About CSV Column Extractor
The CSV Column Extractor lets you cherry-pick specific columns from a large CSV file and export only those columns. This is useful when you need to share a subset of data, remove sensitive columns, or prepare data for a specific import format.
How to Use
- Upload a CSV file or paste raw CSV text into the input.
- The tool detects column names from the header row automatically.
- Select which columns to keep using the checkboxes.
- Click Extract Columns - the filtered CSV appears in the output.
- Click Download CSV to save the result.
How It Works
The CSV is parsed row by row. For each row, only the values at the selected column indices are included in the output. The output is re-joined with the original delimiter and quoted where necessary.
Example
A sales export with 15 columns - Name, Email, Phone, Address, City, State, Zip, Country, Product, Qty, Price, Discount, Tax, Subtotal, Total. Extract just Name, Email, and Total to create a clean invoice list.
