The CSV File Creator can create multiple CSV files at a time. You just select the worksheets you wish to have converted to CSV files, select the output directory, and the CSV files are automatically created!

The CSV File Creator also handles the problem of excess lines being created when one creates a CSV file manually.

You should always check the results of the CSV creation. If you have cells that begin with a leading minus sign or math operator, Excel will almost always truncate the results at 255 characters and may chance the content. This is true even if the cell is formatted as text.
