Claude Sheets and Whiteboards (beta): how to create one, and what the beta cannot do yet

This is a short summary. The full guide, with every step and the limits, is on Kuponaut: https://kuponaut.com/blog/claude-sheets-whiteboards-beta-how-to-use/

On 10 November 2026 Anthropic added three work surfaces to Claude: Whiteboards for planning on a shared board, Sheets for spreadsheets that Claude builds and edits with you, and Claude Data for dashboards on company data. Whiteboards and Sheets are in beta; Claude Data, the renamed Claude Dashboards, is generally available. All three need a paid plan, and the cheapest is Pro at $20 a month.

How to create a Claude Sheet, in short

1. Start one. Ask Claude for a sheet in any chat (a tracker, a budget, a forecast), or open the Artifacts tab and choose the Sheets tile.
2. Bring in data. Import a CSV file, import from Google Sheets or Excel, or paste copied cells. Imports are one-time copies, so the sheet does not stay linked to the original file.
3. Ask for changes in plain language. Add a column, highlight overdue rows, add a chart. Formulas stay visible in the cells, so you can check them.
4. Check the work. Each change Claude makes is outlined as it is applied, and version history lets you go back to an earlier version.
5. Share or export. A sheet is private until you click Share. You can download it as .xlsx or CSV.

One limit worth knowing before you import: a sheet with 20 columns reaches the 100,000-cell limit at 5,000 rows (our arithmetic).
