What it does
JSON is a "token tax" on AI apps. TOON slashes token usage by 40%, effectively expanding your LLM context window. Key Features: 1. CLI Utility: A powerful terminal tool for instant data conversion, encryption, and validation. 2. Secure Middleware: Production-ready pipelines with Fernet (AES-128) or XOR encryption. 3. Mixed-Text Support: Automatically extracts data hidden in messy LLM responses. 4. Unified Hub: Convert between JSON, XML, YAML, CSV, and TOON. Stop wasting tokens on syntax.
A powerful context reduction tool centered around converting data (JSON, YAML, XML, CSV) to the token-optimized TOON format for efficient LLM interactions.

If you've done this, you know the drill: you write CSS selectors, the site changes its layout, everything breaks at 2am, and you spend your morning rewriting parsers. LLMs seemed like the obvious fix — just throw the HTML at GPT and ask for JSON. Except in practice, it's more painful than that: - Raw HTML is full of nav bars, footers, and tracking junk that eats your token budget. A typical product page is 80% noise. - LLMs return malformed JSON more often than you'd expect, especially with…
