Free Form Data Organizer
The ultimate replacement for spreadsheets, mind mappers, outliners, PIMs, text editors and small databases.
Suitable for any kind of data organization, such as Todo lists, calendars, project management, brainstorming, organizing ideas, planning, requirements gathering, presentation of information, etc.
It's like a spreadsheet, immediately familiar, but much more suitable for complex data because it's hierarchical.
Have a quick look at what the application looks like on the screenshots page, see how easy it is to use in the tutorial (out of date, the live in-app tutorial works much better!), then give it a download (above).
TreeSheets is exceptionally small & fast, so can sit in your system tray at all times: with several documents loaded representing the equivalent of almost 100 pages of text, it uses only 5MB of memory on Windows 7 (!)
TreeSheets is free & open source. Enjoy!
