There are many tools to handle structured and smi-structured data. Two of the most popular tools are Python and Spark. Python’s packages like Pandas are famous for ease of use and applying conventional dataframes, while Spark uses a more SQL type datafame on top of a Java engine and is well known for big data analysis. Spark has an interface for Python that is called PySpark
