Text data refers to any information that is represented in a written format. This can include anything from books, articles, and emails to social media posts and chat messages. Text data is often unstructured, meaning it does not have a predefined format, making it more challenging to analyze compared to structured data like spreadsheets. Text data is commonly used in various fields, including natural language processing and data analysis. By analyzing text data, researchers and businesses can gain insights into trends, sentiments, and user behavior, helping them make informed decisions based on the information gathered from written content.
