CleansiPy

CleansiPy 🧼📊 Clean your data like a pro — Text, Categorical, Numerical, and DateTime — all in one package.

🚀 Overview CleansiPy is an all-in-one Python package designed to clean and preprocess messy datasets with ease and flexibility. It supports four major data types:

📝 Text – tokenization, stemming, lemmatization, stopword removal, n-gram generation, profanity filtering, emoji & HTML cleaning, and more.

🧮 Numerical – missing value handling, outlier detection, precision adjustment, type correction, and logging.

🧾 Categorical – typo correction, standardization, rare value grouping, encoding (OneHot, Label, Ordinal), and fuzzy matching.

🕒 DateTime – flexible parsing, timezone unification, feature extraction (day, month, weekday, etc.), imputation, and validation.

It’s built for data scientists, ML engineers, and analysts working on real-world data pipelines.

🔧 Installation bash Copy Edit pip install cleansipy 📦 Features ✅ Configurable, modular pipelines ✅ Works with pandas DataFrames ✅ Multi-core processing for speed ✅ NLTK/TextBlob integration for NLP ✅ sklearn support for encoding ✅ Detailed logs and cleaning reports ✅ Auto column detection ✅ Type-safe and test-friendly design

⚡ Quick Start

before doing any thing to avoid errors create a venv:

python -m venv venv

-now activate the venv

venv\Scripts\activate

1. Set up your configuration:

   After installing, run the following command to copy the default config.py to your project directory:

   cleansipy-config
   

   Then edit config.py to set your input/output file paths and other options before running the application.

2. write the main file:

from puripy.app import main
if __name__ == "__main__":
    main()

3. Run the application:

   python main.py
   

🖼️ Logo

The official Puripy logo is included in the package at CleansiPy/assets/logo.png.

To access or display the logo programmatically:

from CleansiPy import get_logo_path, show_logo
print(get_logo_path())
show_logo()

• All main code is inside the CleansiPy/ directory for packaging.
• The logo is in CleansiPy/assets/logo.png and accessible via get_logo_path() and show_logo().
• To run the app: set up config, install requirements, then run python -m CleansiPy.app.

in case you dont get the config.py then use this template :
