In Google Sheet, select a cell having at least 6 digits number in it, then go to Format > Number > Custom number format > (fill the inbox by [>9999999]##,##,##,##0;[>99999]##,##,##0;##,##0 ) and hit Apply.
If the entered number is 195665 then it was showing Indian format lakhs and crores as 1,95,665 but now it shows 195,665. See this.
Is there any other number format, which still works in Google sheet ? (It should not be formula like this answer, but it should be just a number formatting).
