Developers have intelligent assistants to debug code. Spreadsheet users don’t. When Excel breaks, most users see #N/A or #VALUE! but not the real cause. Vibe Excel is a desktop spreadsheet intelligence assistant for non-experts. It analyzes formulas, ranges, and data relationships to identify structural root causes and suggest safe fixes — not just error suppression. Local, private, and compatible with modern and legacy desktop Excel versions. Free during early access.
