Introduction
CSV (Comma Separated Values) files are a widely used data format for exchanging data between different applications and systems. However, the delimiter used to separate values in CSV files may vary, creating challenges when importing or exporting data. Microsoft Excel provides a powerful solution for changing CSV delimiters, enabling seamless data integration.
