We have a lot of chemistry MCQs in an excel file with lot of chemistry formulas and equations. When we tried to import these MCQs into mySQL based database all subscripts used in formulas lost and taken as normal character e.g, H2SO4, CO2, CH3 etc and makes our formulas and elements name nonsense...
