About

TreeSheets combines nested grids with text and images to organize notes, plans, and structured information. Its hierarchical layout can serve as an outliner, compact mind map, or planning sheet without requiring a conventional relational database. The Zlib-licensed desktop application provides Windows, macOS, and Linux binaries and keeps documents in local files.
