Hi, you can use the transicc utility to do so: 1) Download the windows binaries of lcms2.0a, you need the transicc utility. 2) On your excel, choose "Save as", "Other formats", "text (tab delimited)". Save a temporary text file with your your lab data: in.txt" 3) On a command line session, use the transicc utility in bacth mode, you need -n toggle. Example:
transicc -n -l CIELab_to_UPLab2.icc <in.txt >out.txt 4) In excel, "open" "text files", and then out.txt, choose "delimited" and "Delimiter: space" It worked to me. Otherwise, if you need a perceptually uniform color space, you could give a try to CIE CAM02, which is far better than CIE L*a*b*.
