The following security FAQ outlines what data BIChart accesses, how it is processed, and the controls we employ to protect customer environments and maintain trust.
BIChart is an enterprise software-as-a-service platform designed to help organizations migrate analytics content from Tableau to Microsoft Fabric efficiently and securely. BIChart operates exclusively on customer-authorized metadata to translate dashboards, reports, and semantic structures into Power BI–compatible outputs.
BIChart does not co-mingle, distribute, resell, or reuse customer data or metadata, and it does not access or move underlying record-level data. All access to source environments is explicitly granted and fully controlled by the customer. BIChart’s platform is built to reduce migration friction, accelerate modernization timelines, and maintain enterprise-grade security throughout the process.
This page provides a high-level overview of what BIChart delivers and what is outside the scope of BIChart, to ensure clear expectations for your migration projects.
Visual Migrations
BIChart automatically converts your Tableau visualizations into Power BI equivalents, preserving charts, dashboards, and layouts wherever possible.
Workbook and Report Connection Details
BIChart extracts and transfers ****connection metadata — such as server names, database names, and table references — into the Fabric environment to help reestablish connectivity frameworks.
Metadata Extraction and Transformation
BIChart reads and maps your Tableau workbook metadata (fields, measures, calculated fields, relationships) into corresponding Power BI structures, helping speed up reconfiguration. BIChart translates Tableau calculations into Power BI DAX formulas where feasible.
Support for Tableau to Power BI Migration
BIChart currently supports one-way migration from Tableau to Power BI. Migration from Power BI back to Tableau is not available.
Optimized for Microsoft Fabric
BIChart's migration outputs are aligned specifically with Microsoft Fabric environments to ensure compatibility with the latest Power BI capabilities.
Data Migration
BIChart does not move your underlying data sources (rows of data) from source systems. It focuses solely on migrating your workbook structures and visual models.
Credential or Password Management
BIChart does not retrieve or store your database usernames, passwords, OAuth tokens, or other authentication secrets.
You will need to manually reauthenticate your data sources after migration.
Validation of Migrated Content
BIChart does not perform automated testing, reconciliation, or quality assurance of the migrated dashboards or visual outputs.
Enterprises are responsible for validating the accuracy and completeness of the migrated reports.
Cross-Platform Migrations Beyond Tableau and Power BI
BIChart only supports migrations from Tableau to Power BI. It does not support migrations involving other BI tools (e.g., Looker, Qlik, or Domo), nor does it currently support Power BI-to-Tableau migrations.
