Thanks for your reply and for the articles you linked to – especially
the last one is very interesting. I have been aware of that but not so
As I think you are very cunny both on spreadsheets and how to use them
and also the mathematics, I am not able to argue.
But I am sure you know what I meant when I said that a spreadsheet is
‘totally’ worthless if you cannot trust it, if it -- the program, its
features or functions -- does not work (behave) as supposed.
As an engineer I have been working with MSExcel since late 1980 and have
since 10 years successively began to use OO/LO.
I’ve always tried to crosscheck important calculations and with
calculation processes start with some few (random or logical) sample
data and/or manual calcs to be sure that the formulas (& combinations
of) work OK.
Whatever people say about Microsoft, I must say that I have never
experienced any problems caused by the program MSExcel itself (perhaps
I’ve been lucky) – all my problems have been caused by my typos or my
bad planning of the calculation process.
But, especially with LibreOffice/Calc I have experienced issues that
clearly depend on LO as a program and have caused me a lot of extra
doings – the last couple of years LO has become better.
Regarding the articles. If the programming of the "very big" programs
is purchased from a "third party" where the programmer -- the person --
does not have no own knowledge (understanding) about the customer's
process, then it is an unavoidable necessity that there will be flaws
and serious issues -- regarless of branch.
Anyhow, the fact is that Microsoft has a 90 percent market share and
every MSO suite includes MSExcel.
Above this are e.g. AOO/OO/LOwith roughly 2 mega spreadsheet users and
That means that quite a lot of – some very important -- calculations are
globally done with these MSO&AOO&OO&LO (..etc..) spreadsheets.
If the spreadsheets are that unreliable as these articles (and you)
explain, should it not then be good - if not a necessity – to warn about
it? Experts and “nerds” can manage but not ordinary users like me.
I like LibreOffice and respect its intensions and thus I want it to be
If LO really wants to increase its market share – to beat MSO, a benefit
for all users – then it has to eliminate every possible cause of
problems especially for the ‘ordinary user’ -- even the small ones like
that sorting issue.
The ordinary user selects a range and pushes the sort button -- if the
sort does not behave as expected, and there is no explanation why or how
and the help is too difficult to find -- then he/she considers this a
Too many problems is not good for LO.
It is the mass of ‘ordinary users’ that build most of the MSO’s market
The main and final responsibility lies – not on the (unpaid) programmer
-- but on the controlling team in the LO organization.
It is better to fix problems at a stage of planning and production than
after a global distribution(ref. to Quality Management Systems).

It's perhaps worth a reminder that, in the sense that you mean it,
spreadsheets can never be "trusted". Since much of their essential
functionality is hidden (formulae, formatting, significant options)
and they are untestable, you should never rely on the results of a
spreadsheet. Your judgement, then (but not mine) is that spreadsheet
programs generally are "totally worthless".
See, for example:
"I will happily use a spreadsheet to estimate the grades of my
students, my retirement savings, or how much tax I paid last year… but
I will not use Microsoft Excel to run a bank or to compute the
trajectory of the space shuttle. Spreadsheets are convenient but error
"But while Excel the program is reasonably robust, the spreadsheets
that people create with Excel are incredibly fragile."
"Among those who study spreadsheet use, it is widely accepted that
errors are prevalent in operational spreadsheets and that errors can
lead to poor decisions and cost millions of dollars."
"Panko summarized this literature by reporting that 94% of
spreadsheets have errors, with an average cell error rate of 5.2%."
