Hey I am using ExcelFormat Library for reading the xls file.

I have created the (.xls)Excel with external library function(libxlsxwriter) in c++ language.

What I Encountered is that the file created cannot be read back unless it is saved as with other name.



How to solve this error.?

Why is the value zero at the first time?

What I have tried:

BasicExcel e ;
bool value = e.load("sample.xls");

Here the value is always return 0 ,since the load operation is not happening.


but when I do "SaveAs" sample.xls manually value will be 1.
