What issue do you have?

Hello,

Unfortunately I face an issue with importing OneNote export to Joplin which stops me from start working with Joplin.

Observation

OneNote ZIP-file is extracted to /home/user/.config/joplin-desktop/tmp
2nd folder created there during this process stays empty
Hence also no content is imported to Joplin

from log.txt

2025-10-07 23:24:04: InteropService_Importer_OneNote: Finished

Question

Anybody aware of a workaround or an expected fix date?

Regards,

Thank you for reporting this!

I'm linking to two in-progress or unreleased OneNote importer-related changes that may be related:

A bug fix (originally proposed here) for an issue that prevented certain .zip files from being imported if a warning was emitted prior to processing of the first page.
- This change has been merged and is scheduled to be included in the first 3.5 pre-release (related: Joplin release cycle).
A change to support importing files produced by the OneNote desktop app (proposed, not currently merged). Currently, Joplin only supports importing OneNote files exported from the OneNote web app.

Certain OneNote importer warnings are currently not included in log.txt (they don't use Joplin's logger utility) and only appear in the "Console" tab of the developer tools. It's possible to open the developer tools using the "Toggle development tools" option in the "Help" menu.

This pull request, if merged, should also help debug OneNote import failures.

Thanks @personalizedrefriger

Looks like I’ll be waiting for v3.5.

I downloaded the ZIPs using the export function in onenote.com

Thanks for hint with the console - that’s what’s inside. I am not sure if this relates to the bug fix.

Yes. The "src/lib.rs:26:9:called Option::unwrap() on a None value" matches the issue resolved here.

personalizedrefriger · 10 October 2025 20:32

A v3.5 pre-release is now available. See also: Getting pre-releases.

cgonline · 17 October 2025 12:08

With v3.5.4 I can incompletly import 2 ZIPs and 1 is not working.

Incompletly:
from the console
Error: Error: Malformed OneStore data: not a legacy OneStore file
Not working:
error message
ADM-ZIP: Invalid CEN header (bad signature)

personalizedrefriger · 17 October 2025 16:22

Thank you for testing!

That looks like a failure extracting the OneNote ZIP file. Does extracting, then re-zipping the file's content help?

Context: The import process begins with Joplin extracting the ZIP file using the adm-zip library.

This error happens if the importer fails to parse a .one file's header. It's related to an "is this a supported file" check. There are some changes in the latest dev branch that should improve this error message by providing additional information about the file header.

Details: In particular, this error happens when the guidFile field is not equal to the guidLegacyFileVersion field. I don't see anything in the spec that requires these two fields to have the same value. It may make sense to remove this check and instead rely on the guidFileFormat check, which is currently only present in the latest dev branch.

Related code: Related code: v3.5.4. In the latest dev branch, the related error handling logic is a bit different and may produce a better error message.

Update: I've opened a pull request that may resolve this issue.

cgonline · 17 October 2025 20:00

Opening the ZIP file even doesn’t work. I guess there is a malfunction in MS OneNote online export function - unfortunately this is no FOSS I will try on a different machine to double-check.

personalizedrefriger · 17 October 2025 20:12

Exporting from the OneDrive web UI might help here. To do this:

Open the OneDrive web UI.
Create a new folder.
Copy the notebook to be exported to the folder created in (2).
Download the folder created in (2). It should download as a ZIP file.

cgonline · 18 October 2025 19:34

I tried with v3.5.5 as I saw @personalizedrefriger‘s pull request from yesterday was already included.

During import of a ZIP-file I get the following error now:

InteropService_Importer_OneNote.ts:112
Error: Error: Malformed OneStore data: no revision manifest id found

personalizedrefriger · 18 October 2025 23:45

Thank you for helping test this!

Do you have access to a Windows machine with OneNote desktop installed? If so, exporting from the desktop app (with "file" > "export" > "section" > "OneNote 2010-2016 section (.one)"), then importing the .one file from Joplin might help. The .one files exported from the OneNote desktop app are internally stored differently from those exported from the web app and will be handled differently by the OneNote parser.

I'm not certain, but from a brief look at the relevant source code, that looks like an ID pointing to an item that doesn't exist (or a bug relating to ID resolution). For now, I'm making a note of where the error came from:

Hi, I did a new trial and exported .one-files from Windows 10 OneNote Desktop, put them into a ZIP and started the import in Joplin.

Observations besides that most content is available in Joplin now:

This lead to whole sections are not imported to Joplin.

Furthermore I noticed that the content exported from OneNote Desktop App has deprecated content. Means that sheets which were recently updated do not show latest status. This is of-course no Joplin problem but another reason to leave MS OneNote.

Thank you for testing!

That's good to know. This might still be an importer bug. OneNote export files can contain multiple revisions. One possibility is that Joplin selects the wrong revision during the import process.

I've created a GitHub issue to track this:

bug desktop import

As reported on [the Joplin forum](https://discourse.joplinapp.org/t/onenote-zip-…file-import-not-working/47499/12), the OneNote importer was observed to stop with the following error message: <blockquote> ``` Error: Error: Failed to resolve: Unable to load invalid file reference: <invfdo> (ext: .jpg) (in parser/src/local_onestore/file_node/file_node.rs:771) Location: renderer/src/lib.rs:49:27 (near page Kartoffel - Camembert GratinSamstag, 21.

Currently, Joplin stops the import process (for the current section) with a parser error when this happens. **Expected behavior**: Joplin should gracefully handle the case where an image or other attachment is missing. For example, by substituting the image with a placeholder.
