SheetChat

Chat with your spreadsheets

Upload an Excel workbook, view your data right in the browser, and ask questions in plain English. Every answer is grounded in your actual cells — and we map how your formulas connect. No sign-up, no subscription.

How it works

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.

1

Upload

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.

2

Ask in plain English

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.

3

Evaluate the impact

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.

The knowledge graph

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.
