I'm having a problem generating my xlsx file.
It's a file with 22 worksheets with the size 394 KB. I try to add 5 more worksheets to it but it hangs. I try to .save() after each worksheet but the hangs only happen after i save the 3rd one.
I use the following code for creating the worksheets
string worksheet = "Presencas" + comeca.ToString("dd-MM-yyyy");
I don't know whats wrong.
