Czy ktoś może mi powiedzieć, co robię, co jest nielegalne w programie Excel? Myślę, że excel sprawia, że SharedStrings przy jego naprawianiu. Nigdy nie pracowałem z SharedStrings i mam nadzieję, że nie będę musiał.
Możesz spróbować pobrać OpenXMLSDKToolV25.msi z http://www.microsoft.com/en-us/download/details.aspx?id=30425 jeśli załadować wygenerowany plik na produktywność Narzędzie w wielu przypadkach może ci powiedzieć, co jest nielegalne w wygenerowanym pliku. –
