Technical Security Whitepaper

Executive Summary

FormatJSONOnline adopts a privacy-first architecture where the vast majority of operations occur client-side (in your browser). For operations that require server processing (AI features), we implement strict data handling policies including zero retention, encryption-in-transit, and no use of data for model training.

1. Architecture Overview

Client-Side Processing

The following operations execute entirely within your browser using Web Workers and Service Workers:

  • ✓ JSON Formatting & Beautification
  • ✓ JSON Validation & Syntax Checking
  • ✓ JSON Minification
  • ✓ JSON to/from CSV, XML, YAML conversion
  • ✓ JSON Merge, Flatten, Filter operations
  • ✓ JSON to TypeScript/Python/Go type generation
  • ✓ Diff/Compare operations
  • ✓ Size calculations & analysis
  • ✓ Escape/Unescape operations
  • ✓ Path finder & JSONPath queries

Data Security Guarantee: Your JSON never leaves your device. All processing occurs in your browser's memory with no network transmission.

Server-Side Processing (AI Features)

The following features require server-side processing:

  • ✓ AI JSON Generator (creates mock JSON based on schema)
  • ✓ AI Error Fixer (suggests fixes for invalid JSON)
  • ✓ JSON Translator (translates between languages)
  • ✓ Schema Generation (infers schema from JSON)

Data Handling: When you use these features, your JSON and prompts are transmitted via encrypted HTTPS to our backend. We use third-party AI APIs (OpenAI, Anthropic, etc.) with enterprise agreements that prohibit data retention and model training.

3. AI Safety & Guardrails

⚠️ Important Disclaimers

  • No Guarantee of Accuracy: AI-generated JSON, fixes, and schemas are not guaranteed to be correct. Always review output before using in production.
  • User Responsibility: You are responsible for validating all AI-generated content. FormatJSONOnline assumes no liability for errors or security issues in AI output.
  • No Training Usage: Your inputs are never used to train or improve AI models. We have contractual guarantees from all API providers.
  • Rate Limits: AI features are rate-limited to prevent abuse. Excessive usage may result in temporary restrictions.

User Warnings in UI

All AI features display clear warnings:
