# CSV Column Extractor

Extract specific columns from CSV files. Select which columns to keep and download a new CSV with only the data you need.

**Use this tool:** [CSV Column Extractor](https://findutils.com/convert/csv-column-extractor/)

## Programmatic access

- Browser-only: this tool works on a file, the DOM, or a browser API and has no REST or MCP id.

## Why Use CSV Column Extractor?

When working with large CSV files, you often only need specific columns. Rather than manually deleting unwanted columns in a spreadsheet, use our Column Extractor to quickly select and export only the columns you need. Perfect for data cleaning, report generation, and preparing data for import.

## Tips for Better Results

- Always verify the delimiter before selecting columns. A wrong delimiter will merge multiple fields into a single column.
- Use the preview table to spot formatting issues before downloading. If values look wrong, try switching the delimiter.
- For very wide files with dozens of columns, click Select None first, then check only the columns you need rather than unchecking each unwanted column.
- If you need to combine columns from multiple CSV files, merge them first with the CSV Merger, then extract the columns you want in one pass.
- The downloaded file is UTF-8 encoded. If you open it in Excel and see garbled characters, use Excel's Data > From Text import wizard and choose UTF-8.

## Frequently Asked Questions

### Can I change the column order?

Currently, columns are extracted in their original order. Select columns in any order, but they'll appear in the output following the original file's column sequence.

### Is my data secure?

Yes! All processing happens locally in your browser. Your CSV file is never uploaded to any server.

### Can I extract from multiple files at once?

This tool works with one file at a time. For multiple files, use the CSV Merger tool to combine them first, then extract columns.

### What happens to empty columns?

Empty columns are preserved if you select them. The tool extracts exactly what you choose, including blank cells.

### Can I rename columns?

Not directly in this tool. To rename columns, download the extracted CSV and edit the first row, or use a spreadsheet application.

### What is the maximum file size supported?

There is no hard server limit because everything runs in your browser. In practice, files up to 50 MB work smoothly on most devices. For very large datasets, consider splitting the file first or using a tool like the Spreadsheet Editor for incremental processing.

### Does the tool support TSV or semicolon-delimited files?

Yes. Use the delimiter selector at the top to choose comma, semicolon, or tab. The tool will parse and extract columns according to the delimiter you select, so it works with.csv.tsv, and.txt files.

### Can I extract columns from an Excel file directly?

This tool accepts CSV, TSV, and plain-text formats. If you have an Excel file, first convert it with the Excel to CSV converter, then upload the resulting CSV here to extract the columns you need.

### Will the extracted CSV keep special characters and UTF-8 encoding?

Yes. The extractor preserves UTF-8 encoding, accented characters, and special symbols exactly as they appear in the original file. The downloaded output is encoded in UTF-8 with a BOM for maximum compatibility.

### Is there a way to filter rows while extracting columns?

This tool focuses on column selection only. To filter rows by value, open your file in the CSV Viewer where you can search and sort, then export the filtered result. You can then use the Column Extractor on the filtered output.
