Summarize Large JSON Files Instantly


The Challenge of scale

Opening a 50MB JSON file can crash simple editors. You need to know "Does this file contain the 'user_id' field?" without scrolling through a million lines.


Structural Summarization

Our tool calculates:

  • **Total Keys:** Count of all properties.
  • **Max Depth:** How nested the object is.
  • **Data Types:** Counts of strings, numbers, booleans, etc.

    • This "metadata" view gives you a health check of your data payload instantly.
