Fun Fact
CSV remains one of the oldest and most universally compatible data formats, originating before modern databases, yet it still powers global data exchange pipelines today.
Historical Context
CSV emerged in early computing during the 1970s as a simple method for exchanging structured tabular data between incompatible systems. JSON later appeared in the early 2000s as a lightweight machine-readable format for web applications. The need to convert between JSON and CSV reflects the ongoing intersection between modern APIs and traditional data analysis tools.
