Description

The Script Meta-Fields Extractor is a Python-based tool designed to extract metadata (field names, data types, and example values) from a variety of file formats, including:

• CSV
• Excel (.xls, .xlsx)
• JSON
• XML
• Parquet
• QVD (with the version 1.1)

The tool processes data files located in the inputs directory and generates metadata reports saved in the outputs directory.

---

Getting Started

Prerequisites

Ensure you have the following installed:

1. Python 3.6+
2. pip (Python package manager)

Installation

1. Clone this repository:

   git clone <repository_url>
   cd script-meta-fields-extractor

2. Install the required Python libraries:

   pip install -r requirements.txt

3. Set up the folder structure:

   • Ensure the inputs folder exists and place your data files inside it.
   • The script will automatically create the outputs folder if it doesn't exist.
