One approach is to record a macro by going to the 'Developer' tab, clicking on 'Record Macro', performing the actions you want to automate, and then stopping the recording. You can assign a keyboard shortcut to the macro for easy access. Another option is to write VBA code directly by opening the Visual Basic Editor and using the 'Sub' and 'End Sub' keywords to define a macro. This gives you more control and flexibility but requires knowledge of VBA programming. You can also explore using the Excel object model to interact with workbooks, worksheets, and cells programmatically.

Another way to automate repetitive tasks is by using Excel's Power Query feature. With Power Query, you can connect to various data sources, transform and clean the data, and then load it into Excel. This eliminates the need to manually perform data cleaning and transformation steps every time the data updates.

If you are comfortable with programming in other languages like Python or C#, you can leverage libraries and APIs to interact with Excel programmatically. For example, in Python, you can use libraries like openpyxl or pandas to read and write data to Excel files, perform calculations, or even create dynamic reports.

Additionally, Excel has built-in functions like INDEX, VLOOKUP, and IF statements that can help automate tasks. By combining these functions with logical operators and conditional formatting, you can create powerful dynamic spreadsheets that update automatically based on changing data or conditions.
