Column Extractor

Extract specific columns from CSV, TSV, or delimited text

Column extraction is a frequent task when working with CSV exports, database dumps, or log files where you only need specific fields. For example, you might have a 20-column CSV but only need columns 1, 3, and 7 for your analysis. This tool lets you specify which columns to extract using their 1-based position numbers and reassemble them with any delimiter you choose — allowing format conversion at the same time.
