Thousand Separator and Decimal Separator

Hi!!!

 

I write from Spain. I need to publish excel worksheet in my dashboard. When I upload the worksheet as a report, the Thousand Separator and Decimal Separator are ok (for example., 1.842,50). But when I publlished it in my dashboard, it changes Thousand Separator by comma and Decimal Separator by point (for example., 1,842.50).

 

Is there any solution?

 

Thank you very much in advance!
