ChatGPT for Excel is an add-in that enables users to build, analyze, and update spreadsheets directly within Microsoft Excel using natural language commands. It allows users to create formatted sheets with formulas included, edit existing workbooks, and get insights from data without switching between different tools.

The product can build spreadsheets from scratch based on descriptions, analyze data across multiple tabs, understand and explain formulas, find and fix errors, spot patterns in data, and update workbooks in real time. It preserves existing formulas and formatting while making changes, and can clean up sheets by standardizing formatting, fixing inconsistent labels, and removing duplicates.

ChatGPT explains what it's doing step by step, links answers to the specific cells it references and updates, and asks for permission before making changes to the workbook. This allows users to verify each step and revert edits if needed, providing transparency and control over the automation process.

Benefits include faster spreadsheet creation, easier data analysis, error detection and correction, and streamlined workflow without tool switching. Use cases include creating personal expense trackers, analyzing spending patterns, grouping survey responses by theme, building project trackers, summarizing trends across multiple tabs, cleaning up messy sheets, explaining complex formulas, and updating tables with new assumptions.

The product is designed for Excel users who need to work with spreadsheets, including those creating financial models, analyzing business data, managing projects, and processing survey results. It integrates directly with Excel as an add-in and requires a ChatGPT Plus, Pro, Business, Enterprise, Edu, or ChatGPT for Teachers plan.
