ReoGrid Studio Released — Build Online Spreadsheets in Natural Language, with MCP for AI Agents

UNVELL Inc. has released ReoGrid Studio (studio.reogrid.net), a browser-hosted online spreadsheet.

You can author and edit sheets in plain language — and, most importantly, AI agents can publish their analyzed data as real, navigable spreadsheets through a public MCP endpoint.

■ Background

Most AI tools today output text — even after analyzing data, the result lands in chat as a markdown table that you must manually paste into a real spreadsheet to act on. ReoGrid Studio closes that gap.

■ Two roles

Natural-language authoring: type what you want and a spreadsheet renders live. Iterate via chat, then hit Publish to mint a short URL you can share.

AI visualization endpoint: any AI that has analyzed data can publish it as a real spreadsheet via MCP (Model Context Protocol) and hand the user a short URL. Works with Claude Code, Claude Desktop, Cursor, and the Anthropic API.

■ Supported features

The wire format is the same ReoGridJsonDocument as ReoGrid Web (@reogrid/pro), supporting formulas, styles, merges, borders, frozen rows/columns, cell types, conditional formatting, rich text, and more. The public viewer is interactive read-only.

■ Pricing

Completely free today, with no login required (30 publishes per hour per IP). A commercial plan with higher quotas and team features is on the roadmap.
