How to open .ipynb file in Spyder?
Question:
without using iSpyder DOS shell commands, how can an .ipynb (Jupyter Notebook) be opened directly into Spyder on Windows? Even the online Jupyter Notebook site prompts for a relative directory path where the file is stored.
- Why isn’t there something that just loads the Notebook how it’s supposed to look without typing a bunch of directory commands,
- and why does Spyder’s RUN button become greyed out when it loads the .ipynb file?
- I have no idea what the .ipynb file format is compared to regular .py files
Opening lines of the .ipynb when loaded in Spyder are:
{
"cells": [
{
"cell_type": "code",
"execution_count": 1,
"metadata": {
"ExecuteTime": {
This does not look like python code whatsoever

Once you install this, you can open native .ipynb files in spyder
From the website:
Spyder plugin to use Jupyter notebooks inside Spyder. Currently it
supports basic functionality such as creating new notebooks, opening
any notebook in your filesystem and saving notebooks at any location.
You can also use Spyder’s file switcher to easily switch between
notebooks and open an IPython console connected to the kernel of a
notebook to inspect its variables in the Variable Explorer.
The jupyter notebook plugin currently works with Spyder 4.2.5 version and will not work with Spyder 5.X versions.
If you are using Spyder-5.x and therefore cannot use the Spyder-notebook plugin (see the other answers), an alternative is to export the .ipynb from Jupyter as an executable .py script first, then open the .py script in Spyder.
Jupyter->Files->Save and Export Notebook as->Executable script
The .py script produced preserves the ipython cells, using the
# In[<cell name or number>]:
syntax, for dividing the code into cells.
In Spyder, you can then right-click on the cell, and select Run cell to execute it in the Spyder console.
Beware, that all the cells (Code, Markdown, and Raw) are saved in the .py script. You may need to add '''block quotes''' around your Markdown and Raw cells, to prevent SyntaxErrors when running the .py script file.
Jupyter Notebook plugin works on Spyder 5.4.0. Tested with plugin 0.4.0 of Sept 2022.
After installing the package using Conda, nothing seems to have changed and opening a Jupyter files just opens a text file, without interpreting any markdown inside, like it does without the plugin.
However there is now a tab row at the bottom of the editor:
You must switch to Notebook in order to work with Jupyter files. Use the double burger icon at top-right corner to open a file. Then you can execute the loaded file.
I noted some errors and differences in graphic outputs, but as the interface is really different from Spyder interface, I just copied the code into a regular Python file to get rid of Jupyter format dependency and I didn’t dig further.
There is a warning on the site: Spyder’s standalone installer does not allow you to add plugins. I don’t know what it means, nor what does mean this other indication:
At the moment it is not possible to use this plugin with the Spyder installers for Windows and macOS. We’re working to make that a reality in the future.
As I mentioned, the plugin was installed using Conda, in the environment used by Spyder, which is selected in the preferences, under Python Interpreter.
