This JSON Formatter allows you to view, edit, and beautify JSON code online. You have the option to either upload a JSON file using the "Upload File" button or directly paste JSON content into the designated input area. The tool checks the entered text for common JSON syntax errors and provides feedback if any issues are found.

Upon clicking the "Format JSON" button, the tool displays the resulting JSON code in a separate editor area allowing you to review, edit, or modify the converted JSON. The formatted code is presented with syntax highlighting, making it easy to distinguish between different elements and objects.

You can easily copy the formatted JSON code to the clipboard with the help of the “Copy to Clipboard” button or download to your device by clicking on the “Save as TXT” button.
