About JSON Utils
The most comprehensive, privacy-first suite of professional JSON tools built by developers, for developers.
Our Mission
JSON Utils was created with a singular mission: to provide developers with the most comprehensive, reliable, and user-friendly JSON processing tools available on the web. We believe that working with JSON data shouldn't be complicated, slow, or require sacrificing your privacy.
In an era where data is increasingly important and API-driven architectures dominate software development, developers need tools they can trust. Tools that are fast, accurate, and respect their data privacy. That's exactly what we've built.
Our platform has grown from a simple JSON formatter into a comprehensive toolkit with over 25 professional-grade tools, serving thousands of developers worldwide. Every tool is designed with three core principles: performance, privacy, and user experience.
What We Offer
JSON Utils is more than just a collection of tools—it's a complete JSON ecosystem designed to handle every aspect of JSON data manipulation, validation, and transformation.
Core JSON Tools
Our foundation tools cover the essential JSON operations every developer needs: formatting, validation, minification, and conversion to CSV. These tools are optimized for speed and handle files up to several megabytes without performance degradation.
Advanced Converters
Transform JSON data into virtually any format you need. Generate SQL schemas, MongoDB queries, GraphQL types, OpenAPI specifications, TypeScript interfaces, and more. Our converters use intelligent type inference to create accurate, production-ready code from your JSON samples.
Analysis & Validation
Deep dive into your JSON data with our analysis tools. Compare and diff JSON documents, validate against JSON Schema specifications, analyze file sizes and optimization opportunities, find duplicates, and query with JSONPath expressions. These tools help you ensure data quality and compliance.
Developer Utilities
Specialized tools for common developer workflows: generate realistic mock data for testing, escape/unescape JSON strings, flatten nested structures, split large arrays, rename keys in bulk, and filter complex data sets. Each utility is designed to save you hours of manual work.
Our Core Values
Our Journey
What started as a simple side project to solve a personal need has evolved into a comprehensive platform serving the global developer community.
Technical Excellence
We don't just build tools—we build them right. Every aspect of JSON Utils is crafted with technical excellence in mind.
Performance Architecture
Our tools are built using vanilla JavaScript for maximum performance and minimal overhead. We employ Web Workers for large file processing, ensuring the UI remains responsive even when handling multi-megabyte JSON files. Debounced input validation provides real-time feedback without overwhelming system resources.
Privacy & Security
Everything runs client-side in your browser using modern JavaScript APIs. No data transmission to external servers means your sensitive API responses, configuration files, and business data remain completely private. We don't use analytics trackers that compromise privacy.
Accessibility Standards
WCAG 2.1 AA compliant with proper ARIA labels, keyboard navigation support, screen reader compatibility, and sufficient color contrast. Our tools are usable by everyone, including developers with disabilities. Touch targets meet minimum size requirements on mobile devices.
SEO & Discoverability
Comprehensive meta tags, structured data markup, semantic HTML, optimized page load times, and mobile-first responsive design. Every tool page is indexed and discoverable through search engines, helping developers find the exact tool they need.
Cross-Platform Compatibility
Works seamlessly across all modern browsers (Chrome, Firefox, Safari, Edge) and devices (desktop, tablet, mobile). Progressive enhancement ensures core functionality works even in older browsers, while modern features enhance the experience on cutting-edge platforms.
