Con Aspose.Cells for Python via .NET è semplice aprire i file, ad esempio, per recuperare dati o usare un modello design per accelerare il processo di sviluppo.
Come aprire un file Excel tramite un percorso
Gli sviluppatori possono aprire un file Microsoft Excel usando il percorso del file sul computer locale specificandolo nel costruttore della classe Workbook. Basta passare il percorso nel costruttore come stringa. Aspose.Cells for Python via .NET rileverà automaticamente il tipo di formato del file.

| # The path to the documents directory. | |
| dataDir = RunExamples.GetDataDir(".") | |
| # Opening through Path | |
| # Creating a Workbook object and opening an Excel file using its file path | |
| workbook1 = Workbook(dataDir + "Book1.xlsx") | |
| print("Workbook opened using path successfully!") |
Come aprire un file Excel tramite uno stream
È anche semplice aprire un file Excel come uno stream. Per farlo, utilizzare una versione sovraccaricata del costruttore che prende l’oggetto Stream che contiene il file.

| dataDir = RunExamples.GetDataDir(".") | |
| # Opening through Stream | |
| # Create a Stream object | |
| fstream = open(dataDir + "Book2.xls", "rb") | |
| # Creating a Workbook object, open the file from a Stream object | |
| # That contains the content of file and it should support seeking | |
| workbook2 = Workbook(fstream) | |
| print("Workbook opened using stream successfully!") | |
| fstream.close() |
Come aprire un file con solo dati
Per aprire un file solo con i dati, utilizza le classi LoadOptions e LoadFilter per impostare l’attributo correlato e le opzioni delle classi per il file modello da caricare.
