# TJSONData.AsBoolean

Access the raw JSON value as a boolean

## Declaration

Source position: fpjson.pp line 176

`public property TJSONData.AsBoolean : Boolean read GetAsBoolean write SetAsBoolean;`

## Description

AsBoolean allows access to the raw value as a boolean value. When reading, it attempts to convert the native value of the data to a boolean value. When writing, it attempts to transform the boolean value to a native value. For numbers this means that non-zero numbers result in True, a zero results in False. If either conversion fails, an EConvertError exception is raised.

For TJSONBoolean this will return the native value.

For complex values, reading or writing this property will always result in an EConvertError exception.
