How to Get names of Excel worksheets

Hello, I’m a beginner.
I have an Excel Workbook with many worksheets.
In my Excel Workbook, there are over 50 Worksheets.
I want to make PDF files from some worksheets(1 Worksheet to 1 PDF file) by robots.
Names of PDF files are from names of worksheets.

I think as follows:
(1) Use Excel Application Scope to my Excel Workbook
(2) Assign Output of (1) to variable1(UiPath.Excel.WorkbookApplecation)
(3) To get All Worksheets, use GetWorkSheets function, like “variable1.GetSheets”.

Then Error occurred “Exception from HRESULT: 0x80004002 (E_NOINTERFACE)”.
Message is “Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘Microsoft.Office.Interop.Excel.Worksheet’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{000208D8-0000-0000-C000-000000000046}’ failed due to the following error: Exception from HRESULT: 0x80004002 (E_NOINTERFACE)”.

Samples and my robot are correct.
But they do not work for my Excel workbook.
There is 1 Graph Sheet in my Excel workbook.
My robot works well for Table worksheets, but cannot work for a Graph worksheet.
