Use Smart Cleanup features like Cleanup Suggestions and Column Stats to organize, standardize, and clean raw data before you analyze.

• At the top, click Data  Data cleanup  Cleanup suggestions. 
• If you import data into a sheet and suggestions are detected, a Data cleanup notification will appear on the bottom right > click See all.

2. Cleanup suggestions will show in the sidebar.

Use Column Stats

Use Column Stats to view insights about the values within a column, so you can identify problems or quickly get a sense of what your data looks like. You can view visualizations (count and distribution), frequency tables (to quickly view the most and least frequently occurring values), and summary statistics at the column level.
