This sounds interesting! Do you have a specific example by any chance or blog post/doc references?

I tend to agree. SQL may have been harder to write in the past (worse autocomplete than pandas/polars), but now that AI is writing the code, SQL is usually much easier to read. So DuckDB is another interesting alternative to pandas.

Funny enough, I received a marketing email from GitHub during the outage with the following subject: "What if every pull request you started actually shipped"

Pyodide 314.0 is already available in xlwings Lite (the Python in Excel alternative you actually wanted).

DuckDB also runs in Excel, by the way, via the free xlwings Lite add-in that you can install from the add-in store. It’s using the Python package and allows to write scripts, custom functions, as well as use a Jupyter-like notebook workflow.

Pyodide powers xlwings Lite, a free Excel add-in that you can install from Excel’s add-in store with a single click. It outperforms Microsoft’s official Python in Excel solution in every coceivable way: price, privacy, speed, can install packages, can access the internet, can access local files, doesn’t have a usage quota, can automate Excel and create native UDFs.

Have you tried the CSP build of AlpineJS? It takes the code out of the template into a proper JS file, no unsafe-eval. Isn't state management mostly handled on the backend when you use AlpineJS?

I am not a random user, but the creator. The dependencies are managed via standard requirements.txt file, which is stored in the Excel workbook itself. When you open xlwings Lite with the workbook, the dependencies are installed from either PyPI or Pyodide's own repository (after the first download from the browser's cache).

Direct db queries are indeed a restriction of Wasm/Pyodide, but there are more and more databases offering a HTTP layer. For example, Supabase has this built-in via PostgREST. For Oracle, there is Oracle REST Data Services (ORDS). Ultimately, you can also build your own little proxy server, although that's a little bit more work, but might still be worth it for company-internal use.

No, this is for Excel only, but it does work with the free online version of Excel. I think LibreOffice has support for Python via PyOO.

SQLookup is an Excel add-in that gives you access to the SQLOOKUP function. The SQLOOKUP function allows you to query data in your Excel workbook using SQL (SQLite dialect). The add-in is free and works with Excel on Windows, macOS, and web. It can be installed via the add-in store.

So basically it’s free for 1 day per month (I only use chat).

It's exactly why I built xlwings, to replace VBA with Python. Python in Excel instead is a competitor to the Excel formula language.

No offense taken, and happy that xlwings was an inspiration for creating Row Zero! I don't really buy the security issues though for being the reason for switching from Excel to Row Zero. Yes, Excel has security issues, but so does the cloud, but at least the issues with Excel can be dealt with: disable VBA macros on a company level, run Excel on airgapped computers, etc. Promising that your cloud won't be hacked or is unintentionally leaking information is impossible, no matter how much auditing and certification you're going through. The relatively recent addition of xlwings Server fixes pretty much all of the issues you encountered in your previous company: user don't need a local installation of Python, but the Office admin just pushes an Office.js add-in to them and their done. No sensitive credentials etc. are required to be stored on the end-users computer or spreadsheet either as you can take advantage of SSO and can manage user roles on Microsoft Entra ID (that companies are using already anyways).

As the author of said second class add-in, let me just guess that your most popular feature request was adding the "Import from xlsx" functionality...which describes the whole issue: it's always Excel + something, never something instead of Excel.

xlwings is a competitor to VBA rather than openpyxl: openpyxl can read and write the Excel file on disk, without involving the Excel application. xlwings is all about automating the Excel application, and write macros and custom functions in Python.

Hi all, I am Felix, the author of the post. I just wanted to reiterate that this post was mainly meant as a summary of my GitHub issues I opened with them. So it should really be seen as a feedback to help them improve the product. Python in Excel currently covers a completely different use-case than xlwings, but Python in Excel inspired me to finally look into WASM and PyScript, which is an awesome product.
