How can I validate JSON data in my application?

You can validate JSON data using libraries like Ajv for JavaScript or jsonschema for Python. Would you like examples?

Yes, please provide an example using Python.

Sure! You can use the jsonschema library. First, install it using pip install jsonschema. Then, you can validate like this:

import jsonschema
from jsonschema import validate

# Define your schema
schema = {
    "type": "object",
    "properties": {
        "name": {"type": "string"},
        "age": {"type": "integer"}
    },
}

# Example JSON data
data = {"name": "John", "age": 30}

# Validate
validate(instance=data, schema=schema)

What happens if the data doesn't match the schema?

If the data doesn't match the schema, a jsonschema.exceptions.ValidationError will be raised, indicating what went wrong.
