Convert HEX to RGB in Excel

I have a column "HEX" and three columns "R", "G", and "B".

How can I convert a HEX to RGB, e.g. ff0000 to R=255, G=0, and B=0?

I know that the first 2 characters ff belongs to "R", the next 2 00 belongs to "G", and the final 2 00 belongs to "B". So I will have to use =LEFT(A1, 2) for "R", =RIGHT(LEFT(A1, 4), 2), and =RIGHT(A1, 2) for the last.

But how can I convert ff to 255 and 00 to 0, etc.? I guess I will have to do something to parse from hexadecimal (base 16) to decimal (base 10)?

I would like to do it without VBA.

Solution

  • You can convert from hex to decimal using the HEX2DEC() function. For instance:

    =HEX2DEC(A1)

    Where cell A1 contains the string FF, this will return 255.
