If you have a huge list of data in Excel, there are a few different ways that you can sort it. The first way is to use the built-in sorting features in Excel. To do this, select the data that you want to sort, and then click on the "Data" tab. In the "Sort & Filter" section, click on the "Sort" button. This will open up the Sort dialog box. In this dialog box, you can choose the column that you want to sort by, as well as the order (ascending or descending). You can also add additional levels of sorting, if you want. For example, you could sort by last name, and then within each last name, sort by first name. To do this, just click on the "Add Level" button in the Sort dialog box.
Another way to sort huge lists in Excel is to use a macro. Macros are little programs that you can write in Excel to automate tasks. To write a macro, you need to use the Visual Basic for Applications (VBA) language. Don't worry if you've never written a macro before - it's not difficult, and there are plenty of resources available online to help you get started. Once you've written your macro, you can run it by clicking on the "Macros" button on the "Developer" tab (this tab is only visible if you have enabled the Developer tab in Excel's options).
Finally, if you have a lot of data that you need to sort, and neither of the above methods is suitable, then you can always outsource the task to a professional data entry company. These companies have experienced staff who are very efficient at sorting large amounts of data quickly and accurately.
