About this tool

This tool allows you to validate your JSON data against a JSON schema. It uses the [ajv](https://ajv.js.org/) library to perform the validation.

To use this tool, paste your JSON schema in the left editor and your JSON data in the right editor. The tool will automatically validate your JSON data against the schema and display any errors.
It will also display errors if your JSON schema is invalid.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format. It is easy to read and write and easy to parse and generate using code.
It is based on a subset of the JavaScript programming language.

JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of many languages like C, C++, C#, Java or JavaScript. These properties make JSON an ideal data-interchange language.

What is a JSON schema?

A JSON schema is a JSON document that defines the structure of your JSON data. It allows you to specify the type of each field, the required fields, and any constraints on the data.

The JSON schema format is defined by the JSON Schema standard.

JSON schemas are useful for validating JSON data, generating documentation, and providing a contract for APIs.
