What Swap CSV Columns can do:

Swap CSV Columns gives you fast control over rearranging column order in any CSV file. Whether you’re fixing data exports, matching API expectations, or cleaning up spreadsheets, this tool makes it simple to pick two columns and swap their positions without affecting the rest of the data. It works instantly in your browser, with no need for Excel or scripting.

Example:

Input:

Name,Age,Location
Alice,30,USA
Bob,25,UK
Charlie,35,Canada

After Swapping “Name” and “Location”:

Location,Age,Name
USA,30,Alice
UK,25,Bob
Canada,35,Charlie

Common Use Cases:

Use this when exporting data to another system that expects a different column order, or when quickly correcting column placement in a messy dataset. It’s perfect for quick edits and checks without opening a spreadsheet program or writing code.

Useful Tools & Suggestions:

Before swapping, run Count CSV Columns so you know exactly which ones you’re working with. And after the swap, Validate CSV is a quick check to make sure the structure’s still solid.
