For finance professionals working in Transactional Services or Investment Banking, building models with tons of formulas, tables and sheets is the norm. However, the more comments, formulas, conditional formatting and hidden sheets you add, the heavier the Excel file gets. You can easily discover which sheets are the heaviest in your Excel file. To do so, make a copy of your Excel file and follow these steps:
Spotting the heaviest Excel sheets can help you choose which one to start with. For instance, “sheet26.xml” accounts for almost one-third of the global volume. Usually, it corresponds to the n+1 sheet in your Excel file. So, in the above example, we could start by trimming the twenty-seventh sheet. Be careful! The n+1 rule takes into account hidden sheets. If you have a lot of hidden sheets, it can become tricky to find the right one. One way to know for certain you have the right sheet is to get the exact name. Here is the detailed guide for finding a sheet’s name. Now, it’s time to dive into our seven tips for reducing an Excel file size: Tip #1: Remove conditional formattingConditional formatting comes in handy when you need to highlight specific data.
