Frockly – A visual editor for understanding complex Excel formulas
I built a visual editor that represents Excel formulas as blocks, making it easier to inspect, refactor, and reason about complex formulas structurally. Frockly is not an Excel replacement. It focuses on understanding and refactoring formulas before bringing them back to Excel.

In plain words
Frockly is a visual editor that displays Excel formulas as blocks, helping users inspect, refactor, and understand complex formulas structurally. Designed for spreadsheet professionals who work with intricate formulas, it breaks down formula logic into visual components for easier comprehension and modification. The tool is not intended to replace Excel but rather to serve as a companion for analyzing and improving formulas before returning them to spreadsheets.
