invalid header - is it possible to ignore the error

[Gil Vernik <Gi...@solaredge.com>]

Hi there,

I am using  POI 3.2-Final.

 

Here is the problem : 

I am getting an xsl file from some URL. If I open this file with excel
directly from web, or save it to disk and then open it - Excel throws an
error that this file is not of excel  type and asks me "abort or
continue". Pressing continue - excel open the file and everything is
perfect and the file is displayed correctly.

There is probably some invalid header of this file, but forcing  Excel
to ignore it - solves the problem.

 

 

Now, I want the same behavior when I using POI. Currently POI throws an
exception, that invalid header signature is present. Is there a way (
without recompile POI ) to force him to continue even if the header
signature wrong? After all, the file is of excel type.

 

Thanks,

Gil.

Perhaps you can check whether the file is really an Excel file or an XML/HTML based file that’s renamed into .xls.
You may check by opening it with text editor.

Cheers,
