This is a stellar plugin with great support.

I’ve got a couple websites I’ve built specifically to be searchable libraries of data, so they have enormous numbers of records and dozens of custom fields for all the metadata. This plugin saves my bacon every time we make major changes – I’ve been able to sync sites from staging to production with ease by using the All Export plugin alongside, and it’s even been helpful during the build process when importing the content from spreadsheets. I’ve never been so satisfied with a commercial plugin, and their support responses are really fast.
