Possible disadvantages of JsonReader

    Compared to more robust tools like JSON editors or IDEs, JsonReader may lack advanced features such as schema validation, diffing, or complex querying capabilities.
  • Privacy concerns with sensitive data
    Pasting sensitive or confidential JSON data into an online tool raises potential privacy and security concerns, as users cannot fully verify how their data is handled.
  • No offline support
    As a browser-based tool, JsonReader requires an internet connection to access, which can be inconvenient when working in environments without reliable connectivity.
  • Limited for large files
    The tool may struggle with very large JSON files, potentially becoming slow or unresponsive when handling datasets that are several megabytes or more in size.
  • No collaboration or saving features

  • Privacy Concerns
    Potential privacy issues could arise from handling sensitive data, especially if data is processed online without secure protocols.
  • Reliability on Internet Connection
    Since it's an online tool, a stable internet connection is required, which can be a drawback in areas with poor connectivity.

    Copy this JSON and paste it into jsoncrack.com or any JSON tree visualizer. You'll see your AST as an interactive tree diagram. Click around. Explore the structure. See how factorial(n - 1) is represented. See how the if-expression contains three sub-expressions. Every node, every connection - it's all there. - Source: dev.to / 9 months ago

    Congratulations on the release, great to see more in this space. At the moment, I'm using https://jsoncrack.com/ which also has a VSCode extension, any chance there's something that like on your roadmap? - Source: Hacker News / over 1 year ago
  • Show HN: JSON For You โ€“ Visualize JSON in graph or table views
    It seems like a clone of https://jsoncrack.com with a different UI. I couldnโ€™t identify any significant differences aside from the reduced readability in the visualization. - Source: Hacker News / almost 2 years ago
  • Show HN: JSON For You โ€“ Visualize JSON in graph or table views
    Yes, it requires regular payment, from the SaaS perspective, since the cost is a monthly expense, adopting a subscription model is understandable. This pricing was inspired by https://jsoncrack.com/. May I ask, is there anything on the pricing page that is hard to understand? - Source: Hacker News / almost 2 years ago
