+++ Claude gets Excel-native powers plus financial data connectors, because apparently the barrier to enterprise adoption was just proximity to spreadsheets and Bloomberg terminals. +++
"Key updates:
* **Excel Add-in:** Claude can now work directly inside Excel to analyze data and build models.
* **New Data Connectors:** Connects to real-time market data from sources like Moody's, LSEG (LSEpic), and Egnyte.
* **Agent Skills:** Comes with pre-built skills for complex tasks like crea..."
