How to map column

Hi I have a csv file in a data lake (Source) with no column mapping, the respective column mapping is in a different json file. I need to copy this csv file from source to my own data lake but with the correct mapping of column , ie all the columns are named correctly. I cannot mannually map them since the csv files has 300 + column.  How do i do this with the help of ADF pipeline. 

Source - CSV file column is in this format, need this corrected with the correct mapping from json file
