Using FormAttributeToValue and FormDataToValue – 1Ci Support

Scope: managed applications, mobile applications, and ordinary applications.

Best practices

In most cases, FormAttributeToValue is preferable to FormDataToValue.

Sticking to this recommendation will help you to keep the code consistent with other 1C:Enterprise applications. Also, FormAttributeToValue has simpler syntax, that is, less chance to make a code mistake.
FormDataToValue requires the data type to be specified explicitly.Example:

SignaturesTable = FormDataToValue(SignaturesTable, Type("ValueTable"));

In contrast, FormAttributeToValue doesn't require data type to be specified. Example:

SignaturesTable = FormAttributeToValue("SignaturesTable");

1C:Enterprise supports both the FormAttributeToValue and FormDataToValue methods, but the last-mentioned is considered more usable. In terms of efficiency and output, the methods are equal.
