BigData / Tableau Interview Questions
What is a Tableau worksheet?
A worksheet is the basic building block of analysis in Tableau — it's the single-view canvas where you actually build one chart or table by dragging fields onto shelves.
- Fields from your data source appear as pills in the left-hand pane, split into Dimensions and Measures.
- Dragging pills onto the Rows, Columns, and Marks shelves determines what's plotted and how.
- Formatting, filters, tooltips, and the choice of mark type (bar, line, map, etc.) are all configured at the worksheet level.
Every worksheet in a workbook can be reused: you build it once, then drop it into as many dashboards or stories as you like, and any change you make to the worksheet automatically reflects everywhere it's used.
Worksheets are intentionally single-purpose — if you need multiple charts side by side, you combine several worksheets on a dashboard rather than cramming multiple views into one worksheet.

If a worksheet is updated, what happens to dashboards that already use it?
