TreeSheets is open-source software for creating hierarchical spreadsheets. It lets you organize diverse data like notes, mind maps, text, images in a single spreadsheet. For example, you can put a product brainstorming session, followed by a task list to start creating the product in one file.
TreeSheets uses a proprietary CTS format to save files. So CTS files can only be opened in TreeSheets. But TreeSheets lets you export spreadsheets as HTML or JSON files for use in other programs.
To open a CTS file, go to File → Open in TreeSheets. To convert a CTS file, export it as HTML or JSON from TreeSheets.
TreeSheets replaces many tools: spreadsheets, mind maps, text editors. It is familiar like a spreadsheet but handles complex, hierarchical data. It is organized like a mind map. It has multiple dimensions like an outliner. It has structure like a text editor.
After a decade in development, TreeSheets may look dated. But its simple, distraction-free design helps you focus on your work. It suits organizing todo lists, calendars, projects, ideas, and information.
