Gemini Data Extractor

This tool is a prof-of-concept for extracting data from PDFs and images, using the gemini-2.0-flash-001 LLM from Google. This model attracted a lot of attention lately due to its good performances ad affordable API prices.

It uses Google's GenAI library to interact with the model and extract data from a given document using your prompt. The extracted date is returned in JSON format.

Installation

You can install the tool using pip:

pip install gemini-data-extractor

Usage

You can use the tool by running the following command (see also "Authentication" below):

gemini-data-extractor --path path/to/your/file.pdf --prompt-text "Your prompt here"

The tool will return the extracted data in JSON format to the standard output. In case of a long prompt, you can save it to a file and pass the path to the file using the --prompt-file argument:

gemini-data-extractor --path path/to/your/file.png --prompt-file path/to/your/prompt.txt

Authentication

In order to use the gemini API you need to authenticate either using a gemini studio API key or via the Google Cloud SDK. You can obtain a key from Google AI Studio. You can then authenticate using the --api-key argument or setting the GEMINI_API_KEY environment variable:

gemini-data-extractor --path path/to/your/file.pdf --prompt "Your prompt here" --api-key your-api-key

or

export GEMINI_API_KEY=your-api-key
gemini-data-extractor --path path/to/your/file.pdf --prompt "Your prompt here"

Alternatively, if you have a working Google Cloud Account and the Google Cloud SDK installed, you can authenticate using the gcloud command:

gcloud auth application-default login

Then you can use the tool with the options --project-id and --location (or by setting the GCP_PROJECT_ID and GCP_LOCATION environment variables):

gemini-data-extractor --path path/to/your/file.pdf --prompt "Your prompt here" --project-id your-project-id --location your-location

or

export GCP_PROJECT_ID=your-project-id
export GCP_LOCATION=your-location
gemini-data-extractor --path path/to/your/file.pdf --prompt "Your prompt here"
