24 alternatives to Modeleon – Python DSL that compiles to live Excel formulas
Hi HN. Modeleon is an open-source Python DSL for financial models. You write models in Python with named variables and operator-overloaded arithmetic, and it compiles to a real .xlsx with live formulas — not values, but formulas like =B4*B5 that the CFO can audit in Excel. The architectural bet is "model is the source of truth, spreadsheet is one rendering." We have a Walker/Renderer split so the same model can target Excel today and other backends later. We've been building this for finance + Python developers (CFA candidates with Python skills, FP&A analysts who automate). It's…

In a popular post today[1] the title claims "VM in Google Sheets", but it's actually in Google Script, which is basically Javascript and not an interesting technical accomplishment (definitely a useful educational tool, though). Disappointed, I set out to fix it. Voila! https://docs.google.com/spreadsheets/d/1g3-FZBnkDuLqFYOmk457... A Brainfk interpreter in pure Google Sheets formulas. The hard part was parentheses matching, so I think other VMs would be even easier. [1] https://news.ycombinator.com/item?id=14701460

We (me and @aarondia) built a tool to help you turn psuedo-software Excel files into real-software Python. Ideally, Pyoneer helps you automate your manual Excel processes. You can try it today here: https://pyoneer.ai. How it works: 1. You upload an Excel file 2. We statically parse the Excel file and build a dependency graph of all the cells, tables, formulas, and pivots. 3. We do a graph traversal, and translate nodes as we hit them. We use OpenAI APIs to translate formulas. There’s a bunch of extra work here — because even with the best prompt engineering a fella like me can do,…

Hi, I am David Kircos. The Founder of Quadratic (https://QuadraticHQ.com), an open-source spreadsheet application that supports Python, SQL (coming soon), AI Prompts, and classic Formulas. Unlike other spreadsheets, Quadratic has an infinite canvas (like Figma). As a result, you can pinch and zoom to navigate large data sets, and everything renders smoothly at 60fps. Our vision is to build a place where your team can collaborate on data analysis. You can write Python, AI Prompts, and Formulas in one spreadsheet feeding each other data and updating automatically. Quadratic is built…

Dear HN, I am Riwaj, the cofounder of dstack.ai (https://github.com/dstackai). A few months ago, we built an online service that allows users to publish data visualizations from Python or R. The idea was to build a tool that did not require additional programming or front-end development for publishing data visualizations. Such a code can be invoked from either Jupyter notebook, RMarkdown, Python, or R scripts. Once the data is pushed, it can be accessed via a browser. Open-sourcing dstack: During our customer discovery phase, we realized that dstack.ai should integrate a lot…

We’re Robin, Louis, and Thomas. Pipelex is a DSL and a Python runtime for repeatable AI workflows. Think Dockerfile/SQL for multi-step LLM pipelines: you declare steps and interfaces; any model/provider can fill them. Why this instead of yet another workflow builder? - Declarative, not glue code: you state what to do; the runtime figures out how. - Agent-first: each step carries natural-language context (purpose, inputs/outputs with meaning) so LLMs can follow, audit, and optimize. Our MCP server enables agents to run pipelines but also to build new pipelines on demand. - Open…

We built what we're calling "operational spreadsheets" – spreadsheets that can actually execute actions across external systems, not just calculate and display data. The core idea: spreadsheets have been passive tools for 40 years. You put data in, formulas process it, you export it, manually move it somewhere else, repeat. We added bidirectional API integration with natural language commands, so the spreadsheet itself can send emails, update databases, orchestrate workflows across services – autonomously. Think of it as the evolution from VisiCalc → Excel → Google Sheets (multi-user) →…

Hi HN! I’m Eoin, founder of Sourcetable (https://sourcetable.com). Sourcetable is an AI-native spreadsheet that syncs with all your data. Users pair with an AI copilot that helps them do their spreadsheet work, as well as more database-centric analysis and SQL. Soucetable syncs with databases including Postgres, MySQL, and MongoDB, and over 100+ business applications including Stripe, Zendesk, Hubspot, Quickbooks and Google Analytics. That data is available in a spreadsheet, and any models you build automatically update in near-real-time as new data flows in. The core primitives…

Probly was built to reduce context-switching between spreadsheet applications, Python notebooks, and AI tools. It’s a simple spreadsheet that lets you talk to your data. Need pandas analysis? Just ask in plain English, and the code runs right in your browser. Want a chart? Just ask. While there are tools available in this space like TheBricks, Probly is a minimalist, open-source solution built with React, TypeScript, Next.js, Handsontable, Hyperformula, Apache Echarts, OpenAI, and Pyodide. It's still a work in progress, but it's already useful for my daily tasks.

Hey HN! Been a minute. We launched Mito here last year (https://news.ycombinator.com/item?id=32723766). Mito is a spreadsheet that generates Python code as you edit it. We've spent the past three years trying to lower the startup cost to use Python for data work. In doing so, we’ve been thrust into the middle of many Python transition processes at larger enterprises, and we’ve seen up-close how non-technical folks interact with generated code. The Mito AI chatbot lives inside of the Mito spreadsheet (https://www.trymito.io/>. The obvious benefit of this is that…

OpenSheet▲86Hi folks. I've been doing some experiments on how LLMs could get more handy in the day to day of working with files (CSV, Parquet, etc). Earlier last year, I built https://datakit.page and evolved it over and over into an all in-browser experience with help of duckdb-wasm. Got loads of feedbacks and I think it turned into a good shape with being an adhoc local data studio, but I kept hearing two main things/issues: Why can't the AI also change cells in the file we give to it? Why can't we modify this grid ourselves? So besides the whole READ and text-to-SQL flows, what seemed…
