Hi All,
My question is very simple and I guess I know the answer.
Is is possible to modify an excel file already opened via Aspose ?
Like changing a value, update a chart …

Thanks,
Hadrien

@hormancey,

Reading an Excel file (even if it is being used in some process or is opened in MS Excel) via Aspose.Cells is not a problem, you can do that. But when you modify contents and then re-save the Excel file with the same name (while you have already opened it in MS Excel or you are using the file in some other process), it is not allowed.

You cannot overwrite/re-save an Excel file with the same name using Aspose.Cells APIs if you have already opened the Excel file into MS Excel manually. You either need to close the file in MS Excel or save it as with some other name by Aspose.Cells APIs (you cannot use the same name if the file is already in some process or opened into MS Excel).
