BigTextFileSplitter by Withdata Software is a focused utility for breaking very large text files into smaller, manageable parts. Ideal for logs, CSVs, TSVs, and other plain-text datasets, it helps you overcome file size limits in editors, spreadsheets, and import tools. You can split files by size or by number of lines, and optionally replicate header rows in each output file so column structure remains intact. The tool is designed for speed and reliability, reading directly from disk to handle files that exceed typical memory constraints. Its clean, straightforward interface makes setup quick, and the output uses consistent naming to simplify organization, automation, and reassembly. BigTextFileSplitter preserves your original file and writes the split segments to a destination you choose, helping data engineers, analysts, and IT teams streamline processing, reduce errors, and move large datasets with confidence.
