JSON Token Optimizer
Optimize JSON for LLM token efficiency - reduce tokens by 30-60%
Experimental Tool
This LLM & AI tool is experimental and under active development. Features and accuracy may vary. Use with caution in production environments.
Standard JSON Input
Paste your JSON data (works best with uniform arrays)
Optimized Output
Token-efficient format for LLM consumption
Optimization Techniques
Uniform arrays are converted to tabular format with field names declared once, reducing redundancy by 40-60%
Nested single-key objects are collapsed into dotted paths (e.g., "user.name")
Minimal indentation and strategic formatting for readability without bloat
How to Use
1. Paste your JSON data into the input field
2. Click "Optimize" to apply token-efficient transformations
3. Review the token savings and copy the optimized output
4. Use the optimized format when sending data to LLMs (ChatGPT, Claude, etc.)
Best Use Cases
Uniform Arrays: Lists of users, products, transactions where all objects have the same fields
API Responses: Large datasets from APIs with consistent structure
Database Exports: Query results with repeated field names
LLM Context: When passing structured data to language models
