by Chaknith Bin

IronXL is a powerful tool in Excel that facilitates math aggregation functions such as Average, Sum, Min, and Max. These functions are essential for performing calculations and analyzing data. With IronXL, you can harness the capabilities of these math functions to derive insights, make informed decisions, and effectively analyze numerical data in Excel without the use of Interop.

How to Use Math Function

  1. Download the C# library for utilizing aggregate functions
  2. Load an existing Excel file
  3. Select the desired range, row, or column to aggregate
  4. Invoke the available math functions such as Sum, Avg, Min, or Max
  5. Perform further calculations based on the result

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.

Please note
Non-numerical values will not be included in the calculation.

WorkBook workBook = WorkBook.Load("sample.xls");
WorkSheet workSheet = workBook.WorkSheets.First();

// Get range from worksheet
var range = workSheet["A1:A8"];

// Calculate the sum of numeric cells within the range
decimal sum = range.Sum();

// Calculate the average value of numeric cells within the range
decimal avg = range.Avg();

// Identify the maximum value among numeric cells within the range
decimal max = range.Max();

// Identify the minimum value among numeric cells within the range
decimal min = range.Min();
