If the number of rows having missing values is less, we can delete the rows.
Else we can impute it by using mean or median or mode of the column.
We can also use forward fill or backward fill where the missing cell will be substituted by the previous value and the next value respectively.
We can also use the column having the missing value as target feature and train a machine learning model using the remaining features to find out the missing values.
