How to disable the thousand or comma separator for the decimal numbers when exporting the dataset to an Excel File?
RESOLUTION 1
When choosing export format as "Excel File", select the 'Use only "General" cell formatting' to remove the thousand separator from the generated file.
RESOLUTION 2
Instead of choosing "Excel File" export format, select "Excel Instance". You will then have to save the file manually from Excel.
** Note RESOLUTION 1 does not apply in version 12.8 as the 'Use only "General" cell formatting' option has been removed, in error. This will be re-introduced in version 12.9
