SheetChat reads your workbook, gives Claude read-only tools to query the real cells, and answers in plain language — never guessing at numbers. Explore formula dependencies, change inputs, and connect another workbook through explicit cell links to see how the results change.
Drop in an Excel workbook (.xlsx or .xlsm). Your file is encrypted at rest, processed in memory, and deleted as soon as you finish — no account needed.
Totals, lookups, filters, “what drives this number?” Claude calls read-only tools (list sheets, read ranges, aggregate, evaluate formulas) so every answer cites the actual cells.
Change a value or formula, or link an output from another workbook. Compare before-and-after results and follow the dependency network. Unsupported calculations are clearly flagged.
A knowledge graph maps how every value connects to every other. Each node is a value and each link shows what feeds into what, so a flat list of numbers becomes a clear map of cause and effect. Start from any point and the graph fans out to everything behind it — each step further back a distinct, vibrant colour — letting you see at a glance what drives a result and trace it all the way to its origins. Drag to explore, scroll to zoom, and hover any node to pop a flag with its detail.
Each answer or impact analysis uses 1 credit(s). Uploads and dependency maps are free. Larger packs include bonus credits.
