Keep your original Diigo export. Save the CSV as an independent copy of the data Diigo provided, even after the Mynotes import succeeds.
Import in three steps
-
Export a CSV from Diigo
In Diigo, open Tools → Export and choose CSV. Download the file to your computer.
-
Choose Import Diigo
In Mynotes, open Library & settings → Settings & Data → Data management, then select Import Diigo.
-
Review your library
Open Notes and Tags to check the imported content. You can import the same CSV again without creating duplicate records.
Diigo’s interface may change. Its current help page describes export under Tools → Export and lists several available formats. See Diigo’s official export FAQ.
What transfers—and what does not
Imported into Mynotes
- Webpage notes and their source pages
- Personal notes
- Web highlights and attached annotations
- Tags, page titles, URLs, and available dates
Limited by the CSV format
- Image and file bytes are not included; available image URLs and descriptions remain as reference text
- Exact highlight positions are not available, so imported highlights may not reappear in place on the original webpage
- Original highlight colors are not included; imported highlights use green
- PDF files and PDF-viewer annotations are not imported as Mynotes PDF attachments or annotations
Designed for a safe, repeatable move
- Additive: imported content is merged into the library instead of replacing it.
- Duplicate-aware: importing the same records again does not create extra copies.
- Edit-preserving: an import does not overwrite content you already edited in Mynotes.
- Consistent dates: when Diigo omits a timezone, Mynotes interprets the date as UTC so the result is consistent across Mac, Linux, and Windows.
Keep your imported library under your control.
After reviewing the import, create a complete .mynotes backup from Settings & Data. It includes your live notes, tags, highlights, PDF annotations, and original attachments; local Trash and recovery state are excluded.
