Aug 30, 2024 at 17:54 comment added user256787 Thank you. awk 'BEGIN{FS=OFS=","} {sub(/ +$/,"")} NR==1{gsub(/ /,FS)} NR>1{$1="\""$1"\""} {print $2, $3, $1}' pc0.csv > pc1.csv worked perfectly.
Aug 30, 2024 at 5:12 comment added kos Huh, looking at this made me notice something; the trailing spaces you're removing, which I thought were just a refuse in OP's example, may actually be the "tabs" I now notice they're mentioning at the end of the question. +1 as this is the correct solution given the proposed input, however OP should clarify this.
