Format Comparison Tool

Compare token usage across JSON, TOON, YAML, and CSV formats

Input JSON Data

Paste your JSON to compare formats

Automate Format Comparison

Use our package to compare formats programmatically

1. Install the package

npm install @toonparse/core

2. Use in your code

import { compareFormats } from '@toonparse/core';

const data = {
  users: [
    { id: 1, name: 'Alice', role: 'admin' },
    { id: 2, name: 'Bob', role: 'user' }
  ]
};

const comparison = compareFormats(data);

console.log(`JSON: ${comparison.jsonTokens} tokens`);
console.log(`TOON: ${comparison.toonTokens} tokens`);
console.log(`Savings: ${comparison.savingsPercent}%`);
// Output:
// JSON: 50 tokens
// TOON: 20 tokens
// Savings: 60%

💡 The @toonparse/core package includes token counting, format comparison, and eligibility checking utilities.

Understanding the Comparison

This tool helps you understand which format is most efficient for your specific data:

TOON - Best for uniform arrays, 30-60% savings over JSON
CSV - Most compact for pure tabular data, but limited functionality
YAML - Good balance of readability and compactness
JSON - Universal standard, but verbose for LLM prompts
