ydata-profiling primary goal is to provide a one-line Exploratory Data Analysis (EDA) experience in a consistent and fast solution. Like pandas
df.describe() function, that is so handy, ydata-profiling delivers an extended analysis of a DataFrame while allowing the data analysis to be exported in different formats such as html and json.
The package outputs a simple and digested analysis of a dataset, including time-series and text.
Looking for a scalable solution that can fully integrate with your database systems?
Leverage YData Fabric Data Catalog to connect to different databases and storages (Oracle, snowflake, PostGreSQL, GCS, S3, etc.) and leverage an interactive and guided profiling experience in Fabric. Check out the Community Version.
pip install ydata-profiling
conda install -c conda-forge ydata-profiling
Start by loading your pandas
DataFrame as you normally would, e.g. by using:
import numpy as np import pandas as pd from ydata_profiling import ProfileReport df = pd.DataFrame(np.random.rand(100, 5), columns=["a", "b", "c", "d", "e"])
To generate the standard profiling report, merely run:
profile = ProfileReport(df, title="Profiling Report")
📊 Key features
- Type inference: automatic detection of columns' data types (Categorical, Numerical, Date, etc.)
- Warnings: A summary of the problems/challenges in the data that you might need to work on (missing data, inaccuracies, skewness, etc.)
- Univariate analysis: including descriptive statistics (mean, median, mode, etc) and informative visualizations such as distribution histograms
- Multivariate analysis: including correlations, a detailed analysis of missing data, duplicate rows, and visual support for variables pairwise interaction
- Time-Series: including different statistical information relative to time dependent data such as auto-correlation and seasonality, along ACF and PACF plots.
- Text analysis: most common categories (uppercase, lowercase, separator), scripts (Latin, Cyrillic) and blocks (ASCII, Cyrilic)
- File and Image analysis: file sizes, creation dates, dimensions, indication of truncated images and existence of EXIF metadata
- Compare datasets: one-line solution to enable a fast and complete report on the comparison of datasets
- Flexible output formats: all analysis can be exported to an HTML report that can be easily shared with different parties, as JSON for an easy integration in automated systems and as a widget in a Jupyter Notebook.
The report contains three additional sections:
- Overview: mostly global details about the dataset (number of records, number of variables, overall missigness and duplicates, memory footprint)
- Alerts: a comprehensive and automatic list of potential data quality issues (high correlation, skewness, uniformity, zeros, missing values, constant values, between others)
- Reproduction: technical details about the analysis (time, version and configuration)

📝 Use cases
YData-profiling can be used to deliver a variety of different use-case. The documentation includes guides, tips and tricks for tackling them:
|Comparing datasets||Comparing multiple version of the same dataset|
|Profiling a Time-Series dataset||Generating a report for a time-series dataset with a single line of code|
|Profiling large datasets||Tips on how to prepare data and configure
|Handling sensitive data||Generating reports which are mindful about sensitive data in the input dataset|
|Dataset metadata and data dictionaries||Complementing the report with dataset details and column-specific data dictionaries|
|Customizing the report's appearance||Changing the appearance of the report's page and of the contained visualizations|
|Profiling Databases||For a seamless profiling experience in your organization's databases, check Fabric Data Catalog, which allows to consume data from different types of storages such as RDBMs (Azure SQL, PostGreSQL, Oracle, etc.) and object storages (Google Cloud Storage, AWS S3, Snowflake, etc.), among others.|
Using inside Jupyter Notebooks
There are two interfaces to consume the report inside a Jupyter notebook: through widgets and through an embedded HTML report.
The above is achieved by simply displaying the report as a set of widgets. In a Jupyter Notebook, run:
The HTML report can be directly embedded in a cell in a similar fashion:
Exporting the report to a file
To generate a HTML report file, save the
ProfileReport to an object and use the
Alternatively, the report's data can be obtained as a JSON file:
# As a JSON string json_data = profile.to_json() # As a file profile.to_file("your_report.json")
Using in the command line
For standard formatted CSV files (which can be read directly by pandas without additional settings), the
ydata_profiling executable can be used in the command line. The example below generates a report named Example Profiling Report, using a configuration file called
default.yaml, in the file
report.html by processing a
ydata_profiling --title "Example Profiling Report" --config_file default.yaml data.csv report.html
Additional details on the CLI are available on the documentation.
The following example reports showcase the potentialities of the package across a wide range of dataset and data types:
- Census Income (US Adult Census data relating income with other demographic properties)
- NASA Meteorites (comprehensive set of meteorite landing - object properties and locations)
- Titanic (the "Wonderwall" of datasets)
- NZA (open data from the Dutch Healthcare Authority)
- Stata Auto (1978 Automobile data)
- Colors (a simple colors dataset)
- Vektis (Vektis Dutch Healthcare data)
- UCI Bank Dataset (marketing dataset from a bank)
- Russian Vocabulary (100 most common Russian words, showcasing unicode text analysis)
- Website Inaccessibility (website accessibility analysis, showcasing support for URL data)
- Orange prices and
- Coal prices (simple pricing evolution datasets, showcasing the theming options)
- USA Air Quality (Time-series air quality dataset EDA example)
- HCC (Open dataset from healthcare, showcasing compare between two sets of data, before and after preprocessing)
Additional details, including information about widget support, are available on the documentation.
You can install using the
pip package manager by running:
pip install -U ydata-profiling
The package declares "extras", sets of additional dependencies.
[notebook]: support for rendering the report in Jupyter notebook widgets.
[unicode]: support for more detailed Unicode analysis, at the expense of additional disk space.
[pyspark]: support for pyspark for big dataset analysis
Install these with e.g.
pip install -U ydata-profiling[notebook,unicode,pyspark]
You can install using the
conda package manager by running:
conda install -c conda-forge ydata-profiling
From source (development)
Download the source code by cloning the repository or click on Download ZIP to download the latest stable version.
Install it by navigating to the proper directory and running:
pip install -e .
The profiling report is written in HTML and CSS, which means a modern browser is required.
You need Python 3 to run the package. Other dependencies can be found in the requirements files:
|requirements-dev.txt||Requirements for development|
|requirements-test.txt||Requirements for testing|
|setup.py||Requirements for widgets etc.|
To maximize its usefulness in real world contexts,
ydata-profiling has a set of implicit and explicit integrations with a variety of other actors in the Data Science ecosystem:
|Other DataFrame libraries||How to compute the profiling of data stored in libraries other than pandas|
|Great Expectations||Generating Great Expectations expectations suites directly from a profiling report|
|Interactive applications||Embedding profiling reports in Streamlit, Dash or Panel applications|
|Pipelines||Integration with DAG workflow execution tools like Airflow or Kedro|
