Advanced JSON Formatter
What the JSON Formatter App Does
This app helps you work with JSON data easily by:
- Input / Paste Raw JSON
You paste or type any JSON text into the input box.
- Validate JSON Syntax
The app checks if your JSON is valid. If there are errors, it tells you exactly what and where the problem is.
- Format / Beautify JSON
It formats your JSON with proper indentation and line breaks, making it easy to read.
- Minify JSON
Removes all unnecessary spaces and line breaks to make JSON compact (good for saving bandwidth).
- Show JSON Tree View
Displays your JSON data as a collapsible tree structure so you can explore nested objects and arrays visually.
- Copy Formatted JSON to Clipboard
With one click, copy your formatted JSON to share or paste somewhere else.
- Download JSON File
Download the formatted JSON as a .json
file to your computer.
- Error Reporting
Shows detailed error messages if the JSON is invalid, including line and character info.
How to Use the App
Paste or type your JSON in the large text area labeled "Paste/Edit Raw JSON".
If the JSON is valid, the tree view below will show the structure of your JSON in an expandable format.
To beautify (format) the JSON:
- Select your preferred indentation (2 spaces, 4 spaces, 8 spaces, or tab) from the dropdown.
- Click Beautify JSON. Your JSON will be reformatted nicely with the chosen indentation.
To minify the JSON (remove all unnecessary whitespace):
- Click the Minify JSON button. Your JSON will be compressed into one line (if possible).
To copy the current JSON content to clipboard, click the Copy Output button.
To download the JSON as a file:
- Click the Download JSON button. This saves the JSON as
formatted.json
on your computer.
If the JSON is invalid, you will see an error message in red under the buttons explaining the issue, so you can fix it.
You can also explore the JSON structure visually in the JSON Tree Viewer below the controls by clicking on nodes to expand/collapse objects or arrays.
