Welcome to the July 2026 update. New this month for Copilot in Excel: inline citations, synced connectors, Power BI grounding, brand and theme design skills, and support for workbooks with AutoSave turned off.
Also new this month, two frontier models are now available in Copilot in Excel: OpenAI's GPT-5.6 and Anthropic's Claude Opus 5. Optimized for knowledge work and stronger multi-step reasoning, GPT-5.6 helps Copilot work through more complex analysis and get from task to outcome with less manual assembly. Opus 5 helps work through complex analysis with higher-quality modeling and more polished workbooks. You can choose the model that best fits your work right from Copilot in Excel.
