Hello, I stay in India. I was using Windows 7 and Office 2010. In the regional settings in Windows 7, I had selected "English (India)" and therefore, Excel 2010 was putting the thousands' separator as per the Indian Rules. In Windows 8 also, I've selected "English (India)" in my regional settings, but Excel 2013 is not putting the thousands' separator properly. Here is how it is putting it: 1234,56,789. It should have put it this way: 12,34,56,789. Please help.
