The most immediately useful thing Claude does in Excel is let you ask questions in plain English. Instead of building a pivot and three formulas, you ask, and it reads the range, computes, and answers. Done well, it changes how fast an analyst can interrogate a dataset.

But a spreadsheet only knows what you've pasted into it. ChatFin extends the same conversational experience to your live ERP — so the question is answered from the source of truth, with the number traceable back to it.

Setting It Up Well in Excel

Structure the data: clean headers, consistent types, and labeled ranges so Claude interprets the sheet correctly.
Give context in the prompt: state the period, the unit, and what 'good' looks like — 'compare actual vs budget for Q2, in USD thousands.'
Ask layered questions: start broad ('what moved?'), then drill ('why did marketing spend spike?').
Always review: treat the answer as a fast first pass and validate the number before it leaves your desk.

The Limit: The Sheet Isn't the Ledger

Conversational analysis in Excel is bounded by what's in the workbook. If the data is a stale export, the answer is stale. If the question needs live AP aging or today's cash position, the sheet can't help — and re-exporting on every question defeats the point.

"Claude answers questions about your spreadsheet. ChatFin answers questions about your ledger — live, and traceable to the source."

ChatFin connects to your ERP and lets finance teams ask questions of live data in natural language: 'What's our AP over 60 days by entity?' or 'How did gross margin trend this quarter?' — answered from the system of record, with the underlying transactions one click away, under a ledger-tuned memory layer and full audit trail.
