The VBA HEX function is listed under the data type conversion category of VBA functions. When you use it in a VBA code, **it converts an expression into hexadecimal notation and returns the result as a string**. Hexadecimal notation is just another base for representing numbers in, like binary. You can learn more about it from here.

## Syntax

**Hex(Number)**

## Arguments

**Number**: The numeric value that you want to convert into hexadecimal.

## Example

To practically understand how to use the VBA HEX function, you need to go through the below example where we have written a VBA code by using it:

```
Sub example_HEX()
Range("B1").Value = Hex(Range("A1"))
End Sub
```

In the above code, we have used HEX to convert the number from cell A1 into a hexadecimal notation and return the result as a string in cell B1.

## Notes

- If the value specified is a value other than a number or a string that can’t be recognized as a number, VBA will return the run-time 13 error.
- If the given number is not a whole number, then it is rounded to the nearest whole number.
- If the supplied number is NULL then it will return NULL in the result.
