I believe there missed the most simple way to resolve the topic.

You can just use `tr “,” “\t“`.

For example:

$ echo 'one,two,three' | tr "," "\t"

Does it make sense for you?

@Jose,

To separate the data fields of a CSV file into a TSV (Tab-Separated Values) format using the following awk command.

$ awk 'BEGIN { FS=","; OFS="\t" } { print $1, $2, $3, $4 }' tecmint.csv > tecmint.tsv

This command assumes that your input file is named tecmint.csv, and the resulting TSV file will be named tecmint.tsv.

“While CSV files separate values with commas, TSV files use tabs, which can make data handling easier, especially when dealing with commas within the data itself.”

These methods will convert all commas to tabs, not just the ones that separate the data fields.
