Introduction
Named ranges let you give a name to a cell or group of cells. This makes it easier to use those cells in formulas and find them quickly. Instead of remembering cell addresses like A1 or B2:B10, you use a friendly name.
When you want to use a clear name in formulas instead of cell addresses, like TotalSales instead of B2:B10
When you have a large sheet and want to jump quickly to important cells or ranges
When you share a sheet and want others to understand formulas easily
When you want to protect or lock a specific range by name
When you create charts or reports that use the same data range repeatedly
