Microsoft Excel was created at Microsoft by a team led by Charles Simonyi , with key roles played by Jabe Blumenthal (project lead) and Doug Klunder (lead developer).

Quick Scoop

  • Charles Simonyi is often called the “father of Excel” because he led development of Microsoft’s early productivity apps, including Excel.
  • Excel was first released for the Apple Macintosh in 1985, then for Windows in 1987.
  • The concept of the electronic spreadsheet itself was invented earlier by Dan Bricklin and Bob Frankston, creators of VisiCalc, which inspired later tools like Excel.

So who “invented Excel”?

If you mean the specific Microsoft product “Microsoft Excel”:

  • It was developed at Microsoft in the mid‑1980s.
  • Charles Simonyi headed the applications group and is credited as a central figure behind Excel, to the point some sources call him Excel’s “father.”
  • Jabe Blumenthal served as project lead and Doug Klunder as lead developer for Excel 1.0.

If you mean the broader spreadsheet idea:

  • Professor Richard Mattessich described spreadsheet‑like budgeting software in 1964, providing early theoretical foundations.
  • Dan Bricklin and Bob Frankston built VisiCalc (1979), widely recognized as the first successful electronic spreadsheet and the direct ancestor of modern spreadsheets like Excel.

Mini timeline

  1. 1964 – Richard Mattessich publishes work describing a computer‑based budgeting “spreadsheet” model.
  1. 1979 – Dan Bricklin and Bob Frankston release VisiCalc, the first major electronic spreadsheet.
  1. 1985 – Microsoft releases Excel 1.0 for Macintosh.
  1. 1987 – Excel is released for Windows and begins to overtake rivals like Lotus 1‑2‑3.

Forum-style take

If you’re asking “who invented Excel,” the clean answer is: a Microsoft team led by Charles Simonyi, with Jabe Blumenthal and Doug Klunder as key builders.

If you’re asking “who invented spreadsheets,” that credit usually goes to Dan Bricklin and Bob Frankston (VisiCalc), building on even earlier academic work by Richard Mattessich.

What you mean Names to know Why they matter
“Who invented Excel?” Charles Simonyi, Jabe Blumenthal, Doug Klunder Led and developed Microsoft Excel in the 1980s.
“Who invented spreadsheets?” Dan Bricklin, Bob Frankston (plus early work by Richard Mattessich) Created VisiCalc and the modern spreadsheet concept Excel later built on.
**TL;DR:** Excel itself was built at Microsoft, chiefly under Charles Simonyi’s leadership, but it stands on the earlier spreadsheet breakthrough of Dan Bricklin and Bob Frankston’s VisiCalc.
