@Dennis,
I agree that conforming to ODFF is first goal. I add comments and
attachment in https://issues.apache.org/ooo/show_bug.cgi?id=65221
From my understanding of ODFF, I give ODFF expect result for some formula
related with empty cell in the attachment(xls). If there is any mistake,
please comments.
Open this file in AOO3.4/LO3.5, 16 cases fail.
There are:
Criterion in COUNTIF/SUMIF
ODFF AOO3.4/LO3.5
criterion as "=" empty cell empty string cell
criterion as "<>" not empty cell not empty cell and not empty
string cell
criterion as "<>0" any cell except any cell except 0, not
including empty cell
value 0, including
empty cell
Criterion in criteria for database formula, such as DSUM, DCOUNT
ODFF AOO3.4/LO3.5
criterion is empty value 0 all cells
cell
criterion is empty empty string all cells
string
criterion as "=" empty cell empty cell and empty string cell
criterion as "<>" not empty cell not empty cell and not empty
string cell
Also AOO3.4/LO3.5 has self-consistent problem.
The different result for same criterion between COUNTIF/SUMIF and database
formulu(DCOUNT/DSUM). These criterion includes:
criterion is empty cell, criterion is empty string, criterion is "=",
criterion is "<>0"
While, open this file in Excel 2003, 8 cases fail.
There are:
Criterion in COUNTIF/SUMIF
ODFF Excel 2003
criterion is "" empty string cell empty string cell and empty
cell
criterion is empty empty string cell empty string cell and empty cell
string
Criterion in criteria for database formula, such as DSUM, DCOUNT
ODFF AOO3.4/LO3.5
criterion is empty value 0 all cells
cell
Also Excel 2003 has self-consistent problem.
The different result for same criterion between COUNTIF/SUMIF and database
formulu(DCOUNT/DSUM). These criterion includes:
criterion is empty cell, criterion is empty string
It seems Excel has better conformance for these test cases.
Conform to ODFF is very important. Compatible with Excel is also very
important, especially for some common used Excel scenario, such as
COUNTIF(<refrange>, "") to count all cells displayed as empty. Do we have
any chance to modify ODFF to solve this Excel user problem?

@Andrew,
See latest comments on https://issues.apache.org/ooo/show_bug.cgi?id=65221
I agree with orw that the first goal should be to align with OpenFormula,
and that is specific about the use of Criteria in SUMIF, COUNTIF, etc., as
you saw in section 4.11.8.
In the case that there needs to be further clarification in OpenFormula,
comments can be submitted to the ODF TC for Errata and/or improvements in
the next edition, ODF 1.3. OpenFormula was developed with cross-format
interoperability in mind and Microsoft participation was helpful for that.
User Guide documentation on these cases is probably also important.

Hi all,
There is an old bug i65221(
https://issues.apache.org/ooo/show_bug.cgi?id=65221). It is about
interoperability with Excel for SUMIF, COUNTIF, COUNTBLANK, DCOUNT,
DSUM,
... with empty cells and "" and ="" empty string criteria.

I am surprised that the ODF standard does not dictate how this should
be handled. I was under the impression that function behaviour in an ODF
document was well defined. I believe that Robert Weir is far more aware
of ODF type issues than I (since I have seen him mentioned by name on
similar topics) - not that I intend to unfairly pull him into this
discussion.
In Version 1.2 of the part-2 for OpenFormula, I don't see it obviously
spelled out, but I don't really have time to extensively pursue it.

4.7 Empty Cell
An empty cell is neither zero nor the empty string, and an empty cell
can be distinguished from cells containing values (including zero and
the empty string). An empty cell is not the same as an Error, in
particular, it is distinguishable from the Error #N/A (not available).
Moving on to section 4.8........
The definitions of specific operations and functions that allow
references as operands and parameters stipulate any particular
limitations there are on forms of references and how empty cells, when
permitted, are interpreted.
Now, on to 4.11.8, pretty clear here:
4.11.8 Criterion
A criterion is a single cell Reference, Number or Text. It is used in
comparisons with cell contents.
A reference to an empty cell is interpreted as the numeric value 0.
A matching expression can be:
A Number or Logical value. A matching cell content equals the Number or
Logical value.
A value beginning with a comparator (<, <=, =, >, >=, <>). 6.4.9
For =, if the value is empty it matches empty cells. 4.7
For <>, if the value is empty it matches non-empty cells.
For <>, if the value is not empty it matches any cell content except
the value, including empty cells.
Note: "=0" does not match empty cells.
For = and <>, if the value is not empty and can not be interpreted as a
Number type or one of its subtypes and the host-defined property
HOST-SEARCH-CRITERIA-MUST-APPLY-TO-WHOLE-CELL is true, comparison is
against the entire cell contents, if false, comparison is against any
subpart of the field that matches the criteria. For = and <>, if the
value is not empty and can not be interpreted as a Number type or one of
its subtypes 3.4 applies.
Other Text value. If the host-defined property
HOST-SEARCH-CRITERIA-MUST-APPLY-TO-WHOLE-CELL is true, the comparison is
against the entire cell contents, if false, comparison is against any
subpart of the field that matches the criteria.
