Tool description

The JSON Object Property Counter is an online JSON size calculator that analyzes JSON objects and counts their properties. This JSON element counter helps you quickly determine the JSON object length by counting all top-level properties (keys) in your data. It's useful for understanding the structure and complexity of JSON data without manually counting properties.

Features

  • Property Counting: Counts all direct properties in a JSON object to determine object length
  • Real-time Analysis: Updates the count automatically as you type or paste JSON
  • Error Detection: Validates JSON syntax and alerts if the input is invalid
