• Decide how the columns and the data in the sheet will be mapped with smart mapping suggestions
• Know where are the errors in your data and fix them on the spot before importing the data
• Get formatting errors automatically fixed on the sheet with one click
• Find & replace data on the sheet directly on the console
• Download the fixed version of the sheet so you can keep a copy of the fixes you made
