HOW IT WORKS
From Excel workbook to live web app with River and Claude
THE PROBLEM
Why publishing a model is harder than it looks
A simple way to publish a model is to extract its output data and embed it in a static web page.
However if you want the visitor to update the input parameters and see the output change, you have to precalculate all the possible outputs. When the number of parameters grows, this becomes a slow, expensive, and error-prone process.
The real solution is a dynamic website, where the model runs live in the backend. But that means recoding everything in Python or another language, requiring a developer, introducing trust issues, and disconnecting you from the model you built.
01
Static files break fast
Pre-generating outputs for every input combination becomes prohibitive as complexity grows. Any model update means starting over.
02
Recoding introduces risk
Translating Excel logic into Python requires a developer and creates an unaudited, disconnected copy of your model.
03
AI alone cannot be trusted
Code-generating AI speeds up recoding, but you lose control. Complex models carry too much risk to be blindly transcribed.
THE SOLUTION
Why River changes this
River models are not locked inside Excel. When you're ready to publish, River exports your model as a self-contained folder with a SQL script and all inputs, a format designed to run directly as a backend. No recoding. No handoff to a developer.
From there, you use Claude to customize River's dynamic site template and build a front-end tailored to your use case. AI handles the interface. River guarantees the calculation layer.
The logic that passed your QA process is the exact logic that runs on the website. The power of AI with the trust of River.
Trust
Your model, unchanged
The SQL export is a byte-for-byte equivalent of your River model. No translation, no interpretation, no risk of silent errors.
Speed
Publish in minutes
Export, drop into the River site template, and let Claude customize the front-end. No engineering sprint required.
Agility
Update without friction
Modify the model in Excel, re-export, and republish. Iterations are as fast as your analysis, not your dev team's schedule.
