I just used Claude to edit an Excel spreadsheet. It pulled data from cells, modified formulas, adjusted formatting, and added a new sheet. Most amazing is that Claude did all this without ever opening Excel. I just pointed it to the .xlsx file, told it what I needed, and it handed back the modified file thirty seconds later.
Watching Claude work with that file directly, without needing Excel, blew my mind. It made me realize that I need to rethink a couple things in my mental roadmap of how AI will impact the future of EUC and enterprise IT.
