[FEATURE] Convert csv file to json

The developer should use react js to write a function that will convert a .csv file format to json.

The converted output should have the following format
```
{
"transaction_id":[1,2,3,4],
"unique_borrower_id":[1,2,3,4],
"date_of_transaction":["2020-02-09","2020-02-13", "2020-03-24", "2019-12-14"],
"details_of_transaction":["Airtime_purchase", "customer_transfer", "deposit_funds", "Msuary_loan_disbursement"],
"transaction_status":["completed", "other_status"],
"amount_transacted":[340, 34349, 6568, 790]
}
```
