What is a JSON Validator?
A JSON Validator checks whether your JSON data follows the correct JSON syntax and structure.
Why Validate JSON?
Invalid JSON can cause errors in APIs, websites, applications, configuration files and databases. Validation helps identify syntax problems before using the data.
Common JSON Errors
Common problems include missing commas, incorrect quotation marks, missing brackets, extra characters and improperly formatted values.
Is my JSON uploaded?
No. Validation happens directly inside your browser. Your JSON is not sent to the HoxTools server.
