Handling Unstructured Data in Python Without LLMs or APIs
Want to learn how to handle unstructured data in Python without relying on LLMs or paid APIs?
In this masterclass on unstructured data, you'll learn how to work with three major types of unstructured data: JSON files, text data, and image data. We'll start by loading and exploring JSON and JSONL files using an online JSON viewer to understand their structure, extracting review data, and converting it into a Pandas DataFrame for analysis.
Then, we'll move into text analysis using Python. You'll learn how to perform sentiment analysis using both a fast classical approach with TextBlob and a modern transformer-based model from Hugging Face. We'll also identify key review aspects like product quality, pricing, comfort, and performance, then analyze sentiment across those categories.
Finally, we'll work with image data using OpenCV and Google's Vision Transformer model. You'll learn how images are structured in Python, how to extract useful features like brightness, blur score, and edge density, and how to classify images using this pre-trained vision model.
This video is perfect for data analysts, data scientists, Python learners, and anyone who wants to build practical data skills for 2026 without depending on external APIs or expensive LLM calls.
