Question details
The user needs to resolve an issue where the OneNote Notebook Importer gets stuck in an infinite loading loop across multiple devices.

- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Importing a pre-designed notebook into a Microsoft account using the web-based Notebook Importer.
- Observed behavior
- The importer fails to process the notebook and continuously loads indefinitely without completing the import.
Ensure you have a stable internet connection and that your downloaded notebook folder is fully unzipped and not corrupted before attempting the import process.
Use a Supported Modern Web Browser
Switching to a fully supported browser like Microsoft Edge resolves compatibility issues that cause infinite loading.
The web-based Notebook Importer relies on modern web standards. Older browsers, specifically Internet Explorer, lack support for the necessary protocols and will cause the tool to hang or fail.
Exit the browser window where the importer is currently stuck loading.
Open Microsoft Edge, Google Chrome, Mozilla Firefox, or Safari.
Navigate back to the OneNote Notebook Importer page, sign in to your Microsoft account, and select your unzipped notebook folder to upload.

Verify Available OneDrive Storage
The importer will fail to complete if your OneDrive account does not have sufficient space to store the new notebook.
Manually Move the Notebook via OneNote Desktop
If the web importer is completely unresponsive, you can use the desktop application to bypass the web tool and sync your files directly.
Looking for a Lighter Office Suite? Try WPS Office
If you frequently encounter syncing and loading issues with heavy office applications, consider switching to WPS Office. It provides a lightweight, free alternative to Microsoft Office with seamless compatibility for your daily document needs.
- 1. Download WPS Office: Visit the official WPS website to download the lightweight installer.
- 2. Install and Launch: Follow the simple installation prompts and open the WPS Office application.
- 3. Open Existing Documents: Easily open your existing Office files without worrying about format conversion or data loss.

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.
