2. Lotus 1-2-3

Lotus 1-2-3 is an exciting product and is very different than its competitors, but definitely one of the best spreadsheet software programs out there. Lotus 1-2-3 is definitely compatible with Excel products since we had no problems saving spreadsheets in Excel formats nor did we have trouble opening Excel spreadsheets with Lotus 1-2-3.The Lotus 1-2-3 interface is refreshing since it’s different than all of the other interfaces.
