Foreign calculations in Excel can be done using the same technique. Let’s say I am asking Excel to create a population projection sheet. To be more precise, a VBA code can be used to achieve this. The VBA code not only works in PowerPoint, but also in Ford and Excel. This programming technique can be used in Excel without even knowing programming. However, knowing programming can be beneficial in case of errors. Understanding the language of the computer is essential to identify and rectify errors. In the past, coding was necessary for writing codes, but now it is important to at least have a basic understanding of coding to read codes. There is a difference between writing and reading codes. ChatGPT can write code, but it may contain errors as it is ultimately a machine. Knowing coding allows you to rectify those mistakes on your own or ask ChatGPT to correct them. Now, let’s create a population projection sheet. This sheet does not require any knowledge of Excel or coding. We will use a VBA code for MS Excel to automatically calculate the population for future decades using arithmetic, geometric, and incremental methods. Simply write the VBA code and hit the enter button to generate the code. Copy the code and open Excel. Go to the developer tab, choose visual basics, select the module, and paste the code. It’s as simple as that. Remember to input the data for three decadal censuses. Additionally, a graph can be created using the generated code. Save the file and use the population projection sheet.
