Did you know?
Before computers, accountants wrote ledgers by hand using the two facing pages of a book, or on oversized sheets of paper (hence the word “spreadsheet”).
An electronic spreadsheet is still working the same way, with a table of cells arranged in rows and columns. Its arithmetic and mathematical functions make it an essential tool for financial and statistical operations. But before Excel became the synonym of spreadsheets, people used other solutions.
Richard Mattessich developed the first computerized spreadsheet program in 1961. In 1969, Rene Pardo and Remy Landau co-invented LANPAR (LANguage for Programming Arrays at Random), the first application used in large companies. Electronic spreadsheets became more popular with the release of VisiCalc (created by Bricklin and Frankston), the first automated spreadsheet program to run on microcomputers and not on mainframe computers like the previous applications. And guess on which brand of computers you could find VisiCalc? On the Apple II, which became popular thanks to this program.

During the 1980s, Lotus 1-2-3 became the leader in the spreadsheet market for personal computers that ran MS-DOS the Microsoft operating system and quickly overtook VisiCalc in sales.
Microsoft developed a competing program, and the first version of Excel was released in 1985 for Apple’s Macintosh computer ( again ).
Excel was one of the first spreadsheets to use a graphical user interface, much more accessible to use than the command-line interface. Many people bought Apple Macintoshes so that they could use Excel.
The next version of Excel, and the first version to run on Microsoft’s new Windows operating system, followed in 1987 and quickly became popular.
Lotus was too slow to release a Windows version and encountered a succession of technical setbacks , allowing Excel to increase its market share and eventually become the dominant spreadsheet application in the mid-1990s.
Excel now has the largest market share on the Windows and Macintosh platforms, even if web-based spreadsheets usage is growing.

Excel files are often used to spread viruses and malware.
Cybercriminals use a vulnerability of the .xls format and can hide a virus in macros (the small programs you write to automate tasks), without being detected by an antivirus. The file is then sent to you by email, and when you open it, macros are enabled, sometimes automatically, and your system is infected With an XLS file, you don't know whether your spreadsheet contains macros or not, whereas XLSX files do not support macros. Be careful when you open .xls files from an unknown source (like you should be for any attachment anyway)!
Just like PowerPoint , there are different formats for spreadsheets. If you need to embed and execute macros, you will have to save your file as XLSM, which is the Excel Open XML Macro-Enabled file format. And if you need advanced support for templates, you can use XLTX and XLTM (which combines macro and template functionalities).
