Add document to Spreadsheet via OLE Leave feedback

The OLE technology provided by Microsoft allows to insert some other document content into the cell that is previosly selected by RowIndex and ColumnIndex of the currently editing Excel spreadsheet. For example, the PDF document can be inserted in the Excel spreadsheet document as image link inside of predefined cell as was presented in the example below.

GroupDocs.Merger provides an ability to add other single document as embedded document to Presentation. 
Here are the steps for it:

• Initialise OleSpreadsheetOptions class with embedded file path and page number;
• Instantiate Merger object with source document path or stream;
• Call ImportDocument method and pass OleSpreadsheetOptions object to it;
• Call Save method and pass desired file path to save resultant document.

The following code sample demonstrates how to add other single document as embedded document to Excel spreadsheet:

string filePath = @"c:\sample.xlsx";
string filePathEmbedded = @"c:\embedded.pdf";
string filePathOut = @"c:\output\result.xlsx";

int pageNumber = 2;
OleSpreadsheetOptions oleSpreadsheetOptions = new OleSpreadsheetOptions(filePathEmbedded, pageNumber);
oleSpreadsheetOptions.RowIndex = 2;
oleSpreadsheetOptions.ColumnIndex = 2;

using (Merger merger = new Merger(filePath))
{
    merger.ImportDocument(oleSpreadsheetOptions);
    merger.Save(filePathOut);
}
