I am trying to convert html table to excel.
string contents = "<html><body><h1>hello</h1></body></html>";
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
MemoryStream stream = new MemoryStream(byteArray);
Workbook workbook = new Workbook();
workbook.LoadFromStream(stream);
//AutoFit rows
Worksheet sheet = workbook.Worksheets[0];
sheet.AllocatedRange.AutoFitRows();
//Save the document to file
workbook.SaveToFile("Result.xlsx", FileFormat.Version2010);[/list][/list]
The code " workbook.LoadFromStream(stream);" throws this exception. 'Zip exception.Can't locate end of central directory record. Possible wrong file format or archive is corrupt.'
Please help.
Hello,
Thanks for your inquiry.
I have tested the code you provided using the latest version of Spire.XLS (Spire.XLS Pack(Hotfix) Version:13.11.4), but I was unable to reproduce the issue you mentioned. Could you please confirm if you have also tested it with the latest version?
In case you haven't, I recommend trying the code with the latest version as a first step. Additionally, you can modify the line "workbook.LoadFromStream(stream);" to "workbook.LoadFromHtml(stream);" and see if the issue persists.
If the issue still exist after these tests, please provide the following information. Thank you in advance.
1) Your test environment, such as OS info (E.g. Windows 10, 64-bit) and region setting (E.g. China, Chinese).
2) Your application type, such as Console app (. Net Framework 4.5).
Sincerely,
Annika

Thnaks for ur reply. It worked when I upgraded to new version. Tat html was the sample one I tested.
String content = @"<!DOCTYPE html><html><head> <title></ title ></ head >< body > < table class='table table-striped dataTable' border='1' style='Width:1575px'> <tr> <td colspan = '21' align='center'>Nov-2023</td> </tr> <tr border = '0' > < td colspan='3' align='center'>Monday</td> <td colspan = '3' align='center'>Tuesday</td> <td colspan = '3' align='center'>Wednesday</td> <td colspan = '3' align='center'>Thursday</td> <td colspan = '3' align='center'>Friday</td> <td colspan = '3' align='center'>Saturday</td> </tr> </table></body></html>";
The above html is just one part of my actual html. It throws "Input string is not in correct format" error. Please help
