I walk through the new Workbook Optimizer introduced in Tableau 2022.1, showing how it runs a series of best-practice tests when you publish and gives guidance on improving workbook performance. I also share my wishlist of features I'd love to see added in future releases.

## Key takeaways

- The Workbook Optimizer appears at the bottom of the publish dialog and runs around 12 best-practice tests without altering your workbook, only offering guidance.
- Failed tests flag issues like unused fields across data sources and calculations using multiple data sources, each with an explanation and a link to support guidance.
- Removing or hiding unused fields cuts unnecessary load and compute time when a workbook is published to production.
- You can rerun the optimizer after making changes and it retains a timestamped score from your last run, acting like a proactive to-do list.
- The feature will also be available in WebEdit in the browser, and Tableau has committed to expanding the tests over time.
