 # CSV to Excel Conversion
 
-XlsIO supports converting CSV data to Excel files by saving the workbook using the [SaveAs](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorkbook.html#Syncfusion_XlsIO_IWorkbook_SaveAs_System_IO_Stream_) method. When opening a CSV file, users can specify various delimiters to structure the data appropriately.
+XlsIO can read a CSV file with [`IWorkbooks.Open`](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorkbooks.html#Syncfusion_XlsIO_IWorkbooks_Open_System_String_System_String_) and write the result to an Excel workbook with [`IWorkbook.SaveAs`](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorkbook.html#Syncfusion_XlsIO_IWorkbook_SaveAs_System_String_). The default delimiter when opening a CSV is a comma (`,`). To read other delimited formats, pass the matching character to the `Open` overload.
