What is the CSV Column Extractor?
The CSV Column Extractor is a specialized tool designed to help you clean up wide or cluttered datasets. Often, CSV files export with dozens of columns you don't need—IDs, timestamps, metadata, or duplicates. This tool allows you to isolate exactly the data points that matter to you.
Instead of manually deleting columns in a spreadsheet editor, simply paste your data, check the boxes for the fields you want to keep, and download the refined file.
Key Features
- Column Selection: Automatically detects all headers in your CSV and presents them as a checklist.
- Select/Deselect All: Quickly manage large datasets with bulk selection controls.
- Invert Selection: Easily toggle your choices to pick "everything except" specific columns.
- Instant Preview: See a live preview of your extracted data (first few rows) before downloading.
- One-Click Export: Download your new, lighter CSV file instantly.
- Secure Processing: Your data is processed 100% in your browser and never leaves your device.
