About MyWebUtils
MyWebUtils is a comprehensive online toolbox designed for developers and analysts, delivering over 50 free utilities that run entirely in the browser with no signup required. Among these is a JSON ↔ TOON converter—a tool that transforms standard JSON into TOON format, which is optimized for large language model (LLM) ingestion by reducing token usage and improving context-efficiency. All processing is client-side, preserving privacy and enabling instant conversion. The platform also offers format converters (CSV ↔ JSON, YAML ↔ JSON), validators, diff tools, text utilities, image tools, QR/barcode generators, finance calculators, network and time tools, and more.
