Pass it a schema validation of the types (rather than inferring from the values). And it will raise an error if the format of your data is bad.

e.g.

from jsonschema import validate

schema = {
    "type" : "object",
    "properties" : {
        "name" : {"type" : "string"},
        "price" : {"type" : "number"},
    },
}

# If no exception is raised by validate(), the instance is valid.
validate(instance={"name" : "Eggs", "price" : 34.99}, schema=schema)

# This will raise an error because of the bad type.
validate(
    instance={"name" : "Eggs", "price" : "Invalid"}, schema=schema,
)
