A pure F# library for parsing the .ipynb notebook file format v4.

It uses System.Text.Json in conjunction with the absolutely amazing FSharp.SystemTextJson library.

There currently is a missing link in the .NET ecosystem between working in .NET notebooks and exporting them to other formats. If you want to use .NET polyglot notebooks for creating documentation or websites, you have to use nbconvert, which is a python tool and therefore requires the setup of a python environment.

This library aims to close that gap by

• providing a type model for the .ipynb format (and the additional magic sauce added by .NET interactive)
• providing an extensible interface for converting polyglot notebooks into other formats

Check the build project to take a look at the build targets. Here are some examples:

# Windows

# Build only
./build.cmd

# build and run tests
./build.cmd runTests

# Linux/mac

# Build only
build.sh

# build and run tests
build.sh runTests

The library is not on nuget currently, so you currently have to clone the repo and build it yourself.

Then you can use it to deserialize a notebook file like this:

open NBFormat.NET
open System.IO

"your/path/to/a/notebook.ipynb"
|> File.ReadAllText
|> Serialization.deserializeNotebook
