2. Save Workbook as CSV

Easy as that!

Here is the code for this little project. This code loads an existing Excel Workbook, and then simply saves it in the CSV format by using the SaveAsCsv method.

The Normal Excel workbook contains the following data:

// Import the IronXL library
using IronXL;

class Program
{
    static void Main()
    {
        // Load an existing workbook
        WorkBook wb = WorkBook.Load("Normal_Excel_File.xlsx"); // You can import .xls, .csv, or .tsv files

        // Save the workbook to a CSV file. This will save the first worksheet as a CSV.
        wb.SaveAsCsv("SaveAsCSV.csv", ","); // This will output: SaveAsCSV.Sheet1.csv
    }
}

// Import the IronXL library
using IronXL;

class Program
{
    static void Main()
    {
        // Load an existing workbook
        WorkBook wb = WorkBook.Load("Normal_Excel_File.xlsx"); // You can import .xls, .csv, or .tsv files

        // Save the workbook to a CSV file. This will save the first worksheet as a CSV.
        wb.SaveAsCsv("SaveAsCSV.csv", ","); // This will output: SaveAsCSV.Sheet1.csv
    }
}

' Import the IronXL library
Imports IronXL

Friend Class Program
	Shared Sub Main()
		' Load an existing workbook
		Dim wb As WorkBook = WorkBook.Load("Normal_Excel_File.xlsx") ' You can import .xls, .csv, or .tsv files

		' Save the workbook to a CSV file. This will save the first worksheet as a CSV.
		wb.SaveAsCsv("SaveAsCSV.csv", ",") ' This will output: SaveAsCSV.Sheet1.csv
	End Sub
End Class
