• Analyze JSON from a URL: Enter a URL that returns a JSON response to fetch and analyze the data.
• Analyze JSON from Text: Paste or write JSON directly into the textarea, and then analyze or extract the keys from the JSON.
• Save State: You can save the current state of the page (URL, JSON text, etc.) to a file or browser local storage, and recover it later.
• Copy to Clipboard: Use the "Copy to Clipboard" buttons to quickly copy parsed JSON or extracted keys.
