If you’ve created a reusable Excel Spreadsheet you've basically coded a mini program. Just like developers write reusable functions, you can craft formulas and lookup tables that work across datasets. In fact, with the addition of the LAMBDA feature in 2021 (https://www.infoq.com/articles/excel-lambda-turing-complete/), Excel formula language is now Turing-Complete. This means you can program literally anything in Excel. For example this guy, you could be like this guy and program a roller-coaster in Excel (https://www.youtube.com/watch?v=IrVA1BBHFHw).
This means designing a reusable spreadsheet is all about thinking like a programmer. Modularize your work with VLOOKUP and HLOOKUP tables. Use conditional formatting and data validation to make your sheet interactive and foolproof. Throw in some macros, and you've got a powerful, adaptable tool that's ready to tackle real-world challenges.
But let's be real: crafting the perfect spreadsheet isn't always easy. Just like coding, it takes practice, patience, and a bit of trial and error. If your first attempt at a reusable spreadsheet has a few glitches or hiccups, don't sweat it. Even the most experienced programmers encounter bugs and challenges. The key is to keep refining, testing, and improving your spreadsheet until it's running like a well-oiled machine. So embrace the process, learn from your mistakes, and keep pushing the boundaries of what Excel can do. Your inner developer will thank you.
Conclusion
Although perfecting a spreadsheet requires practice and patience, overcoming glitches and challenges is part of the learning process. Keep refining, testing, and pushing the boundaries of what Excel can achieve, and your inner developer will reap the rewards.
