# converted

A value that indicates whether a filter service converted the file.

## Declaration

```swift
static let converted: NSAttributedString.DocumentAttributeKey
```

## Discussion

Discussion The value of this attribute is an NSNumber object containing an integer. Indicates whether the file was converted by a filter service. If missing or 0, the file was originally in the format specified by documentType. If negative, the file was originally in the format specified by document type, but the conversion to NSAttributedString may have been lossy. If 1 or more, it was converted to this type by a filter service. The string constant in macOS 10.3 and earlier is @"Converted".
