How to convert a csv file with numbers and text that numbers are separated by commas to a new csv file with dots instead

hi everyone

I have a csv file that is contaning numbers and text and numbers are seperated by comma. I want to have new csv file that contain same text and numbers but instead of comma, numbers seperated by dot. I used these codes but it gives me error and it says i can't use strrep. Could you please help me with that. Thank you in advance

M=df2(1:end,2:3)
D=strrep(M, ',', '.')
writematrix(D,"Temp_Dot_Banana5.csv");
