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.

▶️ Quickstart


pip install ydata-profiling


conda install -c conda-forge ydata-profiling

Start 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:

Use case Description
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 ydata-profiling for working with large datasets
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.

Notebook Widgets

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 to_file() function:


Alternatively, the report's data can be obtained as a JSON file:

# As a JSON string
json_data = profile.to_json()

# As a file

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 data.csv dataset.

ydata_profiling --title "Example Profiling Report" --config_file default.yaml data.csv report.html

Additional details on the CLI are available on the documentation.

👀 Examples

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) Open In Colab Binder
  • Titanic (the "Wonderwall" of datasets) Open In Colab Binder
  • 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)

🛠️ Installation

Additional details, including information about widget support, are available on the documentation.

Using pip

PyPi Downloads PyPi Monthly Downloads PyPi Version

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]

Using conda

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:

Filename Requirements
requirements.txt Package requirements
requirements-dev.txt Requirements for development
requirements-test.txt Requirements for testing Requirements for widgets etc.

🔗 Integrations

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:

Integration type Description
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
