Hi,
Thank you for your inquiry.
I did an initial test using the latest version(Spire.XLS Pack(Hotfix) Version:12.5.3), but didn't reproduce your problem. I suggest you give the latest one a try. Also, I will attach my test code for your reference. If the problem still exist, please provide the following information for further investigation.
1) Your test code.
2) Test environment, such as win10, 64bit.
3) Application type, such as Console App, .NET Framework 4.8.
- Code: Select all
Workbook wb = new Workbook();
Worksheet sheet = wb.ActiveSheet;
string[,] array = new string[1, 1];
array[0, 0] = "1.1.1";
sheet.InsertArray(array, 1, 1, false);
wb.SaveToFile("output.xlsx");
Sincerely,
Kylie
