ExcelMaster
An AI agent inside Windows Excel for formulas, VBA, Python, charts, and data cleanup.
About ExcelMaster
ExcelMaster is an AI agent that works inside Microsoft Excel on Windows. It accepts task descriptions and can write formulas, generate and run VBA, execute Python, build charts, and clean spreadsheet data while showing its actions in real time. Formula work can use spreadsheet structure, headers, cell references, and cross-sheet context, with multi-turn dialogue for refining a result or explaining an existing formula. Its VBA assistant can generate, debug, refactor, and execute macros, including conditional data transfers and dynamic reports. Cell AI handles in-cell jobs such as classification, keyword extraction, format conversion, sentiment analysis, and translation, including batch processing. The product is suited to people who want spreadsheet automation without manually composing every formula or macro. Adoption is narrower for teams outside Windows Excel, and autonomous changes still require users to review workbook results. Access uses a paid subscription model, and checkout can associate a purchase with the email entered during payment.
Best for
Best use cases
A workbook needs formulas that reference headers, cell relationships, and data stored across several sheets.
A recurring report requires conditional data transfers, refreshed calculations, and chart creation in Excel.
A large column of text needs batch classification, keyword extraction, sentiment analysis, or translation.
Compare before choosing
