Read and Write External Connection of XLS and XLSB files

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 the same for all types of formats.

Read and Write External Connection of XLS/XLSB file

The following sample code loads the sample XLSB file (XLS can also be loaded) 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 XLS/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

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