What is FileBender?

FileBender is a browser-based tool for building visual data transformation flows. You connect processing nodes on a canvas — input nodes that read files, transform nodes that filter, reshape, or compute new data, and output nodes that produce results — and FileBender executes them in order.

Key Concepts

Flows are directed graphs of nodes. Data flows left to right through connected nodes. Each node processes the data it receives and passes the result downstream.

Transforms are the operations that nodes perform: filtering rows, renaming columns, converting currencies, computing new values, aggregating groups, and more. Each transform has a configuration panel where you set its parameters.

Privacy by default. All processing happens in your browser. Your data never leaves your device unless a specific transform explicitly requires an external service — and those transforms are clearly marked with a privacy badge.

How It Works

1. Add input nodes to load your CSV, JSON, or Excel files.
2. Connect transform nodes to filter, reshape, or enrich your data.
3. Preview results at any point in the flow — click a node to see its output.
4. Add output nodes to export the result as CSV, JSON, or Excel.

The flow executes automatically as you build it. Change a parameter and every downstream node re-runs with the updated configuration.
