c# – How to set value of Excel cell by name instead of using coordinates with EPPlus?

Posted by: admin April 23, 2020 Leave a comment


I am able to set cell values using EPPlus:

var template = new FileInfo(Server.MapPath("~/App_Data/my_template.xlsx"));
var pck = new ExcelPackage(template);
var ws = pck.Workbook.Worksheets.First();
ws.Cells[15, 4].Value = 66; 
ws.Cells["B1"].Value = 55;

Instead of addressing the target cell by its coordinates I would like
to use a named cell/variable “profits”.

ws.Range("profits").Value = 66;

However, EPPlus does not support ws.Range(…).

=> Is it nevertheless possible to do so? How would I write an extension method that provides the wanted functionality?

var profits = pck.Workbook.Names["profits"];

Is there a way to get 'named' cells using EPPlus?

It is also possible to set the values for a named range:

var ws = pck.Workbook.Worksheets.First();
using (var namedRange = pck.Workbook.Names["MyNamedRange"])
        for (int rowIndex = namedRange.Start.Row; rowIndex <= namedRange.End.Row; rowIndex++)
          for (int columnIndex = namedRange.Start.Column; columnIndex <= namedRange.End.Column; columnIndex++)
            ws.Cells[rowIndex, columnIndex].Value = 66;
