I walk through the new Workbook Optimizer in Tableau 2022.1, a feature that checks your workbook against 12 performance tests and flags where you can improve. I show how it surfaces pass, amber and fail results and recommends specific fixes like removing unused fields.

## Key takeaways

- Tableau 2022.1 introduces the Workbook Optimizer, accessible from the option at the very bottom of the workbook
- It runs 12 performance tests covering things like unused fields, calculations across multiple data sources, calculation types and lengths, and number of data sources
- Results are shown as pass, amber alert, or fail so you can prioritise issues
- It doesn't just flag problems, it recommends specific fixes such as listing the exact unused fields to remove
