Convert TSV to GitHub tables in AWK

#!/usr/bin/env awk -f

BEGIN {
  FS = "\t"
  OFS = "|"
}

{
  printf OFS

  for (i = 1; i <= NF; i += 1)
    printf $i OFS

  printf "\n"
}

NR == 1 {
  printf OFS

  for (i = 1; i <= NF; i += 1)
    printf "---" OFS

  printf "\n"
}

A tiny AWK program to make GitHub tables from TSV. (Useful for database results, like Snowflake.) Here are some more details about tables in Markdown.

There might be a better way to do this in AWK. Feel free to educate me. I’m pretty new at it.
