I need a simple spreadsheet editor. I can use BIFF to create an initial spreadsheet but then I need a simple spreadsheet editor.
What would you guys recommend. I need a free spreadsheet editor that is small and has the usual cut/copy/paste features.
Thanks for any help.

Here are the program steps that would be involved:
1. User enters a math expression. (Uses thinbasic UI).
2. thinbasic script creates spreadsheet based on entered math expression.
3. Each row of spreadsheet involves a variable from entered math expression.
4. User edits spreadsheet data.
5. User clicks on [Submit] button when done editing spreadsheet.
6. thinbasic processes entered spreadsheet. Creates a test report with charts etc.
7. User can save all info in a suitable file. Can file save/exit etc.
