alt Hacker News> On one hand, you have Microsoft's (awful) Copilot integration for Excel (in fairness, the Gemini integration in Google Sheets is also bad). So you can imagine financial directors trying to use it and it making a complete mess of the most simple tasks and never touching it again.
Microsoft has spent 30 years designing the most contrived XML-based format for Excel/Word/Powerpoint documents, so that it cannot be parsed except by very complicated bespoke applications with hundreds of developers involved.
Now, it's impossible to export any of those documents into plain text that an LLM can understand, and Microsoft Copilot literally doesn't work no matter how much money they throw at it. My company is now migrating Word documents to Markdown because they're seeing how powerful AI is.
This is karmic justice imo.

Tim Berners-Lee thought pages would become machine-readable long ago, with "obvious" benefits, and that idea partly drove XML, RDF and HTML 5. Now the benefit of doing so seems even bigger (but are they?), and the time spent making existing documents AI readable seems to keep growing.
Totally agree, though ironically Claude code works way better with Excel than I expected.
I even tried telling Copilot to convert each sheet to a CSV on one attempt THEN do calculations. It just ignored it and failed miserably, ironically outputting me a list of files that it should have made, along with the broken python script. I found this very amusing.
