OGF: Open Grid Format

OGF is an open, declarative JSON format for describing interactive data grids. It defines structure, data, behavior, and rendering intent — in a portable, renderer-agnostic way.

The format behind powerful grid tools — built for developers who need control, transparency, and interoperability.

💡 What is OGF?

OGF (Open Grid Format) is a neutral, open format for defining editable, structured grid data. Use OGF documents to:

• Describe cell data, types, formulas, filters and layout
• Serialize grid configurations into .ogf.json files
• Render grids across different frameworks and tools

✨ Key features

• Open & portable: based on JSON, license-free
• Renderer-agnostic: HTML, Canvas, React, CLI, etc.
• Composable: opt-in modules like formulas, filters, validation
• Community-oriented: open spec, open contributions

🔧 Supported by:

• Grid Toolkit — the first full implementation of OGF
• Community tools (coming soon)
• Spreadsheet converters (planned)
