Parse TLV

Converts a Type-Length-Value (TLV) encoded string into a JSON object. Can optionally include a Key / Type entry. Parse TLV lives in the Data format category of the fx menu.

Parameters

Parameter	Type	Required	Default	Description
Input	string	yes	—	Value to transform. Previous step output or a literal.
Type/Key size	number	no	1	Numeric value. Default 1.
Length size	number	no	1	Numeric value. Default 1.
Use BER	boolean	no	false	Disabled by default.

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

Returned value

Type	Description
JSON	Result of the Parse TLV 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.

Example

Run Parse TLV

Converts a Type-Length-Value (TLV) encoded string into a JSON object. Adjust optional parameters when the defaults do not match your payload.

1. Set Input to the value to transform (previous step output or a literal).

2. Review Type/Key size, Length size, Use BER and keep defaults unless your format requires otherwise.

3. Confirm Output value shows the transformed result.
