We also add the name of the file in which the difference occurs.
If -BackgroundColor is specified the difference rows will be changed to that background.
.Example
compare-WorkSheet -Referencefile 'Server1.xlsx' -Differencefile 'Server2.xlsx' -WorkSheetName Products -key IdentifyingNumber -ExcludeProperty Install* | format-table
Compare-WorkSheet -Referencefile 'Server1.xlsx' -Differencefile 'Server2.xlsx' -WorkSheetName Products -key IdentifyingNumber -ExcludeProperty Install* | format-table
The two workbooks in this example contain the result of redirecting a subset of properties from Get-WmiObject -Class win32_product to Export-Excel
The command compares the "products" pages in the two workbooks, but we don't want a match if the software was installed on a
different date or from a different place, so Excluding Install* removes InstallDate and InstallSource. The results will be presented as a table.
.Example
compare-WorkSheet 'Server1.xlsx' 'Server2.xlsx' -WorkSheetName Services -key Name -BackgroundColor lightGreen
Compare-WorkSheet 'Server1.xlsx' 'Server2.xlsx' -WorkSheetName Services -key Name -BackgroundColor lightGreen
This time two workbooks contain the result of redirecting Get-WmiObject -Class win32_service to Export-Excel
This command compares the "services" pages and highlights the rows in the spreadsheet files.
Here the -Differencefile and -Referencefile parameter switches are assumed
.Example
compare-WorkSheet 'Server1.xlsx' 'Server2.xlsx' -WorkSheetName Services -BackgroundColor lightGreen -fontColor Red -Show
Compare-WorkSheet 'Server1.xlsx' 'Server2.xlsx' -WorkSheetName Services -BackgroundColor lightGreen -fontColor Red -Show
This builds on the previous example: this time Where two rows in the services have the same name, this will also highlight the changed cells in red.
This example will open the Excel files and omits the -key parameter because "Name" will be assumed to the label for the key column
.Example
compare-WorkSheet 'Pester-tests.xlsx' 'Pester-tests.xlsx' -WorkSheetName 'Server1','Server2' -Property "full Description","Executed","Result" -Key "full Description" -FontColor Red -TabColor Yellow -Show
Compare-WorkSheet 'Pester-tests.xlsx' 'Pester-tests.xlsx' -WorkSheetName 'Server1','Server2' -Property "full Description","Executed","Result" -Key "full Description" -FontColor Red -TabColor Yellow -Show
This time the reference file and the difference file are the same file and two different sheets are used. Because the tests include the
machine name and time the test was run only a limited set of columns.
.Example
Compare-WorkSheet - 'Server1.xlsx' 'Server2.xlsx' -WorkSheetName general -Startrow 2 -Headername Label,value -Key Label -GridView
The "General" page has a title and two unlabelled columns with the CPU, Memory, Domain, Disk and so on
So this version starts at row 2 to skip the tiltle and labels the first column "label" and the Second "Value"; the label acts as the key
and the result is display on using grid view. Note that grid view works best when the number of columns is small.
