No Worksheets found

EDIT : After further investigation, the problem was not EPPlus related. My apologies for wasting your time.


I am currently facing a weird issue while trying to manipulate an Excel file with EPPlus.
I have a file that I was provided which I managed to succesfully access and read. However, when I open this file with Excel on my computer and then save it, EPPlus does not find Worksheets in the document anymore.

Here is how I manipulate the file :
public static void ImportFile(string filePath) {
            var existingFile = new FileInfo(filePath);

            using (var package = new ExcelPackage(existingFile)) {
                ExcelWorkbook workBook = package.Workbook;
                if (workBook != null) {
                    if (workBook.Worksheets.Count > 0) {
                        ExcelWorksheet currentWorksheet = workBook.Worksheets.First();


The if statement is successful when I import the file untouched (workBook.Worksheets.Count = 2) and I can manipulate the data.
After opening the Excel file and saving it again without touching data, workBook.Worksheets.Count = 0 which prevents me going further.

I am working on Windows 7 64bit, using the version of EPPlus and the Office365 version of Excel 2013.

If someone has already faced a similar problem, any help would be much appreciated.

My bad, the problem was located before trying to read the file. My uploader did not save the file properly which caused the emply worksheet list when reading a non existing file.

This topic can therefore be closed.
