 Microsoft Excel is known for its flexibility and power in managing data and performing complex calculations. However, when working with large spreadsheets, formulas can become confusing — especially when they include long cell references like =SUM(A2:A100) . That’s where Named Ranges come in. By assigning names to cell ranges, constants, or formulas, you make your worksheets easier to read, understand, and maintain. In this blog, we’ll explore what named ranges are, how to create them, and how to use them effectively in Excel formulas. 🔹 What Is a Named Range? A Named Range is a descriptive name assigned to a specific cell or range of cells in Excel. Instead of referring to a cell by its coordinates (like A1:A10 ), you can use a name (like SalesData ). For example: Instead of writing: =SUM(A2:A10) You can write: = SUM (SalesData) This makes your formulas much easier to read and understand — especially when sharing workbooks with others. 🔹 Why Use Named Ranges? N...

 Microsoft Excel is a versatile tool for managing and analyzing data. When you want to make data entry faster, more accurate, and consistent, Drop-Down Lists are an excellent feature to use.
