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

Tabular Arrays

Uniform arrays are converted to tabular format with field names declared once, reducing redundancy by 40-60%

Key Folding

Nested single-key objects are collapsed into dotted paths (e.g., "user.name")

Whitespace Reduction

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
