Summary

Function: string llList2Json( string type, list values );

This function takes a list and returns a JSON string of that list as either a json object or json array.
Returns a string that is either values serialized as a JSON type, or if an error was encountered JSON_INVALID.

• string type
• list values

To convert a json formatted string into a list use llJson2List.

Specification

See Json_usage_in_LSL

  • If type is JSON_OBJECT the list must be a strided list of key, value pairs and a string representing a json object will be returned.
  • If type is JSON_ARRAY then a string representing a json array will be returned.
  • If type is any other string then JSON_INVALID will be returned.
Type Flags Value Unicode URL Encoded HTML Encoded Description
JSON_INVALID U+FDDO "%EF%B7%90"  Value returned when inputs are not well formed.
JSON_OBJECT U+FDD1 "%EF%B7%91" 
JSON_ARRAY U+FDD2 "%EF%B7%92" 

Caveats

  • Note that values items are interpreted as JSON, not LSL, types. For example, llJson2List(llList2Json(JSON_ARRAY, ["bacon", "true", "false", "null"])) returns the LSL list ["bacon", JSON_TRUE, JSON_FALSE, JSON_NULL], while llJson2List(llList2Json(JSON_ARRAY, ["\"bacon\"", "\"true\"", "\"false\"", "\"null\""])) returns the LSL list ["bacon", "true", "false", "null"]
