The Excel Oct2Hex function converts an Octal (Base 8) number into a Hexadecimal (Base 16) number

**Syntax**:= OCT2HEX(number, [places])

The OCT2HEX function syntax has the following arguments:

**Number**Required. The octal number you want to convert. Number may not contain more than 10 octal characters (30 bits). The most significant bit of number is the sign bit. The remaining 29 bits are magnitude bits. Negative numbers are represented using two’s-complement notation.-
**Places**Optional. The number of characters to use. If places is omitted, OCT2HEX uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).

**Example**: Let’s look at some Excel OCT2HEX function examples and explore how to use the OCT2HEX function as a worksheet function in Microsoft Excel:

**Syntax**: =OCT2HEX(A2)

**Result**:

Based on the Excel spreadsheet above, the following OCT2HEX examples would return:

**Syntax**: =OCT2HEX(A3)**Result**: BE

**Syntax**: =OCT2HEX(A4)**Result**: ED

**Syntax**: =OCT2HEX(A5)**Result**: 93

**Syntax**: =OCT2HEX(A6)**Result**: 5FF71

**Syntax**: =OCT2HEX(A7)**Result**: 51

**Syntax**: =OCT2HEX(A8)**Result**: FFFFFFFF5B

**Syntax**: =OCT2HEX(A9)**Result**: BE

**Syntax**: =OCT2HEX(A10,B10)**Result**: 05

**Syntax**: =OCT2HEX(A11,B11)**Result**: 0040

**Syntax**: =OCT2HEX(A12,B12)**Result**: FFFFFFFF5B

**Syntax**: =OCT2HEX(A13,B13)**Result**: 040000

**Syntax**: =OCT2HEX(A14,B14)**Result**: 01FFFFF

**Syntax**: =OCT2HEX(A15,B15)**Result**: 0000000008

**Note**:

- If number is negative, OCT2HEX ignores places and returns a 10-character hexadecimal number.
- If number is not a valid octal number, OCT2HEX returns the #NUM! error value.
- If OCT2HEX requires more than places characters, it returns the #NUM! error value.
- If places is not an integer, it is truncated.
- If places is nonnumeric, OCT2HEX returns the #VALUE! error value.
- If places is negative, OCT2HEX returns the #NUM! error value
