Combine multiple csv files with the cat command?

[amelinevallet]

Dear Andrew, I'd like to use xsv and the cat command to combine column-wise several csv files located in the same directory (from where the cmd prompt is launched). I tried the following command: xsv cat columns .csv -o myfile.csv (naively inspired from copy .csv > myfile.csv). But it did not work. Is there a way to do multiple (i.e. more than 2) file combinaison with xsv? What is the correct command then? Does it requires to have a list of filenames beforehands, or is there a way to combine all files meeting one condition (.csv extension in my example). Many thanks in advance for your help, Améline

When asking questions like this, please provide the exact command you used, the input files, actual output and expected/desired output. Saying "it doesn't work" doesn't help much unfortunately.

I've used this command with some success before, it assumes columns are in the same order though
