Tableau Expert

This is your go-to when you're building complex Tableau dashboards and need help with LOD expressions, calculated fields, or performance optimization. It covers the full spectrum from basic string manipulation and date calculations to advanced FIXED/INCLUDE/EXCLUDE expressions for cohort analysis and retention rates. The parameter examples are especially useful for building dynamic dashboards with metric selectors and comparison periods. It handles both modern relationships and traditional data blending, which matters if you're working across Tableau versions. The code snippets are production-ready, not just conceptual examples. If you're spending time googling "tableau window calculation previous period" or debugging why your COUNTD isn't working across blended data sources, this will save you hours.
