Core Capabilities

Guided Authoring

Guided Step-by-Step

Walk through data → layout → charts → style. Each step is confirmed before moving on. No AI guesses, no surprises.

Safe Migration

Edit Existing Workbooks

Open, modify, and re-save .twbx files including their embedded data. Migrate dashboards to a new data source without rebuilding from scratch.

Chart Recipes

Complex Charts, One Instruction

Built-in recipes for dual-axis, butterfly, Sankey, and more. One instruction builds the full chart - layout, color, and labels included.

Validation

Files That Always Open

Every file is checked against Tableau's official schema before delivery. No corrupted files, no mysterious error messages when opening.

FAQ

Do I need to know Tableau to use cwtwb?

No. You describe what you want in plain language and cwtwb handles the Tableau-specific file structure. Knowing basic Tableau concepts like dimensions, measures, and mark types still helps you write better prompts.

How is this different from asking ChatGPT to write a TWB file directly?

Generic LLM output often produces XML that looks plausible but fails in Tableau because the file format has many undocumented constraints. cwtwb uses a purpose-built engine and validates files before delivery.

Which AI models are supported?

Any model that supports MCP tool calls can work, including Claude, ChatGPT through an MCP bridge, Gemini, and DeepSeek. cwtwb is model-agnostic by design.

Will the layouts display correctly in Tableau Desktop?

Yes. cwtwb computes layout structure and positioning explicitly, so dashboards open in Tableau Desktop as intended instead of relying on approximate XML generation.

Can I use my company brand colors?

Yes. You can define brand colors and styling once in your recipe or prompt conventions, and cwtwb applies them consistently across generated dashboards.

What happens if my data source changes?

cwtwb can remap field references from old names to new ones and update the workbook automatically, so you do not need to rebuild the dashboard from scratch.
