jsonEndObject

Closes an object within a JSON array. Takes json string, appends "}", returns result via ReturnString.

This function completes object element syntax inside array. Appends closing brace to match jsonBeginObject opening. Must be called after adding all object fields. Completes valid JSON object syntax within array. Use as final step for each array object. Common pattern: jsonBeginObject, add fields, jsonEndObject. Brace matching is critical - every begin must have matching end.
