one2html

one2html lets you convert OneNote® files (sections or whole notebooks) into HTML.

Installation

Choose one of the following installation options:

1. Download from GitHub Releases.

2. Install via cargo binstall:

cargo binstall one2html

3. Build from source:

cargo install --locked --no-default-features one2html

All options require the latest stable Rust compiler.

If you are using a nightly compiler, you can omit the --no-default-features flag to print stack traces when errors occur during OneNote file parsing.

Usage

Download OneNote files from OneDrive

OneNote files can be retrieved using one of two methods: Either by using onedrive-cli or by downloading a notebook via the OneDrive web UI. To do this first install onedrive-cli following its instructions. After logging in using onedrive-cli login, you can download a section (a single .one file), or a notebook (a folder that contains a .onetoc2 file along with other .one files):

# Download a notebook
onedrive-cli ls Documents/
onedrive-cli cp -R :/Documents/Notebook .

# Download a section
onedrive-cli cp -R :/Documents/Notebook/Section.one .

Alternatively, to download OneNote notebooks via the OneDrive web UI, follow these steps:

1. Visit https://onedrive.live.com
2. Select the folder that contains your notebooks. Typically this is the Documents folder.
3. Use the Download button from the toolbar to download a ZIP file that contains all of your OneNote notebooks.

Convert OneNote files to HTML

OneNote sections are stored in .one files. To convert a section to HTML run:

one2html -i Section.one -o ./output_dir/

OneNote notebooks are stored as folders that contain a .onetoc2 file along with the notebook's sections stored as .one files. To convert a notebook to HTML run:

one2html -i 'Notebook/Open Notebook.onetoc2' -o ./output_dir/

Limitations

• Due to limitations of the OneNote parser only files downloaded from OneDrive are supported. This means you can't convert files created by the OneNote 2016 desktop application using this tool.
