title: How to create an editable excel
body: <p>I am creating an Excel file:</p>
  
  <pre><code>SpreadsheetDocument document = SpreadsheetDocument.Create(filename, SpreadsheetDocumentType.Workbook)
  WorkbookPart workBookPart = document.AddWorkbookPart();
              workBookPart.Workbook = new Workbook();
  
              WorksheetPart workSheetPart = workBookPart.AddNewPart&lt;WorksheetPart&gt;();
              workSheetPart.Worksheet = new Worksheet();
  
  
              Sheets sheets = workBookPart.Workbook.AppendChild(new Sheets());
  
              Sheet sheet = new Sheet()
              {
                  Id = workBookPart.GetIdOfPart(workSheetPart),
                  SheetId = 1,
                  Name = "Test Sheet"
              };
              sheets.Append(sheet);
  
              workBookPart.Workbook.Save();
  </code></pre>
  
  <p>When I open the file it's only ReadOnly, how I can make it editable to the user?</p>
  
  <p>ClosedXML is the priority, alternative way of the solution can be OpenXML</p>
