Interact using XlsIO with a currently open Excel Workbook

Is XlsIO only used for reading, generating and creating Excel files that are currently closed or can it also interact with Excel workbooks that are currently open like Microsoft.Office.Interop.Excel?

I was hoping to see if XlsIO might offer some enhanced functionality or performance over Interop, but require it to interact with workbooks that are currently open, not previously saved/created files.

Hi Tttmack,


Thank you for using Syncfusion products.


Yes, we can interact with the currently opened excel workbook using OpenReadOnly method in XlsIO. We have provided a sample to achieve your requirement in the below link. Also you could use the below code snippet to interact with currently opened workbook.


Code Snippet:

IWorkbook workbook=application.Workbooks.OpenReadOnly(“Sample.Xlsx”);

Please let us know if you need any clarification.
