Failed to load excel file with spring + apache-poi
When I try to download an excel file ( .xls
/ .xlsx
) I get the following exception:
org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)

Does anyone suggest me if something is missing that is causing the exception to be exceeded?

As suggested by @Luke I made the following change in my code to accommodate both versions of the excel file xls
andxlsx
Workbook offices;
String lowerCaseFileName = file.getOriginalFilename().toLowerCase();
if (lowerCaseFileName.endsWith(".xlsx")) {
offices = new XSSFWorkbook(file.getInputStream());
} else {
offices = new HSSFWorkbook(file.getInputStream());
}
Since I am checking the file type before the above code. Thus, there will be only two scenarios: .xls
or .xlsx
. Also, I have included the following libraries to make it work
In the hope that it will save someone.
