If that operation happens more than a couple of times a year, the organization should have figured out an Excel replacement a long time ago. One possibility is that a human is doing something to each of some significant portion of those rows, in which case more data entry should take place earlier and closer to the business. If that isn't the case, then just write a damn report already!
Actually there is one more possibility, that one or more goofballs in accounting just like to waste time "looking over the numbers and getting a feel for them". This generates lots of spurious questionably-motivated inquiries to business and IT people (who always blame the other party, when only accounting is to blame for their own vague feelings). In that case don't worry about fixing anything at the company, just get a different job somewhere else.
