Specify Custom Number Decimal and Group Separators for Workbook

In Microsoft Excel, you can specify the Custom Decimal and Thousands Separators instead of using System Separators from the Advanced Excel Options as shown in the screenshot below.

Aspose.Cells provides the WorkbookSettings.setNumberDecimalSeparator() and WorkbookSettings.setNumberGroupSeparator() properties to set the custom separators for formatting/parsing numbers.
