Importing Records into Rayyan

Rayyan supports a wide array of industry-standard file formats and file types, so you can now upload searches from different databases in any accepted "reference format." View this article from Rayyan for step-by-step migration guides to export data from popular sources with examples of supported file formats and types. Guides include Cochrane, EndNote, PubMed, and Web of Science.

Note that Rayyan allows importing 10 files at a time of 100MB per file, allowing 1GB to be imported simultaneously.

Some databases may not export in any of these standard reference formats. In this case, we advise different approaches depending on your context:

  • If you are conducting a systematic review that incorporates search results from more than one database, we advise exporting all of your results into EndNote, Zotero, or another citation manager first. Thoroughly deduplicate your library and then export from your citation manager in RIS format​​​​​​.
  • If you are exporting results from PubMed, Ovid, or EBSCO, first import them from the database to a citation manager such as EndNote or Zotero and then re-export them in RIS format.

For other databases, please contact hslinfo@hawaii.edu if you require assistance.


Adding to an existing Rayyan project

You can add new references/articles to an ongoing review. In the Review Data tab, click Add References. Select the file(s) you want to add, ensuring they are in the correct format.

NOTE: We recommend completing all your database searches, importing all records into a citation management package such as Endnote, and deduplicating your records before importing them into Rayyan.


Editing and deleting records

You can delete an entire import but not individual items.

To delete an entire import, click the trash icon next to the imported reference you are deleting.

Note that this action cannot be undone, and any notes made will be permanently lost.

Managing Duplicates

We strongly recommend removing duplicate records using citation management software such as EndNote or Zotero. Rayyan also offers an option to detect duplicates. After the duplicate detection process is complete, you will be shown the number of duplicates found. When resolving duplicates, you can compare them side by side and choose to keep the left article, the right article, or both. Be sure to carefully review the articles Rayyan compares to ensure accurate and efficient duplicate management.
