Hexadecimal (base 16), decimal (base 10), octal (base 8), and binary (base 2) are the most commonly used numeral systems in engineering and computing. Therefore, Excel has provided functions to convert numeric values to and from each of these systems. The Excel Hex2Oct function converts a Hexadecimal (Base 16) number into an Octal (Base 8) number.
Syntax: HEX2OCT( number, [places] )
Where the function arguments are :
|number||–||The hexadecimal number that is to be converted to octal.|
|[places]||–||An optional argument, which specifies the number of characters that you want the returned octal number to have.
If this is greater than the minimum, the octal number will be padded out using leading zeros.
If omitted, the returned octal uses the minimum number of places.
Note that the number argument must be no more than 10 characters (40 bits) long. The most significant bit of this value denotes the sign of the number and the remaining 39 bits denote the magnitude. Negative numbers are represented using two’s complement notation. It should also be noted that, as hexadecimals use the numbers 0-9 and the characters a-f, they should be enclosed in quotation marks when they are supplied to an Excel function. (eg. The hexadecimal 11a should be input as “11a”).

Hex2Oct Function Common Errors
If you get an error from your Excel Hex2Oct function this is likely to be one of the following :
