Bring your BI to Sigma without a rebuild

Sigma Migration Skills (beta) help your coding agent convert Tableau, Power BI, and Looker dashboards, then check each against the original.

  • Start with an assessment

    Each converter comes with an assessment skill that inventories usage, duplicates, and custom SQL, and shortlists what to move first.

  • Checked against the original

    Parity compares Sigma’s numbers and visuals with the source dashboard on the same warehouse, and it’s green only on a match.

  • Every gap flagged for review

    Anything the skills can’t translate is called out for you to finish in Sigma, instead of guessed.

How it works

One flow for every tool

Ask your coding agent to migrate a dashboard, and the skill takes it from assessment to a verified Sigma workbook, checking in with you along the way.

  1. 1

    Assess

    The assessment skill inventories what you have, from usage to duplicates and custom SQL, and shortlists what to migrate first.

  2. 2

    Discover

    Pull the source definitions, view images, and data, then match each field to columns in the warehouse Sigma reads.

  3. 3

    Model

    Build or reuse a Sigma data model, with calculations translated to Sigma formulas. You approve it before it’s posted.

  4. 4

    Build

    Rebuild the pages and visuals as a Sigma workbook, in the folder and connection you choose, with the layout applied last.

  5. 5

    Verify

    Compare Sigma’s numbers and visuals with the source dashboard. Green means a match; anything else is called out to check.

  6. 6

    Enhance when you’re ready

    Add what the old dashboard couldn’t do, like input tables, apps, or agents, on a copy of the migrated workbook.

Where you’re coming from

Skills for the tools teams move from

Install the converter for your tool. Each one pairs with an assessment skill, and the repo covers more than a dozen BI tools.

What comes across

The skills move the logic, not just the look, so the rebuilt workbooks answer the same questions.

Models first

Your semantic layer becomes a Sigma data model

Measures, calculations, and relationships become a Sigma data model before any workbook is built. When a matching model already exists, the skill reuses it instead of adding another.

  • Tables, relationships, and metrics
  • Calculations translated to Sigma formulas
  • A gap-scout sub-agent learns patterns it hasn’t seen before

Same layout

Pages and visuals rebuilt as Sigma workbooks

Each dashboard comes back as a Sigma workbook on live warehouse data, with its layout applied last so the pages read the way people already know.

Land it first

Data that only lives in the BI tool lands in your warehouse

When data sits inside the old tool instead of a warehouse, bridge skills land it in your warehouse first, so the rebuilt workbooks query it live.

  • Tableau extracts to Snowflake or Databricks
  • Power BI Import-mode models to Snowflake
  • Domo datasets to Snowflake

Parity checked

Green only when it matches the original

Parity compares Sigma’s numbers and visuals with the source dashboard on the same warehouse. Anything the skills can’t translate is flagged for you to finish in Sigma, never guessed.

Install in Claude Code or any coding agent

Add the marketplace, install the converter for your tool, then describe what you want migrated. The skills are agent-neutral, so they also run in Cursor, Cortex Code, and others.

Migration questions

  • What are Sigma Migration Skills?

    Open-source skills that guide a coding agent through moving BI content into Sigma. They assess what you have, rebuild the data model and workbooks, and check the result against the original dashboard. Migrating to Sigma with an AI assistant is in beta.

  • Which tools can I migrate from?

    Converters cover Tableau, Power BI, Looker, Qlik, ThoughtSpot, Amazon QuickSight, IBM Cognos, MicroStrategy, Sisense, GoodData, Domo, Mode, Metabase, and Hex. The repo lists each one’s maturity.

  • Does my data move?

    Sigma queries your warehouse directly, so rebuilt workbooks run on the data where it already lives. When data exists only inside the old BI tool, bridge skills land it in your warehouse first.
