IMHO same as previous month. Not much. Some usual improvements to web version, some new copilot AI.

For the latter in some way it’s cool for non advanced users but in others what would be their ability to check for complex formulas if there is no shortcomings in what copilot proposed or what they asked.

Summary from article :

Generating multiple formula columns, creating complex formula columns that span across multiple tables, and new ways to engage with Copilot in Excel are now available to Excel users on web and Windows. Copying and pasting improvements and sharing links to sheet views are also available in Excel for the web, and the ink to text pen is rolling out to Insiders running Excel for Windows.
