Problem when using JXL Formula like SUM() AVG() STDEV() returns #VALUE! when it refers values from another sheet
I want to populate some values in a sheet and then use jxl Formula to get the values from that sheet and write it to another sheet...
When I try to run this sample code
String filename = "C:\\input.xls";
WorkbookSettings ws = new WorkbookSettings();
ws.setLocale(new Locale("en", "EN"));
WritableWorkbook workbook =
Workbook.createWorkbook(new File(filename), ws);
WritableSheet s = workbook.createSheet("Input", 0);
WritableSheet s1 = workbook.createSheet("Output", 1);
s1.addCell(new Number(3, 0, 5));
s1.addCell(new Number(3, 1, 6));
s1.addCell(new Number(3, 2, 1));
s1.addCell(new Number(3, 3, 6));
s1.addCell(new Number(3, 4, 1));
Formula formula = new Formula(3,5,"AVERAGE(Output!D1:Output!D5)");
s.addCell(formula);
I am getting the last value in the AVG list has the output
=AVERAGE(Output!D5)
JAR Used : jxl 1.0.jar....

Solution tried :
1) Instead of giving it has a formula I gave it has label
Label label = new Label (3,5,"AVERAGE(Output!D1:Output!D5)");
I got the entire text in the cell and gave '=' before the cell.. It worked like a charm. But I want this to be done with JXL API
2) Changed the JAR to jxl 2.6.jar
Now I am getting #VALUE! when I try to run the same. The cell content is
=AVERAGE(Output!D1:Output!D5) but still I get #VALUE!.
JAR Used : jxl 2.6.jar
This error is getting solved only when I go to that cell and press tab key or F2 key.
Please provide some solution

It looks like excel is evaluating the formula in a strange way, hence why you are seeing #VALUE!
. To see why the formula is failing, click on the formula cell and then go to Tools > Formula Auditing > Evaluate Formula
. You will see that the steps are:
AVERAGE(Output!D1:Output!D5)
=AVERAGE(5:Output!D5)
=AVERAGE(5:1)
=AVERAGE(#VALUE!)
=#VALUE!
But when you execute F2+Enter
on the cell, you will see that Excel changes its execution plan and gets the right answer.
I'm afraid the only thing I can think of to fix this is to use a comma-separated list, instead of a range:
Formula formula = new Formula(3,5, "AVERAGE(Output!D1,Output!D2,Output!D3,Output!D4,Output!D5)");
You can fix this problem if you put in e.g. Z1 = "=Output!D1", Z2 = "=Output!D2"... and later you try AVERAGE(z1:z5) in your favorite cell
