I managed to solve my problem.

I missed it both from the logs and the docs, but actually this codec plugin (csv) doesn't come installed, so you have to install it first with:

`bin/logstash-plugin install logstash-codec-csv`

After that I had to escape newline from fields to avoid unwanted line breaks:

```auto
mutate {
    gsub => ["[Query]", "[\n]", "\\\\n" ]
    gsub => ["[PreparedQuery]", "[\n]", "\\\\n" ]
}

```

The plugin will take care of doubling any double quote in the data (that's how you escape doublequotes).

For the separator I have opened another thread in the forum, see:

If this is not possible, how would I have to modify the code to make it possible?
