. YAML aliases/custom tags/duplicate keys are rejected. JSON unsafe integers and nonfinite numbers are rejected; quote large identifiers. TOML requires a table root and has no null; dates convert to ISO text. Comments and original formatting are lost. Never paste credentials or private configuration.
