My sample CSV file is :
firstName,lastName,email,phoneNumber
John,Doe,[email protected],0123456789
Jane,Doe,[email protected],9876543210
James,Bond,[email protected],0612345678
When i am executing this code the output is :
[{"firstName":"John","lastName":"Doe","email":"[email protected]","phoneNumber":"0123456789"},{"firstName":"Jane","lastName":"Doe","email":"[email protected]","phoneNumber":"9876543210"},{"firstName":"James","lastName":"Bond","email":"[email protected]","phoneNumber":"0612345678"}]
But I want the output should be:
[{"firstName":"lastName":"email":"phoneNumber"},
{"John":"Doe":"[email protected]":"0123456789"},
{"Jane":"Doe":"[email protected]":"9876543210"}]
Any help on this? regarding changes of code.
