This article explores how to address type conversion issues caused by integer overflow when importing CSV files using Pandas' read_csv function. When numeric-like columns (e.g., IDs) in a CSV contain numbers exceeding the 64-bit integer range, Pandas automatically converts them to int64, leading to overflow and negative values. The paper analyzes the root cause and provides multiple solutions, including using the dtype parameter to specify columns as object type, employing converters, and batch processing for multiple columns. Through code examples and in-depth technical analysis, it helps readers understand Pandas' type inference mechanism and master techniques to avoid similar problems in real-world projects.
