Cases when JSON does not work

1. Invalid JSON Syntax: JSON requires strict adherence to its syntax rules. If the JSON data contains any syntax errors, it will fail to work. For example, missing or extra quotation marks, incorrect placement of commas or colons, or forgetting to enclose the keys and values in double quotes.
2. Large JSON Data: JSON can become inefficient when dealing with large datasets. As the size of the JSON data increases, the parsing and processing time also increase. This can lead to performance issues and slower response times, especially in resource-constrained environments.
3. Circular References: JSON does not support circular references, where an object refers to itself or refers to another object that eventually points back to the original object. When parsing such JSON data, it may result in infinite loops or unexpected behavior.
4. Lack of Schema Validation: JSON does not have built-in support for schema validation. It means that JSON data may not always adhere to a predefined structure or set of rules. This can lead to compatibility issues and difficulties in ensuring data integrity and consistency.
5. Security Concerns: JSON data can potentially be vulnerable to security risks such as JSON injection attacks. These attacks occur when untrusted data is injected into the JSON structure, leading to unintended consequences such as code execution or unauthorized access to sensitive information.
6. Limited Data Types: JSON has a limited set of data types compared to other formats like XML or Protobuf. It supports basic types such as strings, numbers, booleans, arrays, and objects. However, more complex data types like dates, binary data, or custom types require additional handling and may not be handled efficiently by JSON.
7. Performance Overhead: While JSON is a widely used and supported format, it may not always be the most performant option for all use cases. Parsing and serializing JSON can require significant computational resources, especially in resource-constrained environments or when dealing with high-frequency data updates.

What are top JSON instruments and tools?
