About whether Claude for Excel can be trusted with messy real-world spreadsheets.

Not really. Take for example:

item, date, price

abc, 01/01/2023, $30

cde, 02/01/2023, $40

... 100k rows ...

subtotal. $1000

def, 03/01,2023, $20

"Hey Claude, what's the total from this file?

grep for headers

"Ah, I see column 3 is the price value"

SUM(C2:C) -> $2020

"Great! I found your total!"

If you can find me an example of tech that can solve this at scale on large, diverse Excel formats, then I'll concede, but I haven't found something actually trustworthy for important data sets

AI reliably computes correct totals on large, diverse Excel files at scale, e.g. without double-counting embedded subtotal rows.
