JSON Analyzer Features
Deep statistical profiling and dataset quality auditing
📊 Data Type Distribution
Calculates exact counts and percentages for strings, numbers, booleans, nulls, objects, and arrays.
⚡ Structure Complexity Score
Computes an automated 1-100 complexity metric based on nesting depth, key cardinality, and object density.
🔑 Key Frequency Analysis
Identifies top recurring keys across nested objects and tracks key reuse frequencies.
🛡️ Data Quality Audit
Flags data anomalies like high null density, excessive nesting depth, empty objects, and duplicate keys.
📋 Executive Summary Export
Generates downloadable text/markdown reports summarizing dataset metrics for documentation.
🔒 100% Browser Privacy
All data processing is executed in local browser JavaScript. Zero external network requests.

Frequently Asked Questions
How does the JSON Analyzer differ from the JSON Viewer?
While the JSON Viewer focuses on tree navigation and path inspection, the JSON Analyzer performs deep statistical profiling, data type distribution analysis, complexity scoring, key frequency tracking, and automated quality auditing.
Is my JSON payload safe during analysis?
Yes, 100%. All parsing, metric calculations, and quality report generation happen entirely within your local browser memory. Zero data is transmitted to external servers.
What is the JSON Complexity Score?
The Complexity Score (1-100) measures dataset structural intricacy based on maximum nesting depth, key cardinality, object/array density, and type heterogeneity.
Can I export the analysis report?
Yes! Click Copy Report to copy the formatted text analysis or click Download Report to save it as a text file.
