From MessagePack

Converts MessagePack encoded data to JSON. MessagePack is a computer data interchange format. It is a binary form for representing simple data structures like arrays and associative arrays. From MessagePack lives in the Data format category of the fx menu. See MessagePack for format details.

Parameter

Input	string	yes	—	Value to transform. Previous step output or a literal.

Input is the primary value (previous step output or a literal).

Returned value

JSON	Result of the From MessagePack transformation.

Limitations

• This operation treats Input as raw bytes (binary-capable). Non-text payloads may display differently after decoding.
• Invalid or mismatched encoding for the chosen options typically raises an evaluation error — fix the Input or options before re-running.
