What URL-decode CSV can do:

URL-decode CSV turns any percent-encoded text (like you’d see in URLs or web forms) back into clean, readable CSV. It’s useful when you get CSV data from sources that encode special characters like commas, newlines, or ampersands. The tool works right in your browser no uploads, no server calls. Just paste or load your file, and your decoded data appears instantly.

Example:

Before:

name%2Cemail%0AJohn%20Doe%2Cjohn%40example.com%0AJane%20Smith%2Cjane%40example.net

After:

name,email
John Doe,[email protected]
Jane Smith,[email protected]

Common Use Cases:

If you’ve ever pulled down a URL-encoded string from an API, a query string, or a log file, this is the fastest way to get the original CSV back. It helps decode exported form data, analytics pipelines, or encoded clipboard transfers all without external tools.

Useful Tools & Suggestions:

If you’re unsure what’s encoded, Analyze CSV can help you spot columns full of URL gibberish. And after decoding, run Trim CSV Columns to clean up any lingering padding or artifacts.
