JSON TOON
Token-Oriented Object Notation
Transform your JSON data into optimized TOON format in seconds - cut down LLM token consumption by up to 60% and save thousands of dollars on API costs
Optimize your AI prompts with TOON format. Remove redundant JSON syntax, preserve data structure, and save thousands on API costs with GPT-5, GPT-4, Claude, Gemini, and other major LLM providers. All processing happens locally in your browser - your data never leaves your device.
Features
Powerful features designed for modern LLM workflows. Optimize your AI interactions, reduce costs, and improve performance with enterprise-grade JSON2TOON conversion.
Up to 60% Token Reduction
Key Statistics
Overview
Our JSON2TOON converter achieves proven token savings across all major LLM providers including OpenAI, Anthropic, and Google.
Tested on thousands of real-world JSON structures, our converter consistently delivers up to 60% token reduction. For a typical API call with 100,000 tokens, you could save up to 60,000 tokens per request, translating to significant cost reductions at scale.
How It Works
Convert your JSON data in just 4 simple steps. Our intuitive workflow makes token optimization accessible to developers of all skill levels, from beginners to enterprise teams managing millions of API calls.
Paste Your JSON
Copy your JSON data from any source - API response, database query, or configuration file. Paste it into the converter's input field. Our converter handles any valid JSON structure including nested objects, arrays, mixed types, and complex data hierarchies with unlimited depth.
No preprocessing required - paste and go. Support for JSON from REST APIs, GraphQL responses, MongoDB exports, AWS S3, Firebase, and more.
Works with: Minified JSON, pretty-printed JSON, and even single-line formats.
Compatible sources: REST APIs, GraphQL, MongoDB, AWS S3, Firebase, PostgreSQL JSONB, and any JSON-compatible data source.
Validation: Automatic JSON validation with helpful error messages if invalid.
Click Convert
Press the 'Convert to TOON' button and watch the magic happen. Our converter instantly transforms your data using the optimized TOON format. The conversion algorithm intelligently identifies patterns, removes redundant syntax, and optimizes structure while preserving all data semantics.
Speed: Large JSON files process in milliseconds, with real-time progress for files exceeding 10MB.
Advanced parsing: Built with techniques that automatically detect tabular data, uniform arrays, and repetitive structures for maximum token reduction.
Pattern recognition: Intelligently identifies repeated structures and optimizes them for token efficiency.
Semantic preservation: All data meaning and structure is preserved while reducing token count by up to 60%.
Review Savings
Check the conversion statistics to see exactly how many tokens you saved. See percentage reduction, total tokens saved, and final token count. Detailed metrics help you understand the impact and calculate potential cost savings.
Metrics: Percentage reduction, total tokens saved, and final token count displayed in real-time.
Cost analysis: Estimate API call reductions and track optimization effectiveness over time.
Reporting: Perfect for reporting to stakeholders and demonstrating ROI. Compare savings across different JSON structures.
Export: Track optimization trends and export statistics for financial planning and budget allocation.
Copy and Use
Click 'Copy to Clipboard' to get your TOON formatted data. Use it directly in your LLM prompts, API calls, or data pipelines. The TOON output is ready to paste into ChatGPT, Claude, Gemini, GPT-5, or any LLM interface.
No formatting needed: The TOON output is ready to paste into any LLM interface immediately.
Platform compatibility: Works with ChatGPT, Claude, Gemini, GPT-5, and all major AI platforms.
Integration: Compatible with automated workflows, CI/CD pipelines, production applications, and enterprise systems.
Language support: Works seamlessly with Python scripts, Node.js applications, and cloud functions.
Benefits
Why developers choose our JSON2TOON converter. Join thousands of developers, data scientists, and AI engineers who trust our tool to optimize their LLM interactions and reduce costs.
Save API Costs
With GPT-4 costing $30 per million tokens, converting JSON2TOON can save thousands in API expenses. Independent benchmarks show up to 60% token reduction on average. For teams processing 10 million tokens monthly, that's potential savings of up to $180,000 annually. Even small-scale projects see immediate cost benefits. Calculate your savings: if you send 100,000 tokens daily, TOON format could save you up to $54,000 per year.
Improve Performance
Benchmarks show LLMs achieve 86.6% accuracy with TOON compared to 83.2% with JSON. The optimized format not only saves tokens but can improve model performance. Studies across multiple LLM providers reveal that TOON's cleaner structure reduces parsing errors, improves context understanding, and enables more accurate responses. Faster response times also mean better user experiences in production applications.
Secure & Private
All conversion happens locally in your browser. Your JSON data never leaves your device, making it safe for sensitive information including API keys and proprietary data. Perfect for healthcare, finance, legal, and enterprise environments with strict compliance requirements. No data transmission means zero risk of breaches, leaks, or unauthorized access. Even your browser history doesn't store sensitive conversion data - complete privacy from start to finish.
Universal Compatibility
Works with all major LLM providers including OpenAI (GPT-3.5, GPT-4, GPT-4 Turbo), Anthropic (Claude 3 Opus, Sonnet, Haiku), Google (Gemini Pro, Ultra), Cohere, and open-source models like Llama 2 and Mistral. Consistent token savings across all providers regardless of their tokenization algorithms. Tested and verified with real API responses to ensure compatibility. Future-proof design means new LLM providers work seamlessly too.
