Sheet analyzer

Sheet analyzer is a lightweight browser extension built for people who spend their day inside Google Sheets and want quick answers without writing formulas or pivot tables. Instead of configuring API keys or connecting elaborate data pipelines, you install the extension, paste the URL of a Google Sheet, and start asking questions. The extension reads the sheet contents and hands them to Google's Gemini large language model, which returns written answers about the data.

The tool is deliberately simple. It targets the everyday spreadsheet tasks that slow people down: finding a specific value, summarizing a column, understanding what a range of numbers means, or getting a plain-language read on a dataset before deciding what to do next. Because it relies on Gemini for the reasoning step, the quality of answers tracks the underlying model, and Google Sheets must be accessible to the browser session for the extension to read it.

Sheet analyzer is distributed through the Chrome Web Store as a free utility with a small install footprint and no account requirement. It has a modest but real user base and a straightforward privacy posture: the developer states that data is not sold to third parties and is not used for purposes unrelated to the extension's core functionality. It is best thought of as a convenience layer for casual spreadsheet analysis rather than a replacement for a full BI platform.
