To prepare your data for creating a pivot table, the data must be "tidy." What does it mean to have tidy data? O Every column has a column header, and the cells within that column contain the data indicated by that header. O The file has been run through an ASCII converter that applies the proprietary TIDY format to the data. O The data is formatted to look attractive to users beyond yourself, as this format will carry through to the pivot table. O The data in all columns must not include commas
