List of Perl commands to manipulate Windows Excel with Win32::OLE module [closed]

Answer 1

This is the list of operations I have gathered while writing my scripts on Excel with Win32 module. I would like to share.

Feel free to comment/edit in order to improve.

1. Opening and Saving Excel/Workbooks

#Modules to use
use Cwd 'abs_path';
use Win32::OLE;
use Win32::OLE qw(in with);
use Win32::OLE::Const "Microsoft Excel";
$Win32::OLE::Warn = 3;

#Need to use absolute path for Excel files
my $excel_file = abs_path("$Excel_path") or die "Error: the file $Excel_path has not been found\n";

# Open Excel application
my $Excel = Win32::OLE->GetActiveObject('Excel.Application')
    || Win32::OLE->new('Excel.Application', 'Quit');

# Open Excel file
my $Book = $Excel->Workbooks->Open($excel_file);

#Make Excel visible
$Excel->{Visible} = 1;

#___ ADD NEW WORKBOOK
my $Book = $Excel->Workbooks->Add;
my $Sheet = $Book->Worksheets("Sheet1");
$Sheet->Activate;

#Save Excel file
$Excel->{DisplayAlerts}=0; # This turns off the "This file already exists" message.
$Book->Save; #Or $Book->SaveAs("C:\\file_name.xls");
$Book->Close; #or $Excel->Quit;

2. Manipulation of Worksheets

#Get the active Worksheet 
my $Book = $Excel->Activewindow;
my $Sheet = $Book->Activesheet;

#List of Worksheet names
my @list_Sheet = map { $_->{'Name'} } (in $Book->{Worksheets});

#Access a given Worksheet
my $Sheet = $Book->Worksheets($list_Sheet[0]);

#Add new Worksheet
$Book->Worksheets->Add({After => $workbook->Worksheets($workbook->Worksheets->{Count})});

#Change Worksheet Name
$Sheet->{Name} = "Name of Worksheet";

#Freeze Pane
$Excel -> ActiveWindow -> {FreezePanes} = "True";

#Delete Sheet
$Sheet -> Delete;

3. Manipulation of cells

#Edit the value of a cell (2 methods)
$Sheet->Range("A1")->{Value} = 1234;
$Sheet->Cells(1,1)->{Value} = 1234;

#Edit the values in a range of cells
$Sheet->Range("A8:C9")->{Value} = [[ undef, 'Xyzzy', 'Plugh' ],
                               [ 42,    'Perl',  3.1415  ]];

#Edit the formula in a cell (2 types)
$Sheet->Range("A1")->{Formula} = "=A1*9.81";
$Sheet->Range("A3")->{FormulaR1C1} = "=SUM(R[-2]C:R[-1]C)";      # Sum of rows
$Sheet->Range("C1")->{FormulaR1C1} = "=SUM(RC[-2]:RC[-1])";      # Sum of columns

#Edit the format of the text (font)
$Sheet->Range("G7:H7")->Font->{Bold}       = "True";
$Sheet->Range("G7:H7")->Font->{Italic}     = "True";
$Sheet->Range("G7:H7")->Font->{Underline}  = xlUnderlineStyleSingle;
$Sheet->Range("G7:H7")->Font->{Size}       = 8;
$Sheet->Range("G7:H7")->Font->{Name}       = "Arial";
$Sheet->Range("G7:H7")->Font->{ColorIndex} = 4;

#Edit the number format
$Sheet -> Range("G7:H7") -> {NumberFormat} = "\@";                              # Text
$Sheet -> Range("A1:H7") -> {NumberFormat} = "\$#,##0.00";                       # Currency
$Sheet -> Range("G7:H7") -> {NumberFormat} = "\$#,##0.00_);[Red](\$#,##0.00)";  # Currency - red negatives
$Sheet -> Range("G7:H7") -> {NumberFormat} = "0.00_);[Red](0.00)";               # Numbers with decimals
$Sheet -> Range("G7:H7") -> {NumberFormat} = "#,##0";                          #     Numbers with commas
$Sheet -> Range("G7:H7") -> {NumberFormat} = "#,##0_);[Red](#,##0)";            # Numbers with commas - red negatives
$Sheet -> Range("G7:H7") -> {NumberFormat} = "0.00%";                           # Percents
$Sheet -> Range("G7:H7") -> {NumberFormat} = "m/d/yyyy"                         # Dates

#Align text
$Sheet -> Range("G7:H7") -> {HorizontalAlignment} = xlHAlignCenter;              # Center text;
$Sheet -> Range("A1:A2") -> {Orientation} = 90;                                 # Rotate text

