I can not find a formulat that multiplies chances the way i want.
I can not use additional cells or VBA because this is a company excel sheet that is locked to a certain format.
Here is some pseudocode that illustrates what i want to do;
value oneminus(value) //typeof delegate
{
return 1 - value;
}
value ProductDelegate(range, delegate)
{
Result result = 1;
foreach value in range
{
result *= delegate(value);
}
return result;
}
What i would want to call is a prefabricated version of the ProductDelegate. I would call it like so =ProductDelegate(J56:J73, "1-"&J). I do not think that ProductDelegate actually exists so i feel like what i am asking is not implemented in excel. Are there any options for this particular usecase? Any statistics function i am missing?
You don't need VBA for this. Just type the following formula but hold down CTRL-SHFT when hitting enter:
=PRODUCT(1-J56:J73)

I have a table in Tabulator and would like to show all 0 values in the cells as blank. What's the best way to achieve this?
My first attempt was to write a custom mutator:
mutator: function(value, data, type, params, component){
if (value == 0){
return "";
}
else{
return value;
}
}
This works but feels wrong. Further, I would like to create calculated fields on top of this and this doesn't work properly with the blank strings. Then I need to re-convert them back to zeroes in the next function.
Thanks for your help
you can create a function that returns a copy of the original array but with all 0 values in the cells as blank then you display it, and each time you need to calculate or update you do it based on/in the original one then you always display the copy
Just use a cell formatter. A mutator will change the data but I don't think you want this - you just want to change the display of the data.
See my Codepen here and take a look at the moneyColFormatter function.
Specifically, in the cell definition:
...
formatter: (cell) => this.moneyColFormatter(cell),
and then implement it somehow
private moneyColFormatter(cell): string {
// If we want to show 0 values as blank:
if (!cell.getValue()) {
return "";
}
return cell.getValue();
}
The Codepen also contains aggregated functions, calculated cols and custom dynamic columns.
I am writing some if conditions in excel and i don`t succeed. I would glad if you can help me.
I want to write the following if condition(Pseudo code):
If(L28 appears between C44:C47)
{
Value = D31
}
else if( L28 ==C48)
{
Value = D32
}
If(L28 appears between C49:C53)
{
Value = D30
}
else If(L28 appears between C54:C57)
{
Value = D29
}
else
{
Value = L28
}
I have written the following part of code, but it is does not work.
"=IF(COUNTIF(C44:C47,L28),D31,if(L28=C48,D32,if(COUNTIF(C49:C53,L28),D30,if(COUNTIF(C54:C57,L28),D29))))"
Well, try this, but I have not tested it:
=if(iferror(match(L28,C44:C47,0),0)>0,D31,if(L28=C48,D32,if(iferror(match(L28,CC49:C53,0),0)>0,D30,if(iferror(match(L28,C54:C57,0),0)>0,D29,L28))))
Excel has a new ifs() function in one of the latest updates.
ifs(condition1, value1, condition2, value2,...) outputs the value for the first condition that is true.
that could simplify the formula a bit. No more need for nested if(). Below is Solar Mikes solution with ifs().
=ifs(iferror(match(L28,C44:C47,0),0)>0,D31,L28=C48,D32,iferror(match(L28,CC49:C53,0),0)>0,D30,iferror(match(L28,C54:C57,0),0>0,D29,L28)
I am using the EPPlus library in my ASP.Net application.
What I am trying to do is open a spreadsheet, input some values into cells and then read another cell which contains the result of a calculation. The spreadsheet itself is confidential so I can't provide many details on it.
In order to get my calculations to work I have had to modify the source code for EPplus, changing the Compile function in the ExcelAddressExpression.cs file to ignore the ParentIsLookupFunction bool as shown at the bottom of the question.
so it was able to evaluate the term 5*$f$7
What I want to know is what situations is it useful to keep the CompileResult as an ExcelAddress, so I do not run into any incorrect calculations or errors in other parts of the spreadsheet.
For reference here are the steps I went though to get here:
My code is something like this
using (ExcelPackage p = new ExcelPackage(FilePath, true))
{
ExcelWorksheet ws = p.Workbook.Worksheets["Calculations"];
ws.Cells["b7"].Value = 50;
ws.Cells["f9"].Value = 500000;
ws.Cells["j216"].Calculate();
string result = ws.Cells["j216"].Value.ToString();
}
The formula in cell J216 is
=VLOOKUP($B$7+$F$221+$K$13-$F$8-1,Sheet2!$A$4:$T$103,5*$F$7+2*$B$8+$B$9-5,FALSE)
and the result I got was '#VALUE!'
I have attached a log file and found the issue is in the VLookup function
Worksheet: Calculations
Address: J216
OfficeOpenXml.FormulaParsing.Exceptions.ExcelErrorValueException: #VALUE!
at OfficeOpenXml.FormulaParsing.Excel.Functions.IntArgumentParser.Parse(Object obj)
at OfficeOpenXml.FormulaParsing.Excel.Functions.RefAndLookup.LookupArguments..ctor(IEnumerable`1 arguments, ArgumentParsers argumentParsers, ParsingContext context)
at OfficeOpenXml.FormulaParsing.Excel.Functions.RefAndLookup.VLookup.Execute(IEnumerable`1 arguments, ParsingContext context)
at OfficeOpenXml.FormulaParsing.ExpressionGraph.FunctionCompilers.LookupFunctionCompiler.Compile(IEnumerable`1 children, ParsingContext context)
at OfficeOpenXml.FormulaParsing.ExpressionGraph.FunctionExpression.Compile()
The next step I took was to download the source code for EPPlus, and debug through the code as it executed, eventually finding the problem was at line 165 of Operator.cs
l = l ?? new CompileResult(0, DataType.Integer);
r = r ?? new CompileResult(0, DataType.Integer);
if (l.DataType == DataType.Integer && r.DataType == DataType.Integer)
{
return new CompileResult(l.ResultNumeric*r.ResultNumeric, DataType.Integer);
}
else if ((l.IsNumeric || l.IsNumericString || l.IsDateString || l.Result is ExcelDataProvider.IRangeInfo) &&
(r.IsNumeric || r.IsNumericString || r.IsDateString || r.Result is ExcelDataProvider.IRangeInfo))
{
return new CompileResult(l.ResultNumeric*r.ResultNumeric, DataType.Decimal);
}
return new CompileResult(eErrorType.Value);
When evaluating the equation 5*$F$7, the second parameter was of DataType ExcelAddress which is results in a compile result exception being thrown.
