Excel Password in Opening the File

Aspose.Cells Product Family
#1

Hi,

Is there a possibility of setting the excel password in opening the file so that it will prompt the user.Right now there is a option of ProtectionType.MODIFY_FILE but the problem is it has a read only Option while prompting the user.

Could you please tell me,is it possible to protect the file without any readonly option granted.

Regards

Joe

Hi Joe,

Thanks for considering Aspose.

For java version of Aspose.Cells, you may use ProtectionType.OPEN_FILE option and for .NET version you may utilize Workbook.Password property.

May the following code help you for your need, kindly consult it.

i).(java) Workbook workbook = new Workbook();
workbook.protectFile(ProtectionType.OPEN_FILE,"009");
workbook.save("e:\\Files\\testprotect.xls");


ii).(C#) Workbook workbook = new Workbook();
workbook.Password = "1234";
workbook.Worksheets[0].Cells["A1"].PutValue("Hello World!");
workbook.Save("e:\\Files\\protectionfiletest.xls");

Thank you.

Hi,

Thanks for the reply.But the exception that i am getting is this.

Exception in thread "main" com.aspose.cells.CellsException: Unsupports to set the opening file password.

at com.aspose.cells.r.a(Unknown Source)

at com.aspose.cells.Workbook.protectFile(Unknown Source)

at com.source.TestAspose.main(TestAspose.java:18)

When i try to set the password to the workbook it doesn't allow for it.Could you please give some highlight on it.I am using the Java version.

Hi Joe,

And to check the version no (which version you are using) at runtime you may use the api a line of code in your class as well.

E.g.,

System.out.println(CellsHelper.getReleaseVersion());

Thank you.
