CSV formatter

The CSV formatter presents results of database queries in the following formats:

formatcontent typedescription
csvtext/plaina text table, comma separated, with a header line (dimension names) and \r\n at the end of the lines
csvjsonarrayapplication/jsona JSON array, with each row as another array (the first row has the dimension names)
tsvtext/plainlike csv but TAB is used instead of comma to separate values (MS Excel flavor)
htmltext/htmlan html table
markdowntext/plainmarkdown table

In all formats the date and time is the first column.

The CSV formatter respects the following API &options=:
