Simple Spreadsheet - Version 1.0 The Simple Spreadsheet is a bare-bones spreadsheet available for free, including sources. I wrote it because I needed a spreadsheet with minimal features and just couldn't bring myself to spend hundreds of dollars buying one. So I wrote Simple SpreadSheet in about two days. It doesn't do even 10% of what the full-featured products do, but if you want only the basics, here is a free spreadsheet for you.
