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.NumberDecimalSeparator and WorkbookSettings.NumberGroupSeparator properties to set the custom separators for formatting/parsing numbers.
The following screenshot shows the Advanced Excel Options and highlights the section to specify the Custom Separators.
