Ben Bricklin and Bob Frankston
Dan Bricklin, along with a man called Bob Frankston, invented a program called VisiCalc in 1978. It was the first electronic spreadsheet. In the following years, others created their own electronic spreadsheets. Microsoft Excel was first launched in 1985. So it was inspired by the work of Dan Bricklin and others.
The first computerised spreadsheet was launched by Dan Bricklin and Bob Frankston in 1979. It was called Visicalc. Microsoft were just one of several companies to bring out their own spreadsheet programs after that. Excel was first launched in 1985, but Microsoft had other ones before that, like Multiplan.
Excel is a spreadsheet developed by Microsoft but is by no means the first spreadsheet. The very first spreadsheet was developed (or invented) by Dan Bricklin and Bob Frankston called VisiCalc. VisiCalc was a spreadsheet written to operate on the Apple II computer and was released in 1979. The program was sold to Lotus who developed Lotus 123 from the VisiCalc principle. Lotus 123 was released in 1983. Excel, first released in 1987, is a development of the early spreadsheets and therefore cannot strictly be classified as an invention. Excel is far more powerful than VisiCalc but that is also a result of development over the years that Microsoft have been working on the product, and the increase in computing power. Dan Bricklin and Bob Frankston never patented the product because software patents were almost unheard of in the 70s.
The first electronic spreadsheet was called VisiCalc, invented by Dan Bricklin and Bob Frankston in 1978. Other companies then began to copy their idea. Microsoft created one called Multiplan, but it did not do well, and in 1985 they launched their first version of Excel. Many people working at Microsoft would have been involved in creating it.
The first Spreasheet was called Visicalc, invented in 1978 by Bob Frankston and Dan Bricklin. Other spreadsheet applications followed, like Lotus 1-2-3.The first version of Microsoft Excel came out in 1985 for the Mac, and a version for a PC in 1987.
Microsoft released the first version of Excel for the Mac in 1985, and the first Windows version (numbered 2.05 to line up with the Mac and bundled with a run-time Windows environment) in November 1987.

Microsoft Office was invented in 1988 by Microsoft. It was not released until November 23, 1990. The initial package consisted of Microsoft Word, Microsoft Excel and Microsoft PowerPoint.
Microsoft Excel doesn't have an invention date per-say. It was sold to them by another company under a different name Microsoft released it under a different name and with major improvement in 1987.
