Launch a modern browser

Open Microsoft Edge, Google Chrome, Mozilla Firefox, or Safari.

Retry the import process

Navigate back to the OneNote Notebook Importer page, sign in to your Microsoft account, and select your unzipped notebook folder to upload.

Frequently Asked Questions

Why doesn't the OneNote importer work on Internet Explorer?

Internet Explorer is an outdated browser that does not support the modern web standards required by the OneNote Notebook Importer. It is recommended to use Microsoft Edge or other current web browsers.

What format should the notebook be in before importing?

Exported OneNote notebooks are usually downloaded as ZIP files. Before using the web importer, you must extract the ZIP file. The importer expects you to select the entire unzipped folder containing the .one and .onetoc2 files.

How do I know if the notebook import was successful?

Once successfully imported, a checkmark will appear on the importer screen. You can then click the provided link to view your notebook, and it will appear in your notebook list on the OneNote app or OneNote for the Web.

Can I import a OneNote notebook from a Mac?

The OneNote Importer tool was primarily designed for Windows folder structures. Mac users generally need to rely on OneDrive syncing or use a Windows device/virtual machine to upload local notebooks to their Microsoft account.
