The HEX2BIN function converts a hexadecimal number to a binary number.
1. HEX2BIN Function Syntax
HEX2BIN(number, [Places])
2. HEX2BIN Arguments
number |
Required. The hexadecimal number you want to convert to a decimal number. |
[Places] |
Optional. How many digits to use, if omitted HEX2BIN uses the minimum number of required digits. Tip! Use [Places] for padding with leading 0's (zeros).
HEX2BIN function ignores [Places] argument if the hexadecimal is negative. |
3. Comments
HEX2BIN returns a #NUM! error if an invalid hexadecimal value is used.
HEX2BIN returns the #VALUE! error if [Places] is a non-numeric value.
HEX2BIN returns the #NUM! error value if [Places] is a negative number.
4. HEX2BIN Function Example

Formula in cell C3:
=HEX2BIN(B3)

Convert every hexadecimal to a binary using the table above.
5.1 Example 1
Hexadecimal value 664 is calculated to a binary like this:
Third hexadecimal value: 6 = 0110
Second hexadecimal value: 6 = 0110
First hexadecimal value: 4 = 0100
equals
0110 0110 0100
5.2 Example 2
Hexadecimal value F9F is calculated to decimal like this:
F = 1111
9 = 1001
F = 1111
equals
1111 1001 1111
