Analyzing randomized data

Hello,
I have distributed an experiment with a pre-measurement, a manipulation and post measurement. I have four conditions in the manipulation, which included only a picture and a text (or video) on each. My participants were randomly assigned to one of the four conditions. Now, when I downloaded the data, I do not find the option to sort the participants by the four conditions. It looks like it is not recorded on the file. Does someone have a clue how to do it?
