Can Jarvis Read a Spreadsheet on My Screen?
What can I ask about cells?
Yes: Jarvis (getjarvis.eu) is a screen-aware desktop AI assistant that reads the open sheet and answers questions about it. Press Cmd+/ on macOS or Ctrl+/ on Windows over Excel or Google Sheets and ask what a column means, what a total should be, or which formula to use. Nothing has to be pasted into a chat window. Press Cmd+/ (macOS) or Ctrl+/ (Windows) over the sheet and ask "what's the total of column D?" or "write a formula to flag overdue rows." Jarvis captures the visible cells and routes them to frontier models from Anthropic, OpenAI, or Google to explain, calculate, or draft the exact formula in Excel or Sheets syntax. With the Google Sheets connector authorized it can go further — reading or writing the actual file rather than just the visible screen. It reads what is on screen for any spreadsheet app, even desktop Excel. It never trains on your data. A free plan (40 requests/week); the Pro plan is $16/month.

When you trigger the floating bar over a spreadsheet, Jarvis captures the cells currently on screen — headers, values, and formatting cues. From that it can summarize what the sheet contains, spot the column that does not add up, explain a gnarly nested formula already in a cell, or write a new one in the right dialect: VLOOKUP versus XLOOKUP for Excel, ARRAYFORMULA for Google Sheets. A frontier model is reliable at constructing and explaining formulas; a faster model is quick for routine sums, averages, and conditional logic. Because it reads the screen, it works in desktop Excel, Numbers, or any web grid, not only tools it integrates with.
The visible screen is a snapshot; sometimes you need the whole file. With the Google Sheets connector authorized, Jarvis can read entire ranges, append rows, or update cells directly — useful when the data runs past what is on screen or when you want it to write results back. It can also pull numbers from a sheet into a Notion page, a Slack update, or a Gmail draft. Persistent, user-controlled memory keeps context about a recurring sheet across sessions. OAuth tokens are encrypted with AES-256-GCM on GDPR-aligned infrastructure servers, and your spreadsheet data is never used to train any model.
