Link Excel Worksheet in a Word document

Question

What I wanted to achieve :

Implement a function in C# which executes similar to the Word object insertion as a link and attach a selected excel file into the word document with 'link to file', so that the changes to the excel source file is reflected in the Word document).

Word Insert > Object( in Text button group) > Create from File

What I tried :

I am using Office 365.

Get the UsedRange.AddressLocal from a selected worksheet of the excel file, and get cell range from it. Then use the Word.Range.PasteSpecial method.

string addressLocal = worksheet.UsedRange.AddressLocal;  
if (addressLocal.Length > 0)  
{  
   cellRange = addressLocal.Replace("$", "");           
}  
Excel.Range range = this.worksheet.Range[cellRange];  
range.Copy();

Get the range of the current selection.

wordRange = wordApp.Selection.Range;

Paste the copied range to the Word document.

wordRange.PasteSpecial(  
     Link: true,  
     DataType: Word.WdPasteDataType.wdPasteOLEObject,  
     Placement: Word.WdOLEPlacement.wdInLine,  
     DisplayAsIcon: false  
);

But this gives an error when we try double click on the inserted excel.

I have went through many articles in web related to this error, but none of them fixed my issue.

But when I change the copying excel cell range as below and pasting it doesn't give errors when double click and open the inserted excel.

string addressLocal = worksheet.UsedRange.AddressLocal;  
if (addressLocal.Length > 0)  
{  
    cellRange = addressLocal.Replace("$", "");  
    // If cellRange is "A1:E6", below code make it as "A1:E5"  
    string a = cellRange.Substring(0, cellRange.Length - 1);  
    int b = int.Parse(cellRange.Substring(cellRange.Length - 1, 1)) - 1;  
    cellRange  = a+ b.ToString();  
}  
Excel.Range range = this.worksheet.Range[cellRange];  
range.Copy();

Is my approach for implementing the linking excel to word is incorrect? If so, could anybody please let me know what should I do to implement some functionality similar to word Excel object linking?

If my approach is correct, what should I do to insert the exact used range of the excel worksheet to the word?

Please help me with this.

Thank you in advance.

Hi ApsSanj-3718,
You can try to use Range.PasteExcelTable method to embed an excel-file in a word document.
Here is my test code you can refer to.

using Excel = Microsoft.Office.Interop.Excel;  
using Microsoft.Office.Interop.Word;  
using Application = Microsoft.Office.Interop.Word.Application;  
  
var path =  @"C:\Users\Desktop	t.xlsx";           
Excel._Application excel = new Excel.Application();  
var template = excel.Workbooks.Add(path);  
var worksheet = (Excel.Worksheet)template.Worksheets["Sheet1"];  
var table = (Excel.Range)worksheet.Range["A1:A5"];  
table.Copy();  
Application ap = new Application();  
Document document = ap.Documents.Open(@"C:\Users\Desktop	t.docx");  
document.Bookmarks["test"].Range.PasteExcelTable(false, true, false);
