Visual detection method and device for serialized data, terminal and medium

The invention relates to a visual detection method and device for serialized data, a terminal and a medium. The method comprises the following steps: pre-loading a serialized data structure of a serialized data application and a deserialization method; performing deserialization analysis processing on the serialized data by using the deserialization method, and determining each serialized data structure and/or a data region which cannot be deserialized in the serialized data; representing different serialized data structures and members in the serialized data structures by using block diagrams with different colors, and representing the data region which cannot be deserialized by using a fault icon; and according to the sequence of each serialized data structure and/or the data region which cannot be deserialized in the serialized data, correspondingly combining each block diagram and/or the fault icon to form a visual sequence diagram. According to the method, serialized data composition and design defects c
