How to Read Excel Files in C# using IronXL

In this tutorial, we delve into reading Excel files in C# using the IronXL library, which is free for development use. We begin by installing the IronXL package through the package manager console. First, add the namespace 'using IronXL' to your code. Next, load the desired Excel workbook with the 'Workbook.Load' method, specifying the file path and name. Once loaded, you can select the worksheet using 'Workbook.GetWorksheet'. A loop is employed to read data from cells A1 to A10, displaying the values in the console. Additionally, the tutorial demonstrates using aggregate functions to calculate sum and max values from the data range using LINQ. The tutorial concludes by highlighting that similar methods can be employed for other aggregate functions like min and average. For further assistance, the support team is available to help users facing any challenges.

Code Example

In the above code:

• We load an Excel workbook using WorkBook.Load by specifying the path to the file.
• We access the first worksheet using workbook.WorkSheets.First().
• A loop is used to iterate over cells A1 through A10 to print their values to the console.
• The LINQ queries are used to calculate the sum and maximum value in the range A1 to A10.
