I felt I did not understand the issue but replied anyways.
However, check the SET NULL command in help. If ON it will allow you to
store a null value.
Also you can create a cursor with fields that accept null values thus:
create cursor blabla(number I null,desc C(10))
append blank
replace number with null, desc with 'null value'
browse
will show null in the number column and 'null value' in the desc column
Then, when you save the cursor as an excel file _perhaps_ you will have
a null value in the applicable cell (_this I did not try_)

Subject: Re: A Blank Value for a Number?
I'm not sure I understand your problem, but I often have to read an Excel file
and pass the data to a table. Sometimes there is no value in a cell that should
have a certain value (character or numeric)
Reading it line by line in those cases Excel sends a NULL value.
I just do something like this:
cFile = 'c:\exceldata\myexcelfile.xls'
this.oExcel=createobject("Excel.Application")
With this.oExcel
.Workbooks.Open("&cFile")
.Range("A27").Select
oRange = .Range("A27:L27")
Do while .t.
with oRange
cDescription = Nvl(Alltrim(.Columns[3].value),'')
etc., etc. && read more cells into ad hoc variables
endwith
oRange = oRange.Offset(1,0) && jump to next
line on Excel sheet
EndDo
and then it is a simple thing to replace the dbf DESCRIP field with cDescription
I re read your post and see that you want to blank certain cells automatically.
Following the above technique it should be an easy thing to do. Just look at my
example with the cDescription variable. The nvl function will give it a value
of '' if it contains a null value, or the actual value if it is not null

I know - it's a Crazy request. Trying to figure out the Easiest way to try and
do this - and hoping to Avoid having to do more complicated solutions like
Office Automation to manipulate an Excel file.
So - here's the deal. This system I work on - it outputs this Excel file. And,
in the past - if there are certain records that have a Zero in a particular
column - they would Manually wipe out the Zero - and also blank out several of
the other fields in that Row.
But, the new request is to make those things happen automatically during
process when the Excel file gets exported. So that they do NOT have to manually
blank out certain fields. But, of course, therein lies the problem. For the
other rows of data - this particular field is supposed to be a numeric value.
And, AFAIK - there really is NO Way to have a DBF or Cursor that has a Numeric
field - and yet have blank values in it.
As such, I suspect the answer is that this can't be done - to have a numeric
data field hold any kind of blank data. They even suggested just a Dash. But,
again - I figured it's not possible. However, I figured for the hell of it - I
would post here - in case someone had an interesting insight that I hadn't
thought of...
