Free Spreadsheet Programs

This month Web Tour complements our spreadsheet theme.

Possibly you think Microsoft Excel is the only available and capable spreadsheet software. Then think again. There are quite a number of free/open-source spreadsheet programs that are good and compare favorably with Excel. Calc Calc is a segment of the software package. It is similar to Microsoft Excel, with many similar features. Calc is capable of opening and saving spreadsheets in Microsoft Excel file format. It provides a number of features Excel does not include in the graphical area. Calc can convert spreadsheets to PDF files.


Gnumeric has Windows installers available. It is intended to be a free replacement for proprietary spreadsheet programs. Gnumeric's accuracy has helped establish itself for statistical analysis and other scientific tasks.

Simple Spreadsheet

Simple Spreadsheet is a web-based spreadsheet program. It is released under the GNU General Public License, and is thus free software. It includes formulas, charts, formats, cell/row merging, cell locking, keyboard navigation, etc.


WikiCalk is a web application created by Dan Bricklin who, 27 years earlier, created VisiCalc, the first spreadsheet. It is currently, as Version 1.0, available for Windows, Mac, and Llnux/Unix.


All of the Web Tour sites in the newsletter are archived and instantly available right here on our website. Don't waste time-consuming typing of the site addresses. Just click, and you are there.
