PBIXRay

Overview

PBIXRay is a Python library designed to parse and analyze PBIX files, which are used with Microsoft Power BI. This library provides a straightforward way to extract valuable information from PBIX files, including tables, metadata, Power Query code, and more.

This library is the Python implementation of the logic embedded in the DuckDB extension duckdb-pbix-extension.

Installation

Before using PBIXRay, ensure you have the following Python modules installed: apsw, kaitaistruct, and pbixray. You can install them using pip:

pip install pbixray

Getting Started

To start using PBIXRay, import the module and initialize it with the path to your PBIX file:

from pbixray import PBIXRay

model = PBIXRay('path/to/your/file.pbix')

Features and Usage

Tables

To list all tables in the model:

tables = model.tables
print(tables)

Metadata

To get metadata about the Power BI configuration used during model creation:

metadata = model.metadata
print(metadata)

Power Query

To display all M/Power Query code used for data transformation, in a dataframe with TableName and Expression columns:

power_query = model.power_query
print(power_query)

Model Size

To find out the model size in bytes:

size = model.size
print(f"Model size: {size} bytes")

DAX Calculated Tables

To view DAX calculated tables in a dataframe with TableName and Expression columns:

dax_tables = model.dax_tables
print(dax_tables)

DAX Measures

To access DAX measures in a dataframe with TableName, Name, Expression, DisplayFolder, and Description columns:

dax_measures = model.dax_measures
print(dax_measures)

Schema

To get details about the data model schema and column types in a dataframe with TableName, ColumnName, and PandasDataType columns:

schema = model.schema
print(schema)

Relationships

To get the details about the data model relationships in a dataframe with FromTableName, FromColumnName, ToTableName, ToColumnName, IsActive, Cardinality, CrossFilteringBehavior, FromKeyCount, ToKeyCount and RelyOnReferentialIntegrity columns:

relationships = model.relationships
print(relationships)

Get Table Contents

To retrieve the contents of a specified table:

table_name = 'YourTableName'
table_contents = model.get_table(table_name)
print(table_contents)

Statistics

To get statistics about the model, including column cardinality and byte sizes of dictionary, hash index, and data components, in a dataframe with columns TableName, ColumnName, Cardinality, Dictionary, HashIndex, and DataSize:

statistics = model.statistics
print(statistics)
