I’ve just updated the CSV plugin – I don’t consider it finished, but it might already be helpful (and feedback will help us steer it in the right direction).
If you want to try it out, you can download it here. After downloading the zip file you can install it in Tropy’s preferences. You then need to enable the plugin and create a configuration, sort of like this:
You should then be able to export to the plugin via the context menu, using the name you picked for your configuration:
The plugin will export all the fields using the template of the first item you export (and photo paths, tags, notes if you enable it in the configuration). I’m toying with the idea of allowing you to specify fixed template to use instead (that way you could create a template just with the fields you want to export).
