CSV
Comma-Separated Values
CSV is the lowest common denominator of tabular data — one row per line, fields separated by commas, quoting rules that every implementation interprets slightly differently. Excel, Google Sheets, every database export tool and every analytics platform reads and writes it, which is exactly why so much data has to pass through it.

Opening a .csv file
If you landed here because something handed you a .csv file and
nothing on your machine will open it, converting it to a format you already have a
reader for is usually faster than installing new software. Every conversion above runs
in this browser — the file is not uploaded, so it works on a locked-down work machine
and on a file you are not allowed to send anywhere.
