Importing a Mendeley Library Into Zotero (Alternative Local Method)
Zotero can import from an online Mendeley library, and we recommend using that method if possible.
If for some reason you're unable to perform an online import, it's possible to import from a local Mendeley Desktop database, but you'll first need to install an old version of Mendeley Desktop. Later versions of Mendeley Desktop began encrypting the local database, preventing you from getting your own data out of the app.
To perform a local import, follow these steps:
- Make sure you've synced all data and files in your current version of Mendeley. Syncing data alone isn't enough, since Mendeley sync doesn't make any information about attached files available unless you actually sync the files themselves.
- If already using Mendeley Desktop, make a backup of your Mendeley database.
- Close Mendeley Desktop
- Download and install Mendeley Desktop 1.18 using the links below.
- Open Mendeley Desktop 1.18 and perform a fresh sync to pull down your Mendeley data from the Elsevier servers. (If Mendeley doesn't open, you may need to go to your Mendeley data directory and move the file ending with
@www.mendeley.com.sqliteout of the way.)
- Verify that all your data and files are available locally. If some files are unavailable, it may help to add all items in the library to a folder and restart Mendeley Desktop.
- Make sure you're running Zotero 6, which contains the latest version of the importer as well as a new PDF reader that can display PDF annotations imported from Mendeley.
- Start the import in Zotero by going to File → “Import…”, choosing the file option, navigating to your Mendeley Desktop data directory, and selecting the file with the filename
By default, the Mendeley data directory can be found at the following locations:
%LOCALAPPDATA%\Mendeley Ltd.\Mendeley Desktop\
/Users/<username>/Library/Application Support/Mendeley Desktop/
~/.local/share/data/Mendeley Ltd./Mendeley Desktop/
