## What it is
CleverCSV is a Python package that provides a drop-in replacement for the built-in csv module with improved dialect detection for messy CSV files. It also includes a command-line tool for standardizing messy files and generating Python import code.

## Use cases
- detect the delimiter of a messy csv file
- parse csv files with unknown formatting in python
- standardize inconsistent csv files
- generate python code to import a csv file
- replace python csv module with better dialect detection
- clean up csv files before data analysis

## When to choose
- you need to read CSV files with unknown or inconsistent dialects
- you want a drop-in replacement for Python's csv module
- you need CLI utilities to normalize or inspect CSV files

## When to avoid
- you only handle well-formed, consistent CSV files
- you need CSV handling in a language other than Python

## Facets
- artifact type: library
- maturity: active
- function: parser, csv, cli, data-science
- domain: data-science, files, developer-tools, parsers
- platform: python, cli, cross-platform
- tags: csv-dialect-detection, drop-in-replacement, messy-data, data-wrangling
