Read and Write External Connection of XLSB or XLS file

Possible Usage Scenarios

Aspose.Cells already supports read and write external connection of XLSX file but now, it also supports this feature for XLSB and XLS file. However, the code is same for both types of format.

Read and Write External Connection of XLSB/XLS file

The following sample code loads the sample XLSB(XLS can also be loaded) file and reads its first External Connection which is actually a Microsoft Access DB Connection. It then modifies the DBConnection.Name property and saves it as output XLSB file. The screenshot shows the effect of code on sample XLSB file and output XLSB file after its execution. Please also see the console output of the sample code given below for a reference.

Sample Code

Following code shall work for both XLSB and XLS by loading and saving files with appropriate extension.
