# Line Ending Header

Use the `Sforce-Line-Ending` header to specify how line endings are formatted.

When you create a Bulk API 2.0 job, specify a line ending that matches the line ending used to create the CSV file using the `lineEnding` request field. Bulk API 2.0 supports two line-ending formats:

- `LF` linefeed
- `CRLF` carriage-return plus linefeed

The default line ending, if not specified, is `LF`. Different operating systems use different characters to mark the end of a line.

Unix / Linux / OS X uses `LF` (line feed, '`\n`', `0x0A`).

Windows / DOS uses `CRLF` (carriage return followed by line feed, '`\r\n`', `0x0D0A`).

For example,

```nolang
{
    "object" : "Account",
    "contentType" : "CSV",
    "operation" : "insert",
    "lineEnding" : "LF"
}
```

Note that it’s possible that the text editor used to create the CSV file is configured for a specific line-ending format and might supersede the default operating system format.
