Pure Functional Programming in Excel

Explore pure functional programming concepts applied to Excel in this 43-minute conference talk from GOTO Amsterdam 2016. Discover why Excel is considered the world's most popular programming language and how it can be leveraged for powerful computational tasks. Learn about Excel's Turing completeness, software engineering challenges in spreadsheets, and functional programming techniques using formulas and array functions. Dive into topics such as error handling, dynamic programming, code smells, and dependencies in Excel. Gain insights on visualizing data, working with external worksheets, and addressing common spreadsheet issues. Engage with live programming demonstrations and real-world problem-solving examples throughout the presentation.
