What actually changes
TSV and CSV are not the same picture in two wrappers.
The delimiter changes from tab to comma, and every field that now contains a comma is quoted so the structure survives.
Worth knowing first
This is exactly where naive conversions corrupt data. A field containing a comma, which was perfectly safe in TSV, must be quoted in CSV or the row silently gains a column. Free-text and address fields are where it happens.
Questions
TSV to CSV, answered
Why is TSV used at all?
Tabs almost never appear inside data fields, so TSV needs far less quoting and escaping than CSV. Scientific tooling prefers it for that reason.
What happens to embedded newlines?
They are quoted, and the CSV reader on the other end must support multi-line fields. Many simple parsers do not.
