I tried to get Claude to build me a spreadsheet last night. I was explicit in that I wanted an excel file.

It’s made one in the past for me with some errors, but a framework I could work with.

It created an “interactive artifact” that wouldn’t work in the browser or their apps. Gaslit me for 3 revisions of me asking why it wasn’t working.

Created a text file that it wanted me to save as a .csv to import into excel that failed hilariously.

When I asked it to convert the csv to an excel file it apologized and told me it was ready. No file to download.

I asked where the file was and it apologized again and told me it couldn’t actually do spreadsheets and at that point I was out of paid credits for 4 more hours.
