    What is CSV Column Extractor?

    A CSV column extractor lets you select and extract specific columns from a CSV dataset, producing a new CSV containing only the data you need. This is essential for data preparation, privacy compliance (removing sensitive columns before sharing), and simplifying large datasets for focused analysis. Instead of manually deleting columns in a spreadsheet, you specify column numbers (1-based) and the tool instantly produces a clean CSV with only those columns. The extractor handles quoted values, commas within fields, and multi-line values correctly, ensuring data integrity during extraction.
