📄 TOML ↔ JSON Converter
Convert between TOML and JSON with a hand-rolled parser/serializer for a solid, common TOML subset. Nothing leaves your browser.
Supports key/value pairs (including dotted keys like
a.b = 1), [section] and
[section.sub] tables, basic double-quoted and literal single-quoted strings, integers
(incl. 0x/0o/0b and _ digit separators), floats,
booleans, and single-line arrays (including nested arrays). It deliberately rejects
multi-line """/''' strings, inline tables { }, array-of-tables
[[section]], and dates/times with a clear error, rather than silently mishandling them.
JSON → TOML likewise rejects null and arrays of objects (both need syntax this converter
doesn't generate).
