I had downloaded two spreadsheet programs long time ago. Today I have run both spreadsheets. Together with the already published Jeks gives a nice view which is best. Verdict: none. Two spreadsheets use USA notation for decimal point and one uses the European version. All have parts which don't work. In Jeks you can make your own formula, that could be interesting. In Clean Sheets you have better layout. In between, if you can say it in that way, sits Sharp Tools. All have the trouble that you have enter the cell references manually instead of dragging it with the mouse. Sharp Tools can handle empty cells, Clean Sheets can not, you have to fill an empty cell with a zero otherwise you can't use the sum formula without error. So all spreadsheet programs have something which doesn't work or is even absent. All spreadsheet programs does have something special. But all are no match for Lotus, Open Office, Staroffice or Mesa. And then we have not mentioned Windows 3.1 programs and DOS programs.
After this intro, I have added the spreadsheet program Sharp Tools to my Java website. You can read a little more on this page

Next program is the other spreadsheet program. Have fun, stay healthy,
