#Microsoft Excel

One incredibly skilled YouTuber called Inkbox embarked upon the journey to create the concept of a CPU inside of Microsoft Excel, a spreadsheet program. The result is super impressive, and the creator even made EXCEL-ASM 16 which is a custom assembly language to write programs for this Excel-based CPU. The specs are 16-bit, 2-3Hz speed, and 128KB RAM. He also made a 128x128 16-color display on the Excel program to show output.
