Win32::OLE Excel Conditional Formatting error

slick.user has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I'm trying to use Conditional Formatting. I recorded the Macro (comment inside code) and tried to translate to Perl OLE with the code below but got error: Can't call method "Font" on an undefined value at excel_test.pl line 56. I can loop through each cell and check if it not equal to "TRUE" and assign color. I'm trying to avoid looping in Perl.

use strict;
use warnings;
use Win32::OLE;
use Win32::OLE qw(in with);


my $EXCEL = Win32::OLE->new("Excel.Application","Quit");
$EXCEL->{"Visible"} = 1;
$EXCEL->{DisplayAlerts}= 0;

my $outfile = "C:\\test\\file1.xls";
$EXCEL -> {"SheetsInNewWorkBook"} = 1;
my $Workbook = $EXCEL -> Workbooks -> Add();
my $CurrentSheet = $Workbook -> Worksheets(1);


$CurrentSheet->Range("A1")->{"Value"} = "DataA";
$CurrentSheet->Range("A2")->{"Value"} = "abs";
$CurrentSheet->Range("A3")->{"Value"} = "FALSE";
$CurrentSheet->Range("A4")->{"Value"} = "TRUE";
$CurrentSheet->Range("A5")->{"Value"} = "ABC";
$CurrentSheet->Range("A6")->{"Value"} = "xyz";
$CurrentSheet->Range("A7")->{"Value"} = "123";
$CurrentSheet->Range("A8")->{"Value"} = "-99999";
$CurrentSheet->Range("A9")->{"Value"} = "TRUE";
$CurrentSheet->Range("A10")->{"Value"} = "10";

$CurrentSheet->Range("B1")->{"Value"} = "DataB";
$CurrentSheet->Range("B2")->{"Value"} = "absx";
$CurrentSheet->Range("B3")->{"Value"} = "FALSE";
$CurrentSheet->Range("B4")->{"Value"} = "TRUE";
$CurrentSheet->Range("B5")->{"Value"} = "ABCx";
$CurrentSheet->Range("B6")->{"Value"} = "xyzx";
$CurrentSheet->Range("B7")->{"Value"} = "123x";
$CurrentSheet->Range("B8")->{"Value"} = "-99999x";
$CurrentSheet->Range("B9")->{"Value"} = "TRUE";
$CurrentSheet->Range("B10")->{"Value"} = "10x";

$CurrentSheet->Range("C1")->{"Value"} = "A=B?";

#my $rangeFormat = $CurrentSheet->Range("A4");
#$rangeFormat->Interior->{Color} = 255;

#    Columns("A:A").Select
#    Selection.FormatConditions.Add Type:=xlCellValue, Operator:=xlNot
+Equal, _
#        Formula1:="=TRUE"
#    Selection.FormatConditions(Selection.FormatConditions.Count).SetF
+irstPriority
#    With Selection.FormatConditions(1).Font
#        .Color = -16776961
#        .TintAndShade = 0
#    End With
#    Selection.FormatConditions(1).StopIfTrue = True

my $rangeFormat = $CurrentSheet->Range("A:A");
$rangeFormat->FormatConditions->Add({Type=>"xlCellValue", Operator=>"x
+lNotEqual", Formula1=>"=TRUE"});
$rangeFormat->FormatConditions(1)->Font->{Color} = -16776961;

$Workbook->SaveAs({FileName => $outfile, FileFormat => -4143});
$Workbook -> Save();
$EXCEL->Quit();
Win32::OLE->FreeUnusedLibraries();

The VBA macro shows `Type:=xlCellValue` ; in your perl code, you instead have `Type => "xlCellValue"`. The string `"xlCellValue"` is not the same as the constant `xlCellValue` To gain access to the xl* family of constants, Win32::OLE::Const allows you to `use Win32::OLE::Const 'Microsoft Excel';` [download] To use those constants in your call, you need to run `$rangeFormat->FormatConditions->Add({Type=>xlCellValue, Operator=>xlNo +tEqual, Formula1=>"=TRUE"})` [download] When I made those two changes to your code, I was able to see conditional formatting in the spreadsheet your code created.

Thanks. I used Danny's solution. Win32::OLE::Const 'Microsoft Excel'; has to be on Win32 Excel only. I'm using Win64 Excel version.	[reply]

That means, for whatever reason, `$rangeFormat->FormatConditions(1)` is not defined at line 56.	[reply] [d/l]

I just installed Win32::OLE and changed line 56 to `$rangeFormat->Font->{Color} = -16776961;` [download] and it made the font in the first column red, if that is what you were trying to do.	[reply] [d/l]

A4 & A9 should not be red because of Conditional Formatting. It is not apply right now. I was trying to follow macro code.	[reply]

It looks like you need to use numeric values for Type and Operator in `FormatConditions->Add`. For example `$rangeFormat->FormatConditions->Add({Type=>1, Operator=>4, Formula1=>" +=TRUE"}); $rangeFormat->FormatConditions(1)->Font->{Color} = -16776961;` [download] makes cells in the first column red except A4 and A9. Here are the codes for Type and Operator.	[reply] [d/l] [select]

I was trying to use Conditional Formatting, if it is not "TRUE" to highlight all red.	[reply]

When I used to use Windows regularly and I saw that you could write stuff with less code I never looked back...(this is just a style comment btw) `#!/usr/bin/perl -w use strict; my @data = qw~DataB absx FALSE TRUE ABCx xzx 123x .99999x TRUE 10x~; for(0..$#data){ my $n= $_+1; print qq~\$CurrentSheet->Range("A$n")->{"Value"} = "$data[$_]"\n~; } 1;` [download] Celebrate Intellectual Diversity	[reply] [d/l]