#Activate Cell
$Sheet -> Range("A2") -> Activate;

$Sheet->Hyperlinks->Add({   
   Anchor          =>  $range, #Range of cells with the hyperlink; e.g. $Sheet->Range("A1")
   Address         =>  $adr, #File path, http address, etc.
   TextToDisplay   =>  $txt, #Text in the cell
   ScreenTip       =>  $tip, #Tip while hovering the mouse over the hyperlink
});

N.B: to retrieve the list of hyperlinks, have a look at the following post Getting list of hyperlinks from an Excel worksheet with Perl Win32::OLE

4. Manipulation of Rows / Columns

#Insert a row before/after line 22
$Sheet->Rows("22:22")->Insert(xlUp, xlFormatFromRightOrBelow);
$Sheet->Rows("23:23")->Insert(-4121,0);  #xlDown is -4121 and that xlFormatFromLeftOrAbove is 0

#Delete a row
$Sheet->Rows("22:22")->Delete();

#Set column width and row height
$Sheet -> Range('A:A') -> {ColumnWidth} = 9.14;
$Sheet -> Range("8:8") -> {RowHeight}   = 30;
$Sheet -> Range("G:H") -> {Columns} -> Autofit;

# Get the last row/column
my $last_row = $Sheet -> UsedRange -> Find({What => "*", SearchDirection => xlPrevious, SearchOrder => xlByRows})    -> {Row};
my $last_col = $Sheet -> UsedRange -> Find({What => "*", SearchDirection => xlPrevious, SearchOrder => xlByColumns}) -> {Column};


#Add borders (method 1)
$Sheet -> Range("A3:H3") -> Borders(xlEdgeBottom)       -> {LineStyle}  = xlDouble;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeBottom)       -> {Weight}     = xlThick;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeBottom)       -> {ColorIndex} = 1;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeLeft)         -> {LineStyle}  = xlContinuous;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeLeft)         -> {Weight}     = xlThin;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeTop)          -> {LineStyle}  = xlContinuous;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeTop)          -> {Weight}     = xlThin;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeBottom)       -> {LineStyle}  = xlContinuous;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeBottom)       -> {Weight}     = xlThin;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeRight)        -> {LineStyle}  = xlContinuous;
$Sheet -> Range("A3:H3") -> Borders(xlEdgeRight)        -> {Weight}     = xlThin;
$Sheet -> Range("A3:H3") -> Borders(xlInsideVertical)   -> {LineStyle}  = xlDashDot
$Sheet -> Range("A3:H3") -> Borders(xlInsideVertical)   -> {Weight}     = xlMedium;
$Sheet -> Range("A3:I3") -> Borders(xlInsideHorizontal) -> {LineStyle}  = xlContinuous;
$Sheet -> Range("A3:I3") -> Borders(xlInsideHorizontal) -> {Weight}     = xlThin;

#Add borders (method 2)
my @edges = qw (xlInsideHorizontal xlInsideVertical xlEdgeBottom xlEdgeTop xlEdgeRight);
foreach my $edge (@edges)
{
    with (my $Borders = $Sheet->Range("A3:H3")->Borders(eval($edge)), 
          LineStyle =>xlContinuous, Weight => xlThin , ColorIndex => 1);
}

#Merge Cells
$Sheet -> Range("H10:J10") -> Merge;

#Group Rows
$Sheet -> Range("7:8") -> Group;

#Hide Columns
$Sheet -> Range("G:H") -> EntireColumn -> {Hidden} = "True";

5. Misc

#Add a name (i.e. reference)
$Book->Names->Add($name =>"=$ref"); #Where $name points to the range $ref

#Insert a picture
$Sheet -> Pictures -> Insert("picture_name");                # Insert in upper-left corner
$Excel -> ActiveSheet -> Pictures -> Insert("picture_name"); # Insert in active cell


#Print setup
$Sheet -> PageSetup -> {Orientation}  = xlLandscape;
$Sheet -> PageSetup -> {Order}        = xlOverThenDown;
$Sheet -> PageSetup -> {LeftMargin}   = .25;
$Sheet -> PageSetup -> {RightMargin}  = .25;

$Sheet -> PageSetup -> {Zoom}         = 75;
$Sheet -> PageSetup -> FitToPagesWide = 1;
$Sheet -> PageSetup -> FitToPagesTall = 1;

#Add a Page break
$Excel -> ActiveWindow -> SelectedSheets -> HPageBreaks -> Add({Before => $Sheet -> Range("3:3")});
