TL;DR
GridScript.io lets you open Excel/CSV files, run JavaScript or Python scripts to transform the data, and export the result — all in your browser.
No backend. No install. Instant feedback.
Why I Built It
Developers constantly bounce between spreadsheets and code when working with data — cleaning CSVs, merging reports, converting formats.
I wanted a way to stay inside the browser and use the languages I already know (JavaScript and Python) to transform and visualize data.
That idea became Gridscript.io.
But it's also more than that, Gridscript offers access to Tensorflow.js and Scikt-learn allowing engineers to directly build AI/ML models.
Tech Stack
- Next.js – fast frontend framework
- AG Grid – Excel-like grid for editing and filtering
- Monaco Editor – same editor used in VS Code
- Client-side architecture – no data leaves your browser
- Undo/Redo system – safe experimentation
Example Workflow
- Create a New Pipeline
- Upload an Excel, JSON or CSV file
- Write a few lines of code in JS or Python
- Instantly see the grid update
- Export the result
context.data = context.data.filter(row => row.quantity > 10);
context.data.forEach(row => row.price = `\$${row.price.toFixed(2)}`);
Why Both Languages?
I didn’t want to force users into one ecosystem.
Web devs love JS; analysts live in Python.
Both deserve the same smooth experience.
GridScript makes that possible with a unified scripting interface.
Privacy by Design
Everything happens client-side — no data upload, no server storage.
Perfect for sensitive business files.
