How to Validate a JSON File in Python

There are a few built-in ways to validate JSON files in Python, but they aren’t always efficient or easy to implement. Using the free API solution below, you can easily validate your JSON text files in a single step with ready-to-run, copy & paste code examples. This API will identify if your JSON file is invalid, and if so, it’ll provide critical information regarding any errors found in the file and any warnings associated with those errors. It’ll also let you know if the file is password-protected, which is always super important to know.

Just run this command to install the Python SDK:

pip install cloudmersive-convert-api-client

Then copy in the imports and call the function:

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint

# Configure API key authorization: Apikey
configuration = cloudmersive_convert_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'



# create an instance of the API class
api_instance = cloudmersive_convert_api_client.ValidateDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))
input_file = '/path/to/inputfile' # file | Input file to perform the operation on.

try:
    # Validate a JSON file
    api_response = api_instance.validate_document_json_validation(input_file)
    pprint(api_response)
except ApiException as e:
    print("Exception when calling ValidateDocumentApi->validate_document_json_validation: %s\n" % e)

And you’re already done! Completing your API call requires a free-tier Cloudmersive API key, which you can get here by registering a free account (please note: this account provides a limit of 800 API calls per month, and once that limit is reached, your total resets the following month; no charges are incurred).
