Tableau is powerful. Getting help with it shouldn’t be this hard.
AI gives you wrong answers about Tableau
“ChatGPT is absolutely convinced that SPLIT uses [0] for the index, despite square brackets not being used anywhere in Tableau.”
You paste your LOD expression into an AI and get back something that looks right but is completely wrong — because the AI doesn't know your data model, your fields, or your relationships.
Inheriting a workbook is a nightmare
“100 calculated fields. No documentation. Fields named calculation_13074849303389.”
You inherited this workbook from someone who left. Everyone depends on it. You're afraid to touch anything.
10 years of experience and LODs still don't make sense
“I have 10+ years Tableau experience and 20 years SQL experience and I still get turned around with LODs.”
The documentation is scattered. The workarounds conflict with each other. And the more complex your workbook gets, the more impossible it is to debug.
The problem isn’t you. It’s that no AI has ever been able to see inside your workbook — until now.
What if AI actually knew your workbook?
Ask about any calculation and get a real answer
Drop your workbook, ask "What does this LOD do?", and get an explanation that references YOUR fields, YOUR relationships, YOUR actual data structure — not generic examples from the docs.
Inherit any workbook with confidence
Every field, calculation, parameter, and dashboard relationship — decoded and organized in seconds. No more clicking through worksheets or parsing XML by hand.
Go from stuck to unstuck in one drop
Performance issues, cryptic errors, filter behavior that makes no sense — get answers that account for YOUR specific workbook context, not Stack Overflow posts from 2014.
The missing piece was always context. Generic AI doesn’t work for Tableau because it can’t see your workbook. VizWhiz changes that.
