    Default Unable to recognize OLE stream - Input Excel error

    Hello guys,

    I know that there is a older topic about this, but I want to know if is there a new solution?

    I extract almost 100 excel files in xls of my other system then I need to consolidate and transform this files.

    If I use the JXL engine the error is "Unable to recognize OLE stream", when I use the Apache POI, the error is " Invalid header signature; read 0x0010000000060409, expected 0xE11AB1A1E011CFD0"

    I wouldn't like to save it again in another extension.

    May anyone help me, please?

    So long, and thanks for all the fish.

    I googled this too, but isn't there a pentaho solution for this?

    Because the only solution that I found was to save the file again.
