Good Data Format

• Has several dimensions and at least one measure.
• Contains raw data that has not been aggregated. (Sizzle will aggregate the data.)
• Ideally has between 100 and 30k rows.

Bad Data Format

• Data has already been aggregated (i.e. summed, averaged)
• Not all column headers have values.
• Numbers contain formatting ($, %).
• Single column contains multiple values (e.g. Date Range)