The root cause of this is in the Compile function of the ExcelAddressExpression.cs file the ParentIsLookupFunction boolean controls whether the cell is evaluated or left as an address.
public override CompileResult Compile()
{
if (ParentIsLookupFunction)
{
return new CompileResult(ExpressionString, DataType.ExcelAddress);
}
else
{
return CompileRangeValues();
}
}
I have modified my version of the code to simply be
public override CompileResult Compile()
{
return CompileRangeValues();
}
As said at the top of the question, what I want to know is why would you want to return the ExcelAddress CompileResult, It was obviously put there for a reason and I do not want to break some other calculations in my spreadsheet.
I can confirm though that for at least this calculation it is now working correctly.
I wrote the formula engine of EPPlus some years ago, but don't work much on the project these days. If I recall it correctly there are cases where you don't want to compile the excel address in the expression, but rather pass it on to the executing function. Have you tried to run the unit tests? The formula engine is covered by hundreds of tests and the test result could provide some guidance.
I was able to answer this after experimenting with different spreadsheets.
Returning the value as an ExcelAddress is useful in the event that the address is not operated on like in my earlier example 5*$F$7 such as an IF statement inside a VLookup.
In the event that there is an operator you will want to return the contents of the cell.
I modified the EPPlus code to now check for any operators separating terms in the formula
public override CompileResult Compile()
{
if (ParentIsLookupFunction &&
Operator == null &&
(Prev == null || Prev.Operator == null))
{
return new CompileResult(ExpressionString, DataType.ExcelAddress);
}
else
{
return CompileRangeValues();
}
}
I have a simplified test scenario created where I have a spreadsheet with two cells (C2/C3) having an array formula:
{=NaNTest()}
My simplified CustomFunction is as follows:
public class NaNTest : CustomFunctions.Function
{
public NaNTest() : this( "NaNTest" ) { }
public NaNTest( string name ) : base( name, CustomFunctions.Volatility.Invariant, CustomFunctions.ValueType.Variant ) { }
public override void Evaluate( CustomFunctions.IArguments a, CustomFunctions.IValue r )
{
var result = new double[ 1, 2 ];
result[ 0, 0 ] = double.NaN;
result[ 0, 1 ] = 0d;
r.SetArray( result );
}
}
This sets both C2 and C3 to #NUM! when I'd expect only C2 to be. Is there a way to make it correctly* assign C3 to 0?
Thanks in advance.
* I say correctly because we have to implement an Excel add-in that our clients use to author spreadsheets and it provides same 'functionality' that we provide on 'our servers' when we open/process the spreadsheet in our 'SpreadsheetGear calculations' (i.e. the NaNTest() function above). The libraries we use to create the add-in only assign C2 to #NUM! and having the two implementations (client side add-in vs server side SpreadsheetGear) behaving differently makes maintenance/debugging difficult.
This behavior is by design. Note the comment in the documentation for the IValue.SetArray(...) method:
If any of the numbers in the array are not valid numbers, the result
of the custom function will be ValueError.Num.
Since NaN isn't a valid number the entire array will resolve to #NUM! instead. Actually, if you try to set a cell value on its out (outside of a custom function), such as...
worksheet.Cells["A1"].Value = double.NaN;
...you should find that cell evaluates to #NUM! as well. If such cases can occur in your custom function, you'll likely just need to write a check for this condition and respond in whatever manner is required by your application.
I'm having issues using YUI's DataTable Column Selection Functionality. I've tried,
myEndColDataTable.subscribe("theadCellClickEvent", myEndColDataTable.onEventSelectColumn);
and
myEndColDataTable.subscribe("cellClickEvent", function (oArgs) {
this.selectColumn(this.getColumn(oArgs.target));
});
The issue is, I have an initial column selected programmatically. I can highlight the other column, but it doesn't remove the selection from the initially-selected column.
You are correct - there is no quick clean solution.
YUI DataTable currently (as of 2.8) lacks an unselectAllColmns method to match unselectAllRows (which is called by onEventSelectRow).
It is also worth noting that onEventSelectColumn selects the column header, so unselectAllCells will not work.
You could implement your own unselectAllColumns() function like this:
function unselectAllColumns (dataTable) {
var i, oColumn, oColumnSet = dataTable.getColumnSet();
for (i=0; i<oColumnSet.keys.length; i++) {
oColumn = oColumnSet.keys[i];
if (oColumn.selected) {
dataTable.unselectColumn(oColumn);
}
}
}
This will be marginally more efficient than using getSelectedColumns() because you will not need to build an intermediate array of only selected columns (looking at the source getSelectedColumns calls getColumnSet and walks the array just as above).
I guess I can do this, but its not elegant. There has to be a better way.
myEndColDataTable.subscribe("cellClickEvent", function (oArgs) {
var colUnSelect = myEndColDataTable.getSelectedColumns();
myEndColDataTable.unselectColumn(colUnSelect[0]);
myEndColDataTable.selectColumn(myEndColDataTable.getColumn(oArgs.target));
});
