What Extract a CSV Column can do:

This tool isolates one column of data from a full CSV. It’s ideal when you only need to extract emails, names, cities, IDs, or any single field from large tables. You can target the column by name or number, and instantly get a plain text list of values, ready to use in emails, scripts, spreadsheets, or reports. It handles files of any size, runs entirely in the browser, and supports file import and export.

Example:

Input CSV:

Name,Age,City
Alice,30,New York
Bob,27,London
Charlie,33,Sydney

Extracting “City” (or column index 2):

New York
London
Sydney

Common Use Cases:

Use it to pull out one column from a CSV export, like customer emails or product SKUs. Perfect for lists, mail merges, batch jobs, and any situation where you only need one field from a larger dataset.

Useful Tools & Suggestions:

Once you’ve pulled the column out, Convert CSV Columns to an Array is handy if you’re feeding the data into code. And if you’re comparing it with another file, try Compare Two CSV Files to line things up.
