I am using Apache poi3.5 and java
1.6 for my application. here, i have one problem using formula...
my Cell has formula(sheet2!C10) and the data inside this cell is String type...How to access that cell also want to display the formula.
my Cell has formula(sheet2!C11) and the data inside this cell is number type...How to access that cell also want to display the formula.
my Cell has formula(sheet2!C10) and the data inside this cell is Date type...How to access that cell and also want to display the formula.
For any formula cell, using poi3.8.
Workbook xlsWorkbook = null;
Cell cell = null;
FormulaEvaluator formulaEval = xlsWorkbook.getCreationHelper().createFormulaEvaluator();
String value=formulaEval.evaluate(cell).formatAsString();
System.out.println("Formula Cell value :" + org.apache.poi.ss.usermodel.DataFormatter dataFormatter.formatCellValue(cell, formulaEvaluator));
it will return the formula cell value as a string...

My formula is as follows:
=(CONCAT("=RSLINX|PLC1!",B3)
B3 = VarName1
The goal is to use the RSLINX function with the contents of a changing cell (B3)
I have also tried putting "=RSLINX|PLC1!" in it's own cell to reference as a string, as well as the following formula:
=INDIRECT(CONCAT("=RSLINX|PLC1",B3))
The objective is that B3 can change to a different cell (B4, B5, etc.) so that I can evaluate many different tags quickly, as the only way I've had the RSLINX function work is by manually typing in a correct tag name.
Resolved. I had to use the original formula:
=(CONCAT("=RSLINX|PLC1!",B3)
For all desired tags, then copy it and use "Paste Value" and Search & Replace all "RSLINX" with "=RSLINX" in the new columns.
Is there any way to calculate or is there any built-in API to get the current Cell position of an Excel sheet using Apache Poi??
Like A10 or F61 or AG34 or BK567 etc.
Note: I'm using poi3.9.jar. Thanks in advance. It would be preferable if there's a built-in api.
I need this cell position because, I want to use the below Formula to set value.
Formula is : cell.setCellFormula("G16/F16*100");
If you have the Apache POI Cell object to hand, you can call cell.getAddress() to get a CellAddress object.
From that, you can cell formatAsString to get the cell's address eg A1
int colNum = 2; // eg
Cell cell = row.getCell(colNum);
CellAddress addr = cell.getAddress();
String asExcel = addr.formatAsString(); // eg C3
so to give some context, I have an application running where I have written code where basically, on a button press:-
A new sheet is created
The columns "A:L" in the new sheet are conditionally formatted
The condition is If any cell in column A has a value then that cell color is red. Similarly, a different color condition for every column
To achieve this, I wrote the following code snippet in my Sub:
Dim condA As FormatCondition
Set condA = Range("A5:A500").FormatConditions.Add(Type:=xlCellValue, Operator:=xlNotEqual, Formula1:="")
Now the problem is that the execution stops at the Set statement with the error:
Invalid procedure call or argument
What is the problem with the statements and how can you rewrite the code to change the interior color of any cell in the column if a value is entered or present in the cell?
Thanks!
If you wish to test for cells that are blank, use a formula of ="". To put that formula in as the Formula1 parameter, you would use Formula1:="="""""
Note: This won't strictly test for any value being entered by the user, because the user could enter a single ' into a cell, or they could insert a formula of ="" into a cell, and both those cells will not be coloured using your conditional format. That probably isn't likely to be an issue but, if it is, a Formula1 of "=AND(A5="""",A5=0)" (i.e. testing that the cell is both a blank string and a number zero - which should only be True if the cell is empty) might work. (Untested)
I want to get content of a cell in Excel whose value is calculated using a Formula (=D6*0.1236) and i am using HssfWorkbook and using getCell() method to get content. But i am getting D6*0.1236. I want to get the value calculated using this formula and not the formula. Please suggest some solution for this.
Below is the code to get the contents
HSSFSheet sheet = workbook.getSheetAt(1);
Row r = sheet.getRow(13);
//get the cell [a particular cell of the row obtained above]
Cell c = r.getCell(2);
You are not suppose to use getCell() to fetch a value. Try the following ,
Cell c = r.getCell(2);
System.out.println("The Cell value is " + c.getNumericCellValue());
In an excel cell, I've placed a simple formula
=C4
The cell typically displays the value of cell C4, but instead I want to see the linked cell ID instead, which in this case is "C4".
Is there a formula to show me this? like:
=SHOWCELL(C4)
The reason I need this instead of simply typing the value of "C4" into the cell, is so Excel will maintain the link to the correct cell even if rows are inserted/deleted, AND show me which cell is linked.
You should be able to use the Cell function.
In Excel, the Cell function can be used to retrieve information about a cell. This can include contents, formatting, size, etc.
=Cell("address", C4)
This displays $C$4.
When inserting a row before C4, it is changed to $C$5.
In case you do not want the $ signs, one way would be the Substitute function:
=Substitute( Cell("address", C4), "$", "" )
You can create your own User Defined Function to achieve this. I call it "CellReference".
Usage:
=CellReference(B6)
displays "B6"
To use it, launch VBA, insert a module, and then copy the below into the module:
Function CellReference(cell As range) As String
CellReference = cell.Address(0, 0, xlA1)
End Function
