CSV Column Extractor
Extract specific columns from CSV data
Frequently Asked Questions
How do I specify which columns to extract?
Enter column numbers separated by commas in the "Column Numbers" field. Use 1-indexed positions (first column is 1, not 0). For example, "1,3,5" extracts the first, third, and fifth columns.
What delimiters are supported?
The tool supports common delimiters: comma (,), semicolon (;), tab, and pipe (|). Select the appropriate delimiter that matches your CSV format.
What happens if a column doesn't exist in a row?
If a specified column doesn't exist in a particular row, it will be left empty in the output. The tool won't throw an error, but the field will be blank.
Can I extract columns from complex CSV files?
The tool handles basic CSV files well but might not properly parse CSV with complex features like quoted fields containing commas. For complex CSV files, consider using a full-featured CSV parser.
