Invoice Data Extractor

🧩 Overview

The workflow automates the extraction of structured data from unstructured invoice files stored in Google Drive. It converts the file into plain text, generates a targeted extraction prompt, queries an OpenAI model, and delivers the extracted information in a chat‑friendly format.

⚙️ Main Features

Retrieves an invoice file from Google Drive based on user‑specified parameters.
Parses the file contents into a single text string for downstream processing.
Builds a dynamic prompt that lists the specific fields to extract from the invoice.
Sends the prompt to an OpenAI language model and obtains the extraction results.
Formats the model output as a chat message for easy review.

🔄 Workflow Steps

Component Name	Role in the Workflow	Key Inputs	Key Outputs
Google Drive File Manager	Accesses the invoice file in Google Drive and returns its content.	File ID or selection, operation mode (e.g., Get), credentials	Data (file content)
Parse Data	Converts the raw file data into plain text using a user‑defined template.	Data (file content)	Text (invoice data as a string)
Prompt Component	Creates a detailed extraction prompt that enumerates the desired invoice fields.	Invoice data (text)	Prompt Message (text)
OpenAI Model	Generates the extraction results by evaluating the prompt with the selected model.	Prompt Message	Text (model response containing extracted fields)
Chat Output	Presents the model’s response as a chat‑style message.	Model response (text)	Chat Message (displayed output)

Note: The Label Component is only used to display the workflow description and does not participate in data processing.

🧠 Notes

The Google Drive component requires appropriate OAuth credentials and the specified file must be accessible with the selected operation mode.
Parse Data relies on a template; the default template simply returns the text, but can be customized to filter or reformat the input.
The Prompt Component must include all target fields; the OpenAI model will only extract what is explicitly requested in the prompt.
The workflow uses the gpt‑4o model by default, but the model name can be changed to suit cost or performance requirements.
Model output should be reviewed for accuracy; the workflow assumes the prompt is phrased to return results in a clear, structured format.
Chat Output presents the final text but does not parse or validate the data; downstream systems can ingest the message content if needed.
