Whenever I try generating an excel report, the log file created in my computer's APPDATA folder shows the following error :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<recoveryLog xmlns=""><logFileName>error009480_01.xml</logFileName><summary>Errors were detected in file 'E:\fb\report\resources\g_Report.xlsx'</summary><additionalInfo><info>Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.</info></additionalInfo></recoveryLog>

How can I avoid this ?

This generally means there is some sort of corruption in the Excel file. Maybe, if you show the code you are using to generate the file, someone can suggest where the corruption is occurring.

This would suggest you are using some code that is incompatible with newer versions of Excel

this is the code for WORK BOOK..........

public static Workbook GetWorkbook(String _fileName)
var excel = new Application();
var workbook = excel.Workbooks.Open(_fileName, 1, true,
5, "",
"", true,
XlPlatform.xlWindows, "",
true, false,
0, false,
false, true);
excel.Visible = false;
return workbook;

........this where i m writng data

public byte[] GetRiskReportByte(IList riskList, RiskListHelper risklisthelper)
string fileName = null;
Workbook theWorkbook = null;
fileName = "_Report.xlsx";
theWorkbook =GetWorkbook(AppDomain.CurrentDomain.BaseDirectory + "\\" + "Report" + "\\" + "_Report.xlsx");
var worksheet = (Worksheet)theWorkbook.Sheets[1];
var worksheet2 = (Worksheet)theWorkbook.Sheets[2];
worksheet.Name = "xyzReport";
worksheet2.Name = "zzz";
worksheet.Cells[1, 1] = "Risk Name";

worksheet.Protect("abc@123$", false, true, false, true, false, false, false, false, false, false, false, false, false, false, false);
worksheet.Cells.Locked = false;

byte[] byteContent = ExportImportUtil.StreamFile(fileName);

theWorkbook.Close(false, fileName, true);
return byteContent;
Make sure you have the following at the end of your "response" logic:
