How can I validate a JSON file?

You can validate a JSON file using online validators or programming libraries. Do you have a specific method in mind?

I prefer using a programming library. Which one do you recommend?

For JavaScript, you can use 'ajv' or 'joi'. For Python, 'jsonschema' is a great choice. Would you like code examples?

Yes, please provide an example using Python.

Sure! Here's a simple example using 'jsonschema':

import json
from jsonschema import validate, ValidationError

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

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

# Validate
try:
    validate(instance=data, schema=schema)
    print("JSON is valid!")
except ValidationError as e:
    print(f"JSON is invalid: {e.message}")
