Hi,
I convert the attached spreadsheetML to xlsx format using the code below. Then I open the document in Excel, do nothing, close it and then the popup appears that there are unsaved changes asking me if I want to save it.
var loadOptions = new LoadOptions( LoadFormat.SpreadsheetML );
var workbook;
using ( var stream = new FileStream( path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite ) )
{
workbook = new Workbook( stream, loadOptions);
}
var saveOptions = new XlsSaveOptions( SaveFormat.Xlsx );
_workbook.Save( outputPath, saveOptions );
Could you please tell me what could cause this?
Please find the spreadsheetML attached.
