Describe the change you want in plain English, like "drop rows where status is empty" or "split full name into first and last," and a local AI writes the transformation and runs it on your data. The model (Gemma via WebGPU) and your file both stay on your machine, so even messy internal exports never touch a server. Every step is undoable, and you can read the generated code before applying it. Works on CSV and Excel files, including large ones that get processed in chunks so the tab stays responsive.
No. The Gemma model runs in your browser through WebGPU, and your file is parsed and edited locally. Nothing leaves your device, so it works with confidential data and even offline once the model is cached.
Yes. The tool shows the JavaScript transformation it generated for each instruction. You review it, apply it, and undo it if the result isn't what you wanted.
Large CSVs are parsed and transformed in chunks inside a web worker, so files with hundreds of thousands of rows keep working without freezing the browser tab.
Every tool runs entirely in your browser. Files are never uploaded — 100% private and free.
