+
+Yes. XlsIO supports converting an XLSB file to XLSX; however, the conversion is limited to cell values and cell styles.
+
+The example below shows how to convert an XLSB file to an XLSX file.
+
+{% tabs %}
+{% highlight c# tabtitle="C# [Cross-platform]" %}
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+ IApplication application = excelEngine.Excel;
+ application.DefaultVersion = ExcelVersion.Xlsx;
+
+ //Open an existing XLSB file
+ IWorkbook workbook = application.Workbooks.Open("Sample.xlsb");
+
+ //Save the file as XLSX
+ workbook.SaveAs("Output.xlsx");
+}
+{% endhighlight %}
+
+{% highlight c# tabtitle="C# [Windows-specific]" %}
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+ IApplication application = excelEngine.Excel;
+ application.DefaultVersion = ExcelVersion.Xlsx;
+
+ //Open an existing XLSB file
+ IWorkbook workbook = application.Workbooks.Open("Sample.xlsb");
+
+ //Save the file as XLSX
+ workbook.SaveAs("Output.xlsx");
+}
+{% endhighlight %}
+
+{% highlight vb.net tabtitle="VB.NET [Windows-specific]" %}
+Using excelEngine As New ExcelEngine()
+ Dim application As IApplication = excelEngine.Excel
+ application.DefaultVersion = ExcelVersion.Xlsx
+
+ ' Open an existing XLSB file
+ Dim workbook As IWorkbook = application.Workbooks.Open("Sample.xlsb")
+
+ ' Save the file as XLSX
+ workbook.SaveAs("Output.xlsx")
+End Using
