Binary to hex

[daverunt]

Hi,

I am trying to find a better way to convert a binary string to a hex string.

At the moment I have a binary digit per cell A1 to H1
I concatenate them to a string

Cell I1 contains
=CONCATENATE(A1,B1,C1,D1,E1,F1,G1,H1)

I convert to hex for cell J1 using

=BIN2HEX(LEFT(I1,4))&BIN2HEX(RIGHT(I1,4))

Can the 2 formulas be combined?

Assuming that the value in A1 through H1 is either a 1 or a 0, the following formula will combine them and convert the result to HEX.

Perhaps try

=BIN2HEX(A1&B1&C1&D1&E1&F1&G1&H1,2)

Thanks guys

both work but Mike yours only returns 1 character if there are 4 zeros, whereas Barrys is set to return 2 characters.

Thanks for the help.

I didn't notice the second parameter for the BIN2HEX function. This will also return two characters with a leading zero if needed:

=BIN2HEX(SUMPRODUCT(A1:H1,10^{7,6,5,4,3,2,1,0}),2)

Thanks Mike,
