Best JSON Viewer Online

Our JSON Viewer will help you see how your JSON strings work. The tool validates your JSON structure according to your requirements and helps you fix any errors. The tool can determine whether your JSON data is valid and will give you the desired results or not, in just a single click.

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 gives 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 some requirements may be overlooked due to human error. But don’t worry, our JSON Viewer tool helps you easily read your JSON data in a structured manner. You can expand or shrink nodes as you need. The tool can help you ensure that your written JSON verifies the desired results or not. Any errors are pointed out in real-time, so they can be fixed instantly.

  1. 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.
  2. You can then click the View button again to view the structure of your JSON data.
  3. If you want to expand or contract a node or subnode, you have to click on the arrow sign alongside its name.

  6. You can make changes and then click the View button again to view the structure of your updated JSON data.
  7. You can copy the final JSON, and save it in your project files.
  8. If you wish to change the JSON and want to view 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 Viewing 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 verify if the JSON data meets the desired objectives or not. 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 Viewer tool, which helps you read and verify your JSON data, and assists you in correcting any errors. The ability of our tool to instantly identify exact errors is highly useful since it eliminates the need for you to click the View button after each time you correct an error. Moreover, the tool can help you understand and verify the designed JSON structure and allows you to expand or contract the nodes and subnodes as you need.
