Upload a Workbook

Workbook upload is the fastest way to get an Antares migration-readiness report for a single Tableau workbook.

Use this path when you want to review one workbook, test a representative dashboard, or understand migration complexity before connecting a full Tableau environment.

When to use workbook upload

Use workbook upload when:

• You have a .twb or .twbx file available.
• You want a fast complexity assessment for one workbook.
• You do not need Tableau environment inventory or usage metrics.
• You want to validate whether a workbook is a good migration or conversion candidate.

If you need inventory, ownership, projects, users, groups, or usage trends across many workbooks, connect Tableau instead.

Supported files

Antares accepts:

• .twb Tableau workbook files.
• .twbx Tableau packaged workbook files.

A .twb file contains the workbook definition. A .twbx file is a packaged workbook and may include workbook assets and file-based dependencies.

The upload flow validates file extension, file signature, archive structure, and archive size to protect the platform from malformed or unsafe uploads.

Upload steps

1. Open the upload page.
2. Drag and drop a .twb or .twbx file, or select the file from disk.
3. Wait for Antares to validate and analyze the workbook.
4. Review the generated migration-readiness report.
5. Export or share results if your tenant enables those actions.

What you get

Uploaded workbook reports can include:

• Complexity tier and migration-readiness signals.
• Detected blockers and warnings.
• Workbook structure summary.
• Calculations, parameters, LOD expressions, and table calculation notes.
• Data source and dependency notes.
• Migration notes for review and planning.

What Antares analyzes

For uploaded workbooks, Antares analyzes workbook structure, including:

• Dashboards, worksheets, and stories.
• Data source references and connection metadata.
• Fields, dimensions, measures, calculations, parameters, and LOD expressions.
• Table calculations and nested calculation complexity.
• Feature usage that affects migration effort.

Limitations

Uploaded workbook analysis does not include Tableau platform usage metrics, ownership context, project inventory, users, or groups.

To include that context, analyze the workbook through a Tableau connection with the required access.

Privacy notes

Antares reads workbook metadata and structure. It does not query or extract business data from the data sources referenced by the workbook.

For packaged workbooks, Antares inspects the package to identify workbook content and file-based dependencies. Upload size limits are configurable by tenant.
