JSON aware when needed

You can enforce real JSON validation before encoding or after decoding, or turn it off when you only need raw UTF-8 text transport.

Good for transport fields

Base64 is handy when JSON must pass through one-line text fields, fixtures, or encoded payload slots.

Round trip locally

Everything runs in the browser, including UTF-8 conversion, Base64 handling, and optional JSON checks.
