exporting a specific row from CSV using csvsimple

Question

What is the best way to obtain a specific row (or a subset of row) when I use csvsimple?

⧵csvreader[head to column names]{filename.csv}{}{}

For example, I would like to get only row three from the filename.csv.

Answer 1

You can use

\csvreader[head to column names, filter test = \ifnumequal{\thecsvinputline}{x},]

where x denotes the integer number of a particular row.
