Deterministic conversion
How this encoding works
JSON is parsed first, serialized in the selected layout, encoded as UTF-8 bytes and then converted to standard Base64.
Honest limitations
Encoding does not add secrecy or missing types
Base64 is an encoding, not encryption. Anyone with the encoded text can decode its contents.
