Helpful context
Setup notes, privacy details, and examples when needed.
The fixer first attempts strict JSON, then applies a bounded heuristic repair pass before parsing JSON5-compatible syntax and serializing strict JSON. Repairs can change ambiguous input and discard comments or lexical style, so review the result; incomplete or structurally ambiguous data may still fail.
