Fun Fact
CSV remains one of the most widely used data formats globally, despite being over 50 years old and lacking a formal universal standard.
Historical Context
The CSV format dates back to early mainframe data exchange systems in the 1960s and became widely adopted with spreadsheet software in the 1980s. As data pipelines evolved, CSV column truncation became a common preprocessing step to satisfy strict database field length constraints and improve data reliability.
