Writing API Results to CSV in Python

Question

I am looking for some assistance with writing API results to a .CSV file using Python. At this point, I'm successfully writing to .CSV, but I cannot seem to nail down the code behind the .CSV format I'm looking for, which is the standard one field = one column format.

Any help is appreciated! Details are below. Thanks!

My code:

import requests
import json
import csv

urlcomp = 'http://url_ommitted/api/reports/completion?status=COMPLETED&from=2016-06-01&to=2016-08-06'
headers = {'authorization': "Basic API Key Ommitted", 'accept': "application/json", 'accept': "text/csv"}

## API Call to retrieve report
rcomp = requests.get(urlcomp, headers=headers)

## API Results
data = rcomp.text

## Write API Results to CSV
with open('C:\_Python\\testCompletionReport.csv', "wb") as csvFile:
    writer = csv.writer(csvFile, delimiter=',')
    for line in data:
        writer.writerow(line)

The code above creates a .CSV with the correct output, but it's writing each character from the API results into a new cell in Column A of the output file. Screenshot below:

I've also attempted the code below, which writes the entire API result set into a single cell in the .CSV output file.

Code:

data = rcomp.text

with open('C:\_Python\\CompletionReportOutput.csv', 'wb') as csvFile:
    writer = csv.writer(csvFile, delimiter = ',')
    writer.writerow([data])

Output:

Below is a screenshot of some sample API result data returned from my call:

Example of what I'm looking for in the final .CSV output file:

EDIT - Sample API Response:

I think for the german version of excel (not sure) the separator is ; - possibly different for other languages. — janbrohl

Please add the actual API response directly into the question instead of a screenshot; nobody can test anything to help you. Does the API not send json in response which you're converting? At a glance, I don't see how you could reasonably separate out the newlines in the screenshot response and be sure that you have the correct data going into the correct columns, they're different lengths - surely the raw structure is more sensible? — roganjosh

@roganjosh I've added the csv/text API response. I'm assuming that is what you're looking for? Or do you need to see the response in JSON format? Thanks — jdgaub

I'm trying to copy/paste into txt but I can't replicate what I think is just \n split being added in data = rcomp.text. I think data = recomp.json() will make this much easier to split out :) — roganjosh

So, I eventually stumbled onto a solution. Not sure if this is the "correct" way of handling this, but the code below wrote the API results directly into a .CSV with the correct column formatting.

# Get JSON Data
rcomp = requests.get(urlcomp, headers=headers)

# Write to .CSV
f = open('C:\_Python\Two\\newfile.csv', "w")
f.write(rcomp.text)
f.close()

csvFile = open('C:\_Python\\CompletionReportOutput.csv', 'w')

writer = csv.writer(csvFile, delimiter = ' ')

for row in data.split('\n'):
    writer.writerow(row)

I doubt that this alone would solve the issue. You'd then need to split the row surely? Without the API response, I don't think you can answer this

This definitely moved it in the right direction. The fields are writing to the correct columns, but there are some spacing and " character issues. Output added to original question. Thanks!

Can you try and use writer.writerow(row.replace('"',''))
