This is a formatter to take data from Turn14.com's product data CSV export and import it to a google sheet that is formatted for Shopify's CSV import process. I made this before Turn14.com released their REST API, but I feel this is still useful to those who do not have experience with APIs.

1. GSpread
2. oauth2client

Simply run the following command:

pip install -r requirements.txt

Go to Turn14, go to data, and download Product Data Loadsheet. Unzip the file into your working folder.

Use the following as a template for your Google Sheet: Shopify Import Template

This script uses the gspread package to work with Google sheets. Be sure to include "client_secret.json" in your working directory.
If you're unsure on how to get your client_secret.json, please follow this tutorial completely: Using OAuth2 for Authorization
Rename your credentials file to client_secret.json, as that's how this script retreives the file.
Your client_secret.json will look like the following:

{
  "type": "service_account",
  "project_id": "your project id",
  "private_key_id": "your private key id",
  "private_key": "-----BEGIN PRIVATE KEY-----PRIVATE KEY HERE-----END PRIVATE KEY-----\n",
  "client_email": "your client email",
  "client_id": "your client id",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "your cert url"
}

What you're going to need to do is take your "client_meail": "your client email" and share your Google Sheet with this user, giving them editing rights. If you do not do this, you will not have access to your sheet.
