Start by accessing the data you need from Whisky Hunter. If the data is available via a web interface, use a web browser to navigate to the specific section where the data is displayed. If Whisky Hunter provides the option to export data, use this feature to download the data in a supported format such as CSV or JSON.

Set up a local environment on your computer to store the Whisky Hunter data temporarily. Create a new directory to organize your files, ensuring you have enough storage space. Save any exported files here, or copy and paste the data into a new file if needed.

Open the data files using a text editor or spreadsheet software, such as Microsoft Excel or Google Sheets. Ensure the data is clean and consistent, checking for missing values, incorrect data types, and formatting issues. Save the file in a structured format like CSV or JSON, which is easily readable by most programming languages.

Set up your development environment by installing any necessary programming tools. For this task, you'll need a programming language that supports HTTP requests and data manipulation, such as Python. Ensure you have the latest version of Python installed along with necessary libraries like `requests` and `pandas` for data handling.

Create a script using your chosen programming language to read the prepared data file. Transform the data into a format compatible with Convex's requirements. This might involve converting data types, renaming fields, or reformatting records. Test the script to ensure it accurately processes the data without errors.

Utilize Convex's API to upload the transformed data. Refer to Convex's API documentation to understand the endpoint requirements for data insertion. Use the `requests` library in Python to send HTTP POST requests with the transformed data to Convex. Ensure proper authentication and error handling is in place within your script.

Once the data has been uploaded to Convex, verify the integrity of the data. Access Convex's web interface or use their API to fetch and inspect a sample of the uploaded data. Check for any discrepancies or errors in the data upload process and make necessary adjustments to your script if issues are found. Repeat the upload process if needed, until the data is accurately reflected in Convex.

By following these steps, you can successfully transfer data from Whisky Hunter to Convex without the need for third-party connectors or integrations.
