After they both read the article, Philippe Kahn and Spencer Leyton had a casual conversation where they joked, half seriously, about perhaps developing a spreadsheet to compete with Lotus Development's 1-2-3. At the time, there was absolutely no such development being undertaken by Borland. An article appeared in PC Week in 1985, quoting a maker of spreadsheet templates saying that he was in close contact with Borland, and that Borland was developing a spreadsheet. The original Borland Quattro electronic spreadsheet was a DOS program, the initial development of which was done by three Eastern Europeans, one of whom, the Hungarian Lajos Frank, was later hired by Microsoft. The common file extension of Quattro Pro spreadsheet file is. Borland changed the name to Quattro Pro for its 1990 release. Kahn by Senior VP, Spencer Leyton at a Vietnamese restaurant in Santa Cruz, was Quattro (the Italian word for 'four', a play on being one step ahead of '1-2-3'). When the product was launched in 1988, its original name, suggested to Mr. When version 1.0 was in development, it was codenamed 'Buddha' since it was meant to 'assume the Lotus position', #1 in the market.

Even with the maximum row advantage, Quattro Pro has been a distant second to Excel, in terms of sales numbers, since approximately 1996 to the present. This avoided the 65,536 row by 256 column spreadsheet limitations inherent to Microsoft Excel (prior to Excel 2007).

For years Quattro Pro had a comparative advantage, in regard to maximum row and column limits (allowing a maximum worksheet size of one million rows by 18,276 columns). It currently runs under the Windows operating system. While it is commonly said to have been the first program to use tabbed sheets, Boeing Calc actually utilized tabbed sheets earlier.

Historically, Quattro Pro used keyboard commands close to those of Lotus 1-2-3. Quattro Pro is a spreadsheet program developed by Borland and now sold by Corel, most often as part of Corel's WordPerfect Office suite.
