Question: what do you use as a tabular data viewer in debug mode?

[manos-msdn]

For example if there is a dataframe in a debugger variable and I want to visualise it as a table, what can I use? When I choose "View value in data viewer", it comes up with a popup window:

but when I click yes and we search the extensions with "@tag:jupyterVariableViewers" nothing comes up

Also not sure why it searches for jupyterVariableViewers as I am not running inside a jupyter file, but even if I remove that word and search just for VariableViewers, again nothing

Thanks

1. Manually install Jupyter & Python extensions

Even if you're not in a Jupyter file, the viewer relies on those extensions.

codium --install-extension ms-python.python
codium --install-extension ms-toolsai.jupyter

If you get installation errors, make sure your VSCodium is properly configured to use Open VSX.

2. Install the Jupyter Extension from Open VSX Steps:

Open VSCodium.

Go to Extensions (Ctrl+Shift+X).

Paste this URL into the search bar: https://open-vsx.org/vscode/item?itemName=ms-toolsai.jupyter

Install the Jupyter extension and reload VSCodium. Alternative (Manual Installation): Download the .vsix file from Open VSX. In VSCodium, go to Extensions > ⋮ (More Actions) > Install from VSIX. Select the downloaded file and install. Post-Installation: Ensure Python and required packages (like pandas) are installed in your environment. Restart the debugger. The "View value in data viewer" feature should now work.

3. Use an external viewer as a workaround If the viewer doesn’t load, use the terminal to inspect or export the data:

print(df.head())
df.to_csv("debug_output.csv")  # then open in Excel or similar

4. Enable Microsoft Marketplace (Advanced) If you're okay with using the Microsoft marketplace, you can modify your settings.json:

"extensionsGallery": {
  "serviceUrl": "https://marketplace.visualstudio.com/_apis/public/gallery",
  "cacheUrl": "https://vscode.blob.core.windows.net/gallery/index",
  "itemUrl": "https://marketplace.visualstudio.com/items"
}

I did a little digging and the issue is that the Jupyter extension deprecated the existing data viewer in favour of a closed source "Data Wrangler" extension that's only available on the Microsoft marketplace. microsoft/vscode-jupyter#15486

Still the same issue here, python and jupyter (and pandas in my venv) installed, but also gets:

when I click yes and we search the extensions with "@tag:jupyterVariableViewers" nothing comes up

I also tried adding microsoft marketplace in my settings.json as hinted by https://github.com/VSCodium/vscodium/issues/2251#issuecomment-2797736268 but still not found (not sure the modif of the settings.json fixed anything).

Any way to fix this?
