Possible disadvantages of JSONView

  • Limited Features
    Compared to full-fledged JSON editors, JSONView offers limited functionality, focusing mainly on formatting and displaying JSON data.

  • Browser Compatibility
    JSONView is primarily designed for Google Chrome, which may limit its usability in other browsers without similar extensions.
