Load and format a CSV file

[perfringo]

I don't fully understand objective but assuming that you have csv file named 'source-json.csv' with data on rows and want to have json one can simply do something along those lines:

import json
with open('source-json.csv', 'r') as f:
    d = {k: v.strip() for (k, v) in enumerate(f, start=1)}
    j = json.dumps(d)

One can write j to file or whatever:

Output:
{"1": "1231241231", "2": "1235135135", "3": "5457345345", "4": "4577865568", "5": "8654563848"}
