Merge Multiple CSV Files Script/Module

[bhargavnova]

Objective

Develop a Python script or module that allows users to merge multiple CSV (Comma Separated Values) files into a single combined CSV file. This tool will provide a convenient way to aggregate data from multiple sources and create a unified dataset.

Features

• CSV File Selection: Allow users to specify a list of CSV files to be merged.

• Column Mapping and Handling: Provide options to handle cases where the CSV files have varying columns, such as skipping or filling missing values.

• Customized Output File Name: Allow users to specify a custom name for the merged CSV file.

• Handle Large Datasets: Ensure that the script can efficiently handle merging large CSV files.

Example Usage

import csv_merger

# Merge multiple CSV files
csv_merger.merge(['file1.csv', 'file2.csv', 'file3.csv'], output_file='merged_data.csv')

# Customize the output file name
csv_merger.merge(['file1.csv', 'file2.csv', 'file3.csv'], output_file='combined_data.csv')

Difficulty: Beginner/ Intermediate

Additional Information

• Consider using libraries like pandas or built-in CSV handling in Python for efficient data processing.
• Ensure that the script provides informative error messages in case of invalid input or other issues during the merging process.
