Why cwtwb and cwprep?

Tableau is powerful, but building and maintaining dashboards and data flows by hand is slow, fragile, and hard to audit. cwtwb and cwprep let AI do the file generation — so your team can focus on the analysis, not the plumbing.

Building takes too long
Building dashboards by hand takes days. Small changes require expert knowledge.
Prep flows are a black box
Prep flows are hard to explain, harder to audit, and break when people leave.
AI tools give insights, not files
Tableau Pulse and Ask Data show you charts. They don't give you files you can actually use.

Why cwtwb & cwprep?

Works with any AI
Compatible with Claude, ChatGPT, Gemini, and DeepSeek. You choose.
Real files, not chat responses
Get .twb and .tfl files you can open, share, and deploy — not just conversation replies.
Built for teams
Version control, compliance checkpoints, and audit trails built in.

Core Capabilities

Dashboard Generator (cwtwb)
Describe your dashboard. Get a .twb file you can open in Tableau.
  • Guided step-by-step: confirms your data, layout, and charts before generating anything — no surprises.
  • Outputs standard .twb and .twbx files (including embedded data) that open directly in Tableau Desktop.
  • Validated against Tableau's official schema so files always open without errors.
Data Flow Generator (cwprep)
Describe your data pipeline. Get a .tfl file you can run in Tableau Prep.
  • Generate complete data cleaning flows from text — no drag-and-drop in the Tableau Prep GUI needed.
  • Outputs .tfl and .tflx files that open and run directly in Tableau Prep, no plugins required.
  • Every step is translated to standard SQL — easy to review, audit, and hand off to your DBA.

Real Results

cwtwb dashboard automation
Dashboard Generation

200 custom dashboards built automatically — each one opened straight in Tableau

A retail group needed 200 custom dashboards fast. Using cwtwb's guided flow, they described what each dashboard should show, confirmed the layout, and generated .twbx files ready to publish. Delivery cost dropped 80%.

cwprep data flow
Data Pipeline

Built an entire data cleaning pipeline from prompts — no GUI required

A finance team replaced their manual Tableau Prep work with cwprep. They described the cleaning steps in text, got .tflx files that opened directly in Tableau Prep, and had a full SQL audit trail for compliance review.
