data wrangling
Preparing messy information
Data wrangling is the process of cleaning, restructuring, and preparing raw data for analysis.
It involves fixing inconsistencies, handling missing values, and transforming data into usable formats: I spent three hours on data wrangling before I could even start the actual analysis.
Also called data munging.
