TOON (Token-Optimized Object Notation) is a compact format that reduces token usage for AI models. It's especially effective for tabular data, converting arrays of objects into a CSV-like format while preserving structure.

Key Features:

  • Tabular arrays converted to column-based format
  • Length markers for array sizes
  • Configurable delimiters and indentation
  • Can save 30-60% tokens compared to JSON
