What it does

JSON → TOON Converter transforms JSON into TOON (Token-Oriented Object Notation), a compact format designed for LLM workflows. It reduces token usage by removing JSON verbosity like repeated keys and brackets. Use it to optimize prompts, AI agents, RAG payloads, and API calls. Runs fully in browser with no signup or backend.

Free online JSON to TOON converter. Convert JSON to Token-Oriented Object Notation — a compact format that can reduce LLM prompt payload size. Browser-only.

Convert JSON to TOON — an emerging compact serialization style designed to reduce token count and payload size in LLM prompts. Paste standard JSON and get the TOON equivalent instantly in your browser, ready to drop into a prompt or context window. TOON produces one of four output patterns depending on the shape of your JSON. Knowing which pattern applies helps you predict how much the output will shrink before you convert. Every key in a JSON object becomes an indented key: value line. Nesting adds 2 spaces per level. String values that contain special characters ( : , # [ ] { } ), look like literals ( null , true , false , or a number), or have leading/trailing whitespace are…from jsondevtools.org

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
