What Delete a CSV Column can do:

Delete a CSV Column is a fast way to remove unwanted data columns without opening a spreadsheet. You can target columns either by name (if there’s a header) or by index. It’s handy when dealing with exports that include extra metadata, IDs, or tracking fields you don’t need. The tool updates live as you type and includes controls to manage headers, preview output, and export your final CSV with zero hassle.

Example:

Before:

Name,Age,Email
Alice,30,[email protected]
Bob,27,[email protected]

After deleting column “Email”:

Name,Age
Alice,30
Bob,27

Common Use Cases:

Use it to remove confidential columns before sharing data, trim bloated exports, or clean CSVs before importing into tools that expect fewer fields. Whether you’re a developer, analyst, or just working with spreadsheets, this makes quick edits painless.
