Lol stupid posts like this make me question this place.

My brother who is a tax auditor at PWC uses spreadsheets all day long. Who are you again?

Do they use it as a source of truth or do they import that data in a spreadsheet to let the user make their own calculations?

Not the person you responded to but I'm genuinely curious.

Afaik Excel is wicked fast at math (can handle ginormous spreadsheets, some real magic under the hood), while correctly doing decimal based math (1/5 is 0.2 exactly, not some floating point monstrosity)

A yes PWC :-) That is what I would expect :-))

I just hope the divine powers of Luca Pacioli might help you, before is too late. A whole set of accounting bodies and real world disasters expressly advise against its use and spreadsheets in general.

You even have dedicated pages...

https://en.wikipedia.org/wiki/List_of_spreadsheet_mistakes

EuSPRIG Horror Stories - Spreadsheet mistakes

https://eusprig.org/research-info/horror-stories/

For example the (ICAEW) UK chartered accountants explicitly warn auditors. And research has shown that around 94% in these contexts contain errors:

"Errors in Operational Spreadsheets" - https://faculty.tuck.dartmouth.edu/images/uploads/faculty/se...

Also... Excel does not use exact decimal arithmetic. It stores numbers in IEEE-754 binary floating point, which cannot precisely represent many decimal values used in accounting. Microsoft documents this explicitly:

https://learn.microsoft.com/en-us/office/troubleshoot/excel/...

It also only preserves 15 significant digits and silently zeroes anything beyond that:

https://support.microsoft.com/en-us/office/excel-specificati...

So this means:

– decimal values are approximated

– rounding errors accumulate

– large financial values lose precision

– results depend on formula structure and rounding order

That alone disqualifies it as Accounting ledger. Historically you have lots of famous examples of bad outcomes of treating Excel as financial infrastructure...

The JPMorgan London Whale - $6B loss A flawed Excel risk model and copy paste errors understated risk and helped produce multi-billion losses. https://en.wikipedia.org/wiki/2012_JPMorgan_Chase_trading_lo...

TransAlta energy trading — $24M loss Simple spreadsheet row misalignment in bidding model cost aprox 10% of the company profit. https://www.lumeer.io/spreadsheet-for-project-management/

Fannie Mae - $1.3B reporting error wrong spreadsheet formula caused more than $1B accounting misstatement. https://www.theguardian.com/technology/2024/oct/28/microsoft... https://archive.is/w1cjj

Fidelity Magellan — $2.6B error Missing minus sign in a spreadsheet overstated capital gains by billions. https://en.wikipedia.org/wiki/List_of_spreadsheet_mistakes

Large audit firms also publish entire risk frameworks, ( and I am sure PWC does also...) explaining why uncontrolled spreadsheets are a major source of financial misstatement in the first place.

This entire site is full of idiots confidently spouting nonsense. Probably time to move on. "Don't use Excel for accounting" has to be the dumbest thing I've read in a year, even with all of the LLM bullshit going on.

And that's including the people this morning who are apparently excited for LLMs to file their taxes.

I've been having the same feelings lately, especially around the AI doomers coming in with some weird observations that make no sense. I usually don't comment, but seeing a lot of these types of overgeneralized responses.

'oh you do x? You don't do y? You're an idiot'

That's not productive.

"This entire site is full of idiots confidently spouting nonsense."

Too right - this goes for the arrogant geeks at the within the orgs of LLM producers who still havent displaced call center workers with their technology.

Comical stuff. Really is.

The lack of disconnect with what people actually do in jobs is absolutely breathtaking.

You don't really deserve a response, but even the idea that you could tell someone to not use Excel for accounting and seriously project that you know anything about how accounting works in the real world is hilarious.

You could think 500 random internet articles - it doesn't matter. The assertion is still ridiculous. You literally will not be able to get a job as an accountant without being able to use Excel. Don't be an idiot.

You can also link to hundreds of articles showing that dynamic types cause errors. People don't care, they still use them when it makes sense to use them. There is no better mainstream alternative for accounting than Excel right now, period.

Not a single reply on the technical and governance arguments?

I think we agree...this site is indeed full of idiots confidently spouting nonsense. :-)

		It's shocking and honestly pathetic. "Hey guys the software you use is not accurate" being met with such derision is how we regress as a society, not move forward.
