Introducing trimtrain: An Efficient Tool for Space Normalization

trimtrain allows you to clean and normalize a dataset so that all data is separated by single spaces for further text processing.

Key Features

  • Simplicity: trimtrain is designed with simplicity in mind. It does one thing and does it well - normalizing data columns.
  • Flexibility: Whether you're working with text files that have spaces or tabs as separators, trimtrain seamlessly handles both, making your data uniformly spaced. The output separator is configurable for different workflows.
  • Efficiency: Optimized for performance, trimtrain can process large files quickly, making it a highly useful tool in your data processing toolkit.
