When exporting massive datasets from Excel into multiple CSV files, the “best” software depends entirely on whether your data exceeds Excel’s hard limit of 1,048,576 rows. If your dataset fits inside Excel but needs to be parsed out, built-in macro automation is ideal. However, if your data exceeds this limit, you must use external data transformation tools or specialized script libraries to bypass Excel entirely.
