Scope and limitations

Strict JSON preserves numeric tokens, key order and string escapes. JSON5 uses JavaScript number semantics. Formatting is limited to 200 nesting levels; large content is paged but processed in full.

Common mistakes

Strict mode rejects single quotes, comments and trailing commas. Editing one segment does not delete the other segments.
