Converter Overview

Converter turns selected Tableau workbooks into target-specific migration output. Use it after Analyzer has identified a workbook that is a good candidate for migration, rebuild, validation, or proof-of-concept work.

A conversion job starts with Tableau source content, applies target-specific conversion logic, and produces artifacts, documentation, logs, and next-step guidance for the selected BI platform.

What Converter does

Converter helps teams move from workbook assessment to migration execution.

It can:

• read Tableau workbook structure and metadata
• inspect dashboards, worksheets, fields, calculations, parameters, filters, and data source definitions
• generate source and target documentation
• translate supported logic for the selected target platform
• produce downloadable output when the target workflow supports project artifacts
• record logs and conversion status for review
• provide next-step guidance for validation, redesign, deployment, or rebuild work

Hybrid conversion approach

Converter uses a hybrid approach.

Most of the pipeline is code-driven. Antares uses deterministic code to parse workbook files, inspect workbook metadata, prepare target artifacts, generate documentation, package output, and record processing logs.

LLM assistance is used for tasks that benefit from language reasoning, especially Tableau formula translation into target-platform expressions.

When LLM assistance is used, Antares sends workbook metadata needed for the conversion task. Workbook data values are not sent to the LLM.

How a conversion runs

1. Create a conversion job in Converter.
2. Choose the target BI platform when more than one target is enabled.
3. Upload a Tableau workbook or supported ZIP package.
4. Add screenshots or data files when they are needed for context.
5. Start the conversion.
6. Review status, logs, generated documentation, and target output.
7. Validate, redesign, deploy, or rebuild based on the generated guidance.

Target BI platforms

Antares separates Tableau source analysis from target conversion. The same workbook can be evaluated for different targets, but the generated output and next steps depend on the selected BI platform.

For Power BI migrations

Choose Power BI when the goal is to generate Power BI-oriented output from a Tableau workbook.

Power BI conversions can include:

• a downloadable Power BI project package
• semantic model and report artifacts
• Tableau BRD sections
• Power BI BRD sections
• conversion report
• optional cache artifacts
• Fabric deployment guidance

After conversion, validate the Power BI project, refresh data, review generated model/report files, and deploy to Microsoft Fabric when the output is ready.

For Databricks AI/BI migrations

Choose Databricks AI/BI when the goal is to understand how Tableau content should be rebuilt or validated in a SQL-native AI/BI workflow.

Databricks AI/BI conversions focus on:

• SQL-native migration fit
• dashboard rebuild guidance
• target-specific documentation
• unsupported Tableau interactions
• calculations and data patterns that require target validation
• migration recommendations for AI/BI behavior

After conversion, review AI/BI fit, validate SQL-native dashboard behavior, and plan any required redesign work.

If only one target is enabled for your workspace, Antares uses that target automatically. If more than one target is enabled, choose the target platform when creating the conversion.

Inputs

Converter jobs support:

• one .twb or .twbx workbook
• optional screenshots
• optional data files
• one ZIP package that contains the workbook and optional supporting files

Screenshots help Antares interpret visual layout, mark behavior, labels, tooltips, and dashboard context. Data files are useful when a workbook depends on file-based data sources that are not embedded in the workbook package.

Outputs

Every conversion records status, logs, and generated documentation so reviewers can see what Antares did and where manual validation is still required.

Shared outputs can include:

• Conversion status and processing logs.
• Conversion report.
• Source and target business requirements documentation.
• Downloadable artifacts when the selected target produces project files.
• Context-aware guidance based on detected data source and target platform behavior.

The exact output depends on the selected target platform and the features detected in the Tableau workbook.

Review path

Use the conversion detail page as the review workspace.

Start with the job status and conversion report, then inspect generated documentation and logs. For Power BI output, download and validate the generated project before deployment. For Databricks AI/BI output, use the generated guidance to plan rebuild and validation work.
