AI JSON Analyzer
Analyze JSON structure and security risks
Features
Structure Analysis
Paste JSON to instantly analyze the root type, top-level field count, recursive field total and maximum nesting depth.
Field Type Statistics
Counts the type distribution of all fields (object/array/string/number/boolean/null) and shows array element type composition.
Sensitive Field Detection
Automatically detects common sensitive fields (password, token, API key, card numbers, ID numbers, phone, email) with high/notice risk levels.
Local Processing · Private
All analysis happens locally in your browser. Data is never uploaded, safe for JSON containing sensitive information.
How to Use
Step 1: Paste JSON
Paste JSON data into the input area, or click "Load Sample" (includes nested objects, arrays and sensitive fields).
Step 2: Start analysis
Click "Analyze" to get a structure summary, type distribution and security alerts. Invalid JSON shows error line/column and context.
Step 3: Copy the result
Click "Copy Result" to copy the analysis summary to your clipboard for documentation or reports.
常见问题
Is the AI JSON Analyzer free?
Yes, completely free with no registration or usage limits.
Will my JSON be uploaded to a server?
No. Structure analysis happens locally in your browser. Your data never leaves your device.
How is the maximum nesting depth calculated?
The root node counts as level 1, and each level deeper adds 1. For example, {"a":{"b":1}} has a maximum depth of 3.
What rules does sensitive-field detection cover?
Common sensitive fields: password/passwd, secret, token, apiKey, authorization, credit card numbers, ID numbers, SSN, phone, email, birthday, address — flagged as high risk or notice.
