We have created a free tool to convert BigCommerce data into Shopify-compatible format.<\/p>\r\n

You can use this tool to convert your product, customer, and order data into files that are ready to import into Shopify.<\/p>\r\n

Once converted, you can simply upload the new data files to Shopify.<\/p>\r\n

Please see the code and complete guide below.<\/p>\r\n

Step 1 \u2014 Install Python (one-time setup)<\/strong><\/h4>\r\n\r\n\r\n\r\n

Python is the free program that runs the script. If you already have Python installed, skip to Step 2.<\/p>\r\n\r\n\r\n\r\n

    \r\n
  1. \r\n
      \r\n
    1. 1. Go to python.org\/downloads in your web browser.<\/li>\r\n
    2. 2. Click the yellow \u201cDownload Python\u201d button.<\/li>\r\n
    3. 3. Open the downloaded file and run the installer.<\/li>\r\n<\/ol>\r\n<\/li>\r\n<\/ol>\r\n

      Important<\/strong>
      On the first install screen, tick the box that says
      \u201cAdd Python to PATH\u201d<\/strong> before clicking Install.<\/p>\r\n

        \r\n
      1. 4. Click Install Now and wait for it to finish.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n

        To check it worked, open your terminal (Command Prompt on Windows, Terminal on Mac) and type:<\/p>\r\n\r\n\r\n\r\n

        python --version<\/code><\/pre>\r\n\r\n\r\n\r\n
        If you see a version number like \u201cPython 3.12.0\u201d, you are ready for Step 2.<\/p>\r\n\r\n\r\n\r\n
        Step 2 \u2014 Install the Required Add-ons<\/strong><\/h4>\r\n\r\n\r\n\r\n
        The script needs two free add-on packages to read Excel\/CSV files. Open your terminal and type this single line:<\/p>\r\n\r\n\r\n\r\n
        pip install pandas openpyxl<\/code><\/pre>\r\n\r\n\r\n\r\n
        Press Enter and wait a few seconds for it to finish. You only need to do this once.<\/p>\r\n\r\n\r\n\r\n
        Step 3 \u2014 Save Your Files in One Folder<\/strong><\/h4>\r\n\r\n\r\n\r\n
        Download the python script bc_to_shopify_converter.py<\/em>\u00a0from GitHub using this link : Download Python Script<\/strong><\/a><\/p>\r\n
        Create a new folder on your Desktop (for example, \u201cBC-to-Shopify\u201d). Inside it, create another folder called \u201cinput\u201d – this is where all your BigCommerce export files will go.<\/p>\r\n\r\n\r\n\r\n
        Your folder structure should look like this:<\/p>\r\n\r\n\r\n\r\n
        BC-to-Shopify\/\r\n  bc_to_shopify_converter.py\r\n  input\/\r\n    bc_products.csv\r\n    bc_customers.csv\r\n    bc_orders.csv<\/code><\/pre>\r\n\r\n\r\n\r\n
        Place the script file directly inside \u201cBC-to-Shopify\u201d, and place your BigCommerce CSV exports inside the \u201cinput\u201d folder:<\/p>\r\n\r\n\r\n\r\n
