How to use JSON Canonicalization Workbench

Serialize a bounded JSON document with UTF-16 property ordering and ECMAScript number spelling. Canonical source and an optional digest identify the exact UTF-8 output.

  1. Enter input.
  2. Choose the settings for json canonicalization workbench, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 100,000 characters,10,000 values and40 levels. Duplicate decoded member names, unpaired surrogates, nonfinite numbers and nonzero numeric underflow are refused.
  • Numbers follow IEEE754 parsing and ECMAScript serialization; decimal precision beyond that model is not retained. This is canonical serialization, not encryption or signature verification.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Is sorting the keys of a normal object enough?

No. Integer-like keys can be enumerated differently, so this serializer emits sorted member text directly and checks the input domain.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
