How to Convert CSV File Encoding

Open CSV Encoding Converter →What Is the CSV Encoding Converter?
The CSV Encoding Converter attempts to read CSV files that may have non-UTF-8 encoding and re-export them as UTF-8. It detects BOM markers where present and supports common import decoding attempts for formats the browser's TextDecoder API supports. All processing is browser-based.

Open the Tool →Browser-Side Limitations
The browser's TextDecoder API supports a defined set of encodings. For fully reliable multi-encoding conversion, dedicated tools such as iconv or a server-side utility may be more appropriate. This tool is most effective for:
- Files with a BOM marker that need UTF-8 output without BOM.
- Files that are plausibly UTF-8 or Latin-1 (ISO-8859-1) or Windows-1252.
- Detecting encoding signals before deciding on a conversion strategy.

All processing is local. Your files never leave your browser.
