Simple CSV Exporter

Simplicity is the key to a powerful tool.  This is the sister plugin of Really Simple CSV Importer, and both do a remarkable job of manipulating post data in and out of the DB. 

The one thing missing is the ability  to export other types of data, users, taxonomies, attachment meta-data...it would be a real complete swiss-army knife with the ability to also export these other data types.  This way you can batch fix missing pieces of meta-data in your DB by simply sorting through it in a google sheet
