Hi, i have tried below code .. i wanted to group and sum the values but its not grouping at all. Pls find my code below
var groupp=from k in excelFile.Worksheet(sheetName).ToList() select k;
var grouped = from row in groupp group row by row["Issue Type"] into g select new { edd = g.Key, c = g.Sum(row => Convert.ToDouble(row["Time Spent"])) };
foreach (var groupe in grouped)
MessageBox.Show("key is" + groupe.edd + " : count=" + groupe.c);

I strongly recommend you to download this tutorial: 101 LINQ Samples[^] and read this article: Using LINQ to Query Tables in Excel 2007[^] then you'll be able to create proper linq statement. Try!
