8 Best Free Online JSON Schema Generator Websites

Here is a list of best free online JSON schema generator websites. JSON or JavaScript Object Notation is a text-based structured document to represent JavaScript Scalar Data, Arrays, and Object Literals. On the other hand, JSON Schema is a format that carries validated and annotated JSON data. In various applications, it is required to have a properly validated JSON schema. To generate properly validated and annotated JSON schema, users need these JSON schema generator websites.

These websites use the standard JSON data to create or generate a valid JSON schema. Some websites also let users adjust the output JSON schema parameters before starting the generation process. Plus, tools to edit the final JSON schema data is also present on some of these websites. A few websites also detect and show whether the input JSON document data is valid or not. I also like the ability of some of these websites to fetch JSON document files from online sources using URLs. The process to generate JSON schema is quite simple. Still, to help out new users, I have included the necessary JSON schema generation steps in the description of each website. After generating the schema, users can copy or save the data locally in the form of a TXT file.

These websites also come with additional JSON, XML, and Code Beautification Tools. Go through the list to know more about these websites.
