A simple Python script that automatically formats text files by:

1. Cleaning extra spaces
2. Capitalizing the first letter of each sentence
3. Ensuring proper spacing around punctuation marks

• Removes multiple spaces and replaces them with single spaces
• Capitalizes the first letter of each sentence
• Fixes spacing around punctuation marks (.,!?)
• Supports input and output file specification

python auto_text_formatter.py input.txt [-o output.txt]

• input.txt: Path to the input text file that needs formatting
• -o output.txt: (Optional) Path to save the formatted text. If not specified, the input file will be overwritten

Input text:

this is a    test.   this is another   sentence!what about this one?    yes,this works too.

Output text:

This is a test. This is another sentence! What about this one? Yes, this works too.

• The script preserves the original text encoding (UTF-8)
• It handles multiple types of sentence-ending punctuation (., !, ?)
• The script will create a backup of your original file if you don't specify an output file
