Data Extraction

Data extraction is the process of extracting structured data from unstructured or semi-structured sources such as text documents, web pages, and databases. This involves identifying relevant information and converting it into a format that can be easily utilized by software systems.

Key Concepts

• Structured Data: Refers to information organized in a pre-defined format.
• Unstructured Data: Information that lacks an identifiable structure or organization.
• Semi-Structured Data: Data that has some level of organization but not the strict rules found in structured data, such as XML or JSON files.

Tools and Technologies

• Regular Expressions (Regex): A sequence of characters that define a search pattern.
• Natural Language Processing (NLP): Techniques for analyzing human language to understand context, intent, entities, etc.
• Web Scraping: Automated methods for collecting data from websites.
• Microsoft Excel REGEX Functions: New capabilities including REGEXEXTRACT and REGEXREPLACE for efficient data extraction, cleaning, and formatting within spreadsheets.
