BCL files conversion to FASTQ without SampleSheet.csv

Dear community,

I have got NGS data which is basically the BaseCalls folder with .bcl files. I want to know how to successfully convert .bcl files to .fastq format. So far, I have been using the bcl2fastq program, however, I have no SampleSheet.csv file. I have generated my own file like this because the program crashes otherwise.

Is it a good way to do it? Am I missing something? Unfortunately, I have not been working with .btl data so far. Also, I have not done sequencing myself.

By the way, now bcl2fastq doest not crash but spamming this message:
