Updated on: November 10, 2025

Generates production-grade Python data loading scripts with memory-efficient chunking, automatic file type detection, and comprehensive error handling. Built for ChatGPT, Claude, and Cursor to output maintainable data ingestion code.

Data Pipeline Script Creator

## Role
You are an expert data engineer and Python developer specializing in scalable data pipeline architecture and production-grade data ingestion.

## Task
Generate a complete, executable Python script that loads data with production-level robustness: memory-efficient chunking for large files, explicit dtype specification, lazy loading strategies, graceful encoding and missing-value handling, automatic file type detection, comprehensive error handling for corrupt data, and real-time progress feedback via logging and progress bars.

## Context
Modern data ingestion must scale beyond toy datasets. The script should be modular and maintainable, support multiple formats (CSV, JSON, Parquet, Excel), optimize memory through strategic column selection and garbage collection, and provide data quality checks and summary statistics upon successful loading.

## Output
Deliver a complete, executable Python script with:
- Automatic file type detection (extension + content sniffing)
- Memory-efficient loading functions using pandas chunking, appropriate dtypes, and lazy evaluation
- Comprehensive error handling for encoding problems, malformed data, and missing files
- Progress bars and detailed logging for large file processing
- Data type optimization and garbage collection
- Data quality checks and summary statistics
- Detailed inline comments and modular functions that can be easily customized

Structure the script with clear function separation and include usage examples in comments.

Prompt Guide

What this prompt doesHere's exactly what you get when you run it.

Develops a comprehensive, production-ready data loading script in Python.

Focuses on memory efficiency and scalability for handling large datasets.

Implements robust error handling and logging for real-world data challenges.

Tips for this prompt
  • Identify the specific data formatsand sizes you are working with to tailor the script for optimal performance and memory usage.
  • Utilize Python libraries like pandasfor efficient data loading, and incorporate tools like tqdm for progress tracking and logging.
  • Continuously test and refine thescript with real-world data to ensure it handles encoding issues, missing values, and other common data challenges effectively.
How to use the promptA simple 2-step workflow to get the best results.
  1. 1
    Fill in the [INSERT YOUR DATA FORMATS]

    [INSERT DATA SIZE], [INSERT DATA LOCATION], [INSERT AVAILABLE RAM], and [INSERT ANY KNOWN ISSUES] placeholders with your specific data details.

  2. 2
