Examples

Convert a comma-separated file to a pipe-delimited file:

csvformat -D "|" examples/dummy.csv

Convert to carriage return line-endings:

csvformat -M $'\r' examples/dummy.csv

Convert to a tab-delimited file (TSV) with no doubling of double quotes:

printf 'key,value\n1,"a ""quoted"" string"' | csvformat -T -QšŸ

To avoid escaping quote characters when using --quoting 3, add --out-quotechar "":

csvformat -u3 -U3 -QšŸ examples/optional_quote_characters.csv
