JSON Validator

Best JSON Validator

Our JSON Validator tool verifies that your JSON structure complies with the JavaScript Object Notation specifications. The tool can determine whether your JSON data is valid and will give you the desired results or not, in just a single click, while working with complex structured data.

All you need to know about this tool:

JSON stands for JavaScript Object Notation. It is an open-standard file format that employs human-readable text to store and transfer data objects made up of arrays and key-value pairs. Key-value pairs are separated by a colon, as in "key": "value". The best course of action when working with complex JSON data is to confirm that your data is accurate and giving you the desired results.

Although JSON is very simple to write and edit, but programming, in general, requires attention and this can become challenging as coders have to focus more on developing the logical structure. As a result, specific rules for writing JSON may sometimes be overlooked due to human error. But don't worry, we have got you covered. Our JSON Validator helps you comply your JSON structure with the JSON specifications. Any errors are pointed out in real-time, so they can be fixed instantly.

How to use our JSON Validator tool?

You can easily launch our JSON Validator tool directly from our home page under the Development Tools Section. We aim to make our user's experience as convenient as we can. JSON Validator, like the rest of our tools, is incredibly simple to use. You would be able to use this verification tool without much help even if you don't have a lot of technical experience. Our JSON validator is one of the easiest ways to verify your JSON data and helps you fix any errors that occur due to non-compliance with JSON rules.

Initially, you can get to know the tool by using the sample JSON for validation. It can be done as:

Using the Sample JSON:

Before getting into the step-by-step guide, let us make it easy for you by providing the sample JSON.

  1. Open our JSON Validator's web page. You'll see a box with line number '1' written, and along with that, you can see a pair of curly brackets{}. In that box, the input JSON data is to be entered.
  2. Beneath the box, there are three buttons with blue, green, and orange colors, titled 'Validate', 'Sample', and 'Reset' respectively.
  3. Click on the Sample button. It will fill the empty box with sample JSON data.
  4. Then click on the Validate button to verify the correctness of sample JSON data.
  5. You can edit the JSON as you need, and if any error arises, a cross (x) sign will appear alongside that particular line number.

Using your Actual JSON:

Follow up with the instructions provided to validate your JSON data using this tool:

  1. Copy the JSON data from the file where it has been saved.
  2. Go to our online tool and paste your JSON data in the box beneath the label 'JSON Validator'.
  3. Beneath the box, there are three buttons with blue, green, and orange colors, titled 'Validate', 'Sample', and 'Reset' respectively. Click on the Validate button to start verification.
  4. In a matter of milliseconds, the result will appear in a new bar above the code.
  5. If the bar is green, and it says 'JSON is valid!', then you should feel relieved that your JSON data is compliant with the standard JSON rules.
  6. If the bar is red, and it says 'JSON is not valid!', it means that JSON data is not compliant with the JSON specifications. Cross (x) signs will appear alongside those particular line numbers, where there are errors.
  7. If you hover your mouse over any error sign, a description of the error will appear. It can be helpful for you to identify and fix the issues instantly.
  8. You can edit the entered JSON for fixing the errors, and the cross (x) signs will disappear in real-time, as soon as the error is removed.
  9. You can copy the fixed JSON, and save it in your project files.
  10. If you wish to change the JSON and want to validate some other data, you can do so by clicking firstly on the Reset button, it will clear all the fields. Then you can repeat the same procedure.

What can JSON Validation help you achieve?

A developer can work with JSON to do organized data transmission through a network connection. He may not have the time to make the JSON data fully comply with standard specifications, because one has to concentrate more on developing the JSON constructs such as objects, arrays, and members. This can create ambiguities regarding whether the JSON data is valid or not. Or it may contain issues that need to be fixed.

You can solve these problems by using our JSON validator tool, which verifies and validates your JSON data, and assists you in correcting any errors that arise due to non-compliance with JSON specifications. The ability of our tool to instantly identify exact errors is highly useful since it eliminates the need for you to click the validate button after each time you correct an error. As soon as the error is fixed, the cross (x) symbol will disappear automatically.


Here are some common questions that you may have about our JSON Validator tool:

Q: Is my JSON data secure by using your tool?

A: Yes, your JSON data remains secure as we process it in real-time. The JSON data you upload is never saved on our servers.

Q: What are the two important parts of JSON data?

A: Keys and values are the two main components of JSON. They form a key/value pair when combined. A string that is wrapped in quotation marks is always a key. Strings, numbers, boolean expressions, arrays, and objects can all be used as values.

Q: Does JSON require any knowledge of JavaScript?

A: JavaScript knowledge is not needed to use JSON. The majority of modern programming languages are compatible with it; in fact, it is language-independent.

Q: Can this tool help to identify JSON errors along with just validation?

A: Yes, the tool instantly shows the cross sign (x) alongside that particular line, where there is an error. The error description can also be found by just hovering the mouse over it. It can help you identify and fix the error in no time.

Why should you use our tool?

Since it is a web-based application, you do not need to install any software or plugins to validate JSON online. Not only this, but our tool is absolutely free and does not demand creating an account. In just a few moments, our tool verifies the JSON strings. 100% accurate results are guaranteed by our tool. If you find any difficulty in using the tool initially, you can also use the sample JSON available in the tool. All these attributes make our tool very user-friendly.
