CSV export for Zotero with a permutation of each tag/collection/creators. Grab the latest release here.
When bundling tags, you can set the delimiter using the hidden preference SeekTable.delimiter.automatic_tags. If it is 'comma', a comma will be used; if it is CR, LF, or any combinations of those two, those will be replaced with actual carriage returns and linefeeds. If anything else, the text will be used verbatim.
