pandas-profiling generates profile reports from a pandas DataFrame. The pandas df.describe() function is handy yet a little basic for exploratory data analysis. pandas-profiling extends pandas DataFrame with df.profile_report(), which automatically generates a standardized univariate and multivariate report for data understanding.

For each column, the following information (whenever relevant for the column type) is presented in an interactive HTML report:

  • Type inference: detect the types of columns in a DataFrame
  • Essentials: type, unique values, indication of missing values
  • Quantile statistics: minimum value, Q1, median, Q3, maximum, range, interquartile range
  • Descriptive statistics: mean, mode, standard deviation, sum, median absolute deviation, coefficient of variation, kurtosis, skewness
  • Most frequent and extreme values
  • Histograms: categorical and numerical
  • Correlations: high correlation warnings, based on different correlation metrics (Spearman, Pearson, Kendall, Cramér’s V, Phik)
  • Missing values: through counts, matrix, heatmap and dendrograms
  • Duplicate rows: list of the most common duplicated rows
  • 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 existance of EXIF metadata

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)

▶️ Quickstart

Start by loading your pandas DataFrame as you normally would, e.g. by using:

import numpy as np
import pandas as pd
from pandas_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="Pandas Profiling Report")

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 pandas_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.

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

Additional details on the CLI are available on the documentation.

📝 Use cases

The documentation includes guides, tips and tricks for tackling commmon use cases:

Use case Description
Profiling large datasets Tips on how to prepare data and configure pandas-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

🔗 Integrations

To maximize its usefulness in real world contexts, pandas-profiling has a set of implicit and explicit integrations with a variety of other actors in the Data Science ecosystem:
