Water damaged mid 2014 Macbook Pro - SSD question
Yes, there is.  OWC makes a USB3 to PCIe Enclosure that will allow you to hook your drive up to a USB port so you can mount the drive and copy over your data.  These are a bit pricey (thanks to Apple's proprietary PCIe interface), but even the cheaper no-name ones are only a few dollars less - go with a trusted brand like OWC.

Another option, is where ever you take your MacBook to get repaired, they should be able to offer this service to you for free or even for a nominal fee.  Rossman Repair Group has the ability to save your data even if it's one of the SSDs that are soldered to the logic board.  (I'm not affiliated; just a very happy customer).
