Complete History of Microsoft Excel

📜 The Complete, Deep, and Enjoyable History of Microsoft Excel

If you think Excel is just a grid of rows and columns, think again. This is the full story of Excel — from the time spreadsheets were done with pen and paper, to the powerful software we have today. By the end of this history, you'll know not only what Excel is but also how it came to be, why it was created, the programming languages behind it, how it compiles, and even how you could build your own Excel-like app.


1. Before Excel: Life in the Age of Paper Spreadsheets

Before computers, “spreadsheets” were literally sheets of paper used by accountants, bookkeepers, and managers to calculate budgets, track inventories, or record transactions. You had to do math by hand (or with calculators). If you made one mistake on a large sheet, you had to redo a lot of work. This process was slow, repetitive, and error-prone.

The first leap forward came with VisiCalc in 1979 — the first electronic spreadsheet for the Apple II computer. Created by Dan Bricklin and Bob Frankston, VisiCalc turned accounting into a fast, interactive process. It became the “killer app” for early PCs.


2. Why Microsoft Wanted to Create Excel

By the early 1980s, there were a few spreadsheet programs: VisiCalc, Lotus 1-2-3, and Multiplan (Microsoft’s first spreadsheet). But Lotus 1-2-3 dominated because it was faster and more powerful.

Microsoft saw an opportunity: Create a spreadsheet that was graphical, user-friendly, and integrated with the growing GUI world (like the Macintosh). They wanted Excel to be:

  • Faster and more efficient than competitors
  • Visually appealing with charts, colors, and formatting
  • Built for the future of GUI-based computing
  • Compatible with Windows and Macintosh

3. Birth of Microsoft Excel

Excel 1.0 was released for the Macintosh in 1985. Why Mac first? Because Windows wasn’t ready for complex GUIs, and the Mac already had a strong graphics interface.

In 1987, Microsoft released Excel for Windows (Excel 2.0 — they skipped “1” to match the Mac version). From that point, Excel began to outpace Lotus 1-2-3 because Windows PCs were booming.


4. The Programming Languages Behind Excel

Excel was primarily developed in C in the early versions because C allowed efficient low-level control while still being portable across systems. Over the years, Microsoft incorporated:

  • C++ — For object-oriented structure and performance improvements
  • Assembly — For highly optimized routines (especially in calculation engine)
  • Visual Basic for Applications (VBA) — Introduced in Excel 5.0 (1993) to let users automate tasks
  • C# and .NET components — In modern integrations with Office 365 and cloud features

5. How Excel is Compiled

Early Excel was compiled using Microsoft’s own C compilers targeting specific CPU architectures like the Motorola 68000 (Mac) and Intel x86 (PC). The compilation process looked like this:

  1. Source code written in C/C++
  2. Compiled into object code using a compiler
  3. Linked with libraries (graphics, math, OS APIs)
  4. Packaged into an executable (.EXE for Windows, Mac application bundle for Mac)

Modern Excel builds involve millions of lines of code, compiled with advanced build systems, automated testing, and cross-platform deployment pipelines.


6. Is Excel Open Source?

No. Microsoft Excel is proprietary software. Its source code is not available to the public. However, Microsoft has published open formats like Office Open XML (.xlsx) so others can read and write Excel files.

For open-source alternatives, you can look at LibreOffice Calc, Apache OpenOffice, or Gnumeric.


7. How to Build Your Own Excel-Like App

If you wanted to create your own spreadsheet application, you’d need to combine:

  • Grid Rendering — Display rows, columns, and cells
  • Cell Data Structures — Store values, formulas, formatting
  • Formula Parser & Calculation Engine — Interpret functions like =SUM(A1:A5)
  • File Import/Export — Save as .xlsx, .csv, etc.
  • UI Controls — Toolbars, charts, menus

Example: Simple pseudo-code for a cell calculation

function calculateCell(formula) {
  tokens = parse(formula);
  return evaluate(tokens);
}


8. Timeline of Excel Versions

  • 1985 — Excel 1.0 for Macintosh
  • 1987 — Excel 2.0 for Windows
  • 1990 — Excel 3.0 (introduced toolbars, drawing, outlines)
  • 1993 — Excel 5.0 (VBA introduced)
  • 2000 — Excel 2000 (HTML support)
  • 2007 — New ribbon UI, .xlsx format
  • 2013 — Cloud integration with OneDrive
  • 2020+ — Excel for the web with AI features

9. Real-World Impact

Excel is used everywhere: finance, engineering, education, science, inventory, and even sports analysis. In fact, NASA has admitted to using Excel for some data analysis tasks. It’s so universal that “Excel skills” are listed in millions of job descriptions worldwide.


10. Conclusion

Excel’s story is one of innovation, competition, and adaptation. From replacing paper ledgers to integrating with AI in the cloud, Excel has shaped how humans work with data for nearly four decades. Understanding its history and design is the first step to building something even better.

2. Excel Application Overview

Excel is a spreadsheet software that allows users to store, organize, analyze, and visualize data in tabular form. Key components:

  • Workbook: An Excel file (.xlsx, .xlsm, etc.). Contains multiple worksheets.
  • Worksheet: A single sheet inside a workbook, composed of rows and columns.
  • Cells: Intersection of a row and column (e.g., A1).
  • Range: A group of cells (e.g., A1:C10).
  • Row: Horizontal set of cells identified by numbers.
  • Column: Vertical set of cells identified by letters.
Example: To select the first 10 rows and first 3 columns: Click on cell A1, drag to C10 — the selected area is your range A1:C10.

3. Ribbon, Tabs, and Groups

  • Ribbon: The horizontal strip at the top of Excel containing tabs.
  • Tabs: Organized sections like Home, Insert, Page Layout, Formulas, Data, Review, View.
