What Change CSV Encoding can do:

Change CSV Encoding lets you instantly switch your CSV file’s character format without needing any external software. Whether you’re prepping a file for a system that only supports Windows-1252 or fixing character display issues caused by mismatched encodings, this tool gives you a simple, browser-based solution. It’s fast, live, and supports safe plain-text formats only. You can preview, convert, and export without ever leaving the page.

Example:

Input:

Name,Location
Alice,Zürich
Bob,東京
Charlie,São Paulo

Output (ISO-8859-1):

Name,Location
Alice,Zürich
Bob,???
Charlie,São Paulo

Common Use Cases:

You’ll find this handy when a file opens with garbled text or when switching between systems that expect different encodings. It’s also useful for checking how your content will behave in environments like Excel, older database tools, or non-Unicode-compatible apps. Just load your file, try a new encoding, and export the clean result.

Useful Tools & Suggestions:

If the characters look scrambled, try Analyze CSV to spot any unusual byte patterns. And once you’ve changed the encoding, run Validate CSV to make sure the structure still parses cleanly.
