Aggregate Functions Example
When working with ranges of cells in an Excel spreadsheet, you can utilize various aggregate functions to perform calculations. Here are some essential methods:
- The
Sum()method calculates the total sum of the selected range of cells. - The
Avg()method determines the average value of the selected range of cells. - The
Min()method identifies the minimum number within the selected range of cells. - The
Max()method finds the maximum number within the selected range of cells.
These functions are valuable tools for analyzing data and deriving meaningful insights from your Excel spreadsheets.

// Identify the minimum value among all numeric cells within the specified range
// The Min extension method returns the smallest value among the numeric cells.
