Spreadsheets as a System Dynamics Language: Unlocking Model Translation with AI

Spreadsheets are everywhere. Yet we rarely think of them as modeling languages.

In this presentation, I share a core idea that has been shaping my recent work:

👉 When rigorously structured, spreadsheets already encode stocks, flows, variables, parameters, and causal relationships.

In that sense, they can be understood as a Domain-Specific Language (DSL) for System Dynamics.

Building on this perspective, I explore how Large Language Models (LLMs) can act not as black boxes, but as reliable semantic translators, converting structured spreadsheets into formal System Dynamics models - while preserving structure, meaning, and traceability.

This is not just a technical contribution. It has broader implications for:

  • communication among system modelers,

  • model reproducibility and auditability,

  • education,

  • and dialogue between research, policy, and practice.

📎 Here is the presentation e here is the spreadsheet with original data.

I would be very interested in hearing feedback, critiques, and related experiences.

This feels like an early step toward a future in which models can truly “talk” to each other, regardless of their original language.

Here we have a basic SEIR model and we will investigate what changes would be appropriate for modelling the 2019 Coronavirus

Success to the successful archetype represents two reinforcing structures which may be in a delicate balance though as soon as one gains a small advantage the resource allocation favors the more successful and the result is then rapidly skewed in the direction of the more successful. See also Archetypes.
