How to Use

Toolbar Functions:

  • Copy - Copies the formatted JSON to your clipboard.
  • Download - Saves the formatted JSON as a .json file.
  • View Toggle - Switches between interactive tree view and raw text view. Interactive view allows you to collapse and expand JSON objects and arrays.
  • Expand All - Expands all nested objects and arrays to show the complete JSON structure at once. Useful for seeing the entire JSON hierarchy without clicking through each level.
  • Collapse All - Collapses all nested objects and arrays, showing only the top level structure. Helpful for getting an overview of complex JSON data.
  • JSON Info - Shows statistics about your JSON data, including size, number of objects, arrays, and other properties.

Interactive Tree Navigation:

In the interactive view, you can navigate complex JSON structures easily:

  • Expand Node - Click on the plus icon to expand a collapsed object or array.
  • Collapse Node - Click on the minus icon to collapse an expanded object or array.

This tree view makes it easy to explore only the parts of the JSON you're interested in, especially useful for large JSON structures.

For large JSON files, use the Expand All feature to see the entire structure, and Collapse All to return to a compact overview.
