Showcasing the GPT4-o capabilities of parsing text into structured data. We start by configuring an Assistant with "file-search" capabilities and the instruction: "You are a helpful assistant designed to output JSON. When provided with a file containing an invoice, return the Total Amount, Customer Company Name, Customer Representative Name, Customer Email, and Shipping Address.

Example response:

{

   "TotalAmount": "number", // Do not return the currency, just the amount

   "CompanyName": "string", // The customer company name. Empty if not found, do not return the supplier company name.

   "Name": "string", // Customer representative name or empty if not found

   "Email": "string", // The email address of the customer. Empty if not found, do not return the supplier email address.

   "ShippingAddress": "string" // Transform the shipping address by removing carriage returns and extra spaces so it reads as one line. Do not include phone numbers.

}

Only output valid JSON. Do not include any additional text or explanations."

The code will then upload an invoice file to a vector store and call the assistant to extract the fields instructed using the vector store. After the execution, the thread, vector store and file are deleted.
