+# How to open a CSV file with a tab delimiter using XlsIO?
+
+Syncfusion XlsIO allows you to open CSV files with custom delimiters, including tab delimiters. When opening a CSV file, you can specify the delimiter character as the second parameter in the [Open](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorkbooks.html#Syncfusion_XlsIO_IWorkbooks_Open_System_String_Syncfusion_XlsIO_ExcelOpenType_) method.
+
+The following code example illustrates how to open a CSV file with a tab delimiter using XlsIO.
+
+{% tabs %}
+{% highlight c# tabtitle="C# [Cross-platform]" %}
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+ // Instantiate the Excel application object
+ IApplication application = excelEngine.Excel;
+
+ // Assign default application version
+ application.DefaultVersion = ExcelVersion.Xlsx;
+
+ // Open a CSV file with a tab delimiter ("\t")
+ IWorkbook workbook = application.Workbooks.Open(Path.GetFullPath(@"Data/InputTemplate.csv"), "\t");
+
+ // Access the first worksheet from the workbook
+ IWorksheet worksheet = workbook.Worksheets[0];
+
+ // Save the workbook to disk in XLSX format
+ workbook.SaveAs(Path.GetFullPath(@"Output/Output.xlsx"));
+}
+{% endhighlight %}
+
+{% highlight c# tabtitle="C# [Windows-specific]" %}
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+ // Instantiate the Excel application object
+ IApplication application = excelEngine.Excel;
+
+ // Assign default application version
+ application.DefaultVersion = ExcelVersion.Xlsx;
+
+ // Open a CSV file with a tab delimiter ("\t")
+ IWorkbook workbook = application.Workbooks.Open("InputTemplate.csv", "\t");
+
+ // Access the first worksheet from the workbook
+ IWorksheet worksheet = workbook.Worksheets[0];
+
+ // Save the workbook to disk in XLSX format
+ workbook.SaveAs("Output.xlsx");
+}
+{% endhighlight %}
+
+{% highlight vb.net tabtitle="VB.NET [Windows-specific]" %}
+Using excelEngine As New ExcelEngine()
+ ' Instantiate the Excel application object
+ Dim application As IApplication = excelEngine.Excel
+
+ ' Assign default application version
+ application.DefaultVersion = ExcelVersion.Xlsx
+
+ ' Open a CSV file with a tab delimiter ("\t")
+ Dim workbook As IWorkbook = application.Workbooks.Open("nputTemplate.csv", "\t")
+
+ ' Access the first worksheet from the workbook
+ Dim worksheet As IWorksheet = workbook.Worksheets(0)
+
+ ' Save the workbook to disk in XLSX format
+ workbook.SaveAs("Output.xlsx")
+End Using
+{% endhighlight %}
+{% endtabs %}
