For more information: [Manage import scenarios (SM206025)](https://docs.vismasoftware.no/visma-net-erp/help/integration/integration-windows/manage-import-scenarios-sm206025/index.md), [Manage export scenarios (SM207025)](https://docs.vismasoftware.no/visma-net-erp/help/integration/integration-windows/manage-export-scenarios-sm207025/index.md). To add functions to a formula, you can type them in the Formula text area of the dialog box or select them from the list of formula components available within the dialog box. (Select a function type to view the list of functions of the type, and then select a function.) This topic describes and provides examples of the functions you can use in formulas, broken down by type. ## Conversion functions The available conversion functions, which are used to convert data from one data type to another, are listed below.

Function	Description and example
`CBool(x)`	Converts the expression used as the function argument into a Boolean expression. Returns `False` if the Boolean value is zero; otherwise, returns `True`. Example: `=CBool([CashDiscountAmount]` Here `[CashDiscountAmount]` is used as the function argument.
`CDate(x)`	Converts the expression used as the function argument into a value of the Date type. The argument should be a valid date expression according to the locale selected for the import or export scenario. Example: `=CDate('24/12/2011')` Here a string is used as the function argument.
`CStr(x)`	Converts the expression used as the function argument into a string. If the argument is `Null`, the function returns a run-time error; otherwise, it returns a string. Example: `='(' +CStr([AreaCode])+')'+CStr([Phone])` Here `[AreaCode]` and `[Phone]` are used in the function argument.
`CDbl(x)`	Converts the expression defined in the function argument into a value of the `Double` type. Example: `=CDbl(1.0/[ExchangeRate])` Here `[ExchangeRate]` is used in the function argument.
`CSng(x)`	Converts the expression used as the function argument into a value of the `Single` type. If the expression has a value outside the acceptable range for the `Single` type, this function returns an error. Example: `=CSng([CashDiscountAmount]/[DocAmount])` Here `[CashDiscountAmount]` and `[DocAmount]` are used in the function argument.
CDec(x)	Converts the expression used as the function argument into a value of the `Decimal` type. Example: `=CDec([DocAmount]*0.015)` Here `[DocAmount]` is used in the function argument.
CInt(x)	Converts the expression used as the function argument into a value of the `Integer` type. Example: `=CInt('2012')-Year([DocDate])` Here `[DocDate]` is used in the function argument.
CShort(x)	Converts a numeric value to a value of the `Short` type. Example: `=CShort([CashDiscountAmount])` Here `[CashDiscountAmount]` is used as the function argument.
CLong(x)	Converts a numeric value to a value of the `Long` type. Example: `=CLong([CashDiscountAmount])` Here `[CashDiscountAmount]` is used as the function argument.

If the actual length of the string is less than the specified width, returns the original string.
PadRight(string, width, paddingChar)	Left-aligns the characters in a specified string ( string ), padding with the specified character ( paddingChar ) on the right up to the specified total width ( width ). Example: `=PadRight(CStr([City]), 25, '_')` Here `[City]` is used in the function argument. If the actual length of the string is less than the specified width, returns the original string.
