Data conversion is the process of transforming data from one format to another. This is often necessary when different systems or applications need to share information but use incompatible formats. For example, converting a CSV file into a JSON format allows data to be easily used in web applications. The conversion can involve changing the structure, encoding, or type of data. It is crucial in various fields, including database management, software development, and data analysis. Proper data conversion ensures that information remains accurate and usable across different platforms and technologies.
