I haven't used POI in a long time, and I need to throw something
together pretty quickly to read specific data out of a somewhat
complicated spreadsheet.
In the spreadsheet, I'm going to need to read a value from each of many
merged cell blocks. When I view the sheet in Excel, the value is at
I have a spreadsheet with cells that have values like ≤ and ≥. I guess
these are unicode, but I'm not certain. When I read these values with
HSSFCell.getStringCellValue(), it seems to corrupt those characters. Is
there anything reasonable I can do about this?
Never mind. This isn't a POI problem. I'm having trouble using Writer to
write these characters out. It seems to corrupt these characters when I write
them out, or perhaps I'm getting confused about file encodings.

I'm reading a spreadsheet, and I have a cell and it's cellstyle, so I
can get the fillbg index. How do I tell what color that is? I can't
even figure it out by looking at the Constant Field Values link in the
javadoc. A cell that appears to be white shows a value of 65, and a
cell that appears
In my spreadsheet, I have a sample region of rows in a single column
where the first row has the value A, and the cell has a white
background. The rest of the cells in the column are grey, and are in a
single merged region. So, when I click on the A cell, it focuses on
just that cell. When I
If anyone's wondering, I gave up on this approach. It's more effective
to use merged regions.

I have an app using POI 2.5.1 that reads a spreadsheet and generates
some other files from it (in text files). I had it working with one

that is similar, but slightly different. I need to update the app to

Specifying -Xmx by itself doesn't do any good. You might try -Xmx1024m.

I noticed from a FAQ entry that this could happen if the spreadsheet
uses Excel features not supported by POI. Is there anything I can look
at in Excel that will give me a clue on this?

You might try the latest 3.0 RC1 at

I know that bugs related to macros were repaired in the last
couple of months.

I noticed that the javadoc for POI does not include the scratchpad
classes. Is this intentional? Is the Javadoc for these classes provide
somewhere else?

I'm trying to use 3.0rc2, and I'm trying to use the scratchpad jar for
the first time. I'm using JDK 1.4.2. When I try to compile my code
with Ant, I get the following:
bad class file:

Obviously, I was wrong to refer to this as the scratchpad jar. It's the
main poi jar.

Is the formula evaluation code in the scratchpad supposed to work?
I tried to evaluate a formula in a cell, but it gets the following
exception:
java.lang.NullPointerException
at
org.apache.poi.hssf.usermodel.HSSFFormulaEvaluator.internalEvaluate(HSSF
FormulaEvaluator.java:293)
Using 3.0rc2, the formula evaluator failed on a particular cell, with
the stacktrace following this. Before I file an issue for this, is this
expected to fail this way? Is there any workaround I can implement?
Error: Integer Expected
java.lang.RuntimeException: Cannot Parse, sorry : Integer
Never mind, we've changed the formula to something more reasonable, and
it's able to process it.

Perhaps you're looking to check whether the cell type is blank. Once
you have a HSSFCell object, call getCellType() and compare it against
HSSFCell.CELL_TYPE_BLANK.

I'm new at this also, but you should probably use the
org.apache.poi.hssf.usermodel.HSSFFormulaEvaluator class from the
