Function Compare-WorkSheet {

|

.Synopsis
|
||||
Compares two worksheets with the same name in different files.
|
||||
.Description
|
||||
This command takes two file names, a worksheet name and a name for a key column.
|
||||
It reads the worksheet from each file and decides the column names.
|
||||
It builds as hashtable of the key column values and the rows they appear in
|
||||
It then uses PowerShell's compare object command to compare the sheets (explicity checking all column names which have not been excluded)
|
||||
For the difference rows it adds the row number for the key of that row - we have to add the key after doing the comparison,
|
||||
otherwise rows will be considered as different simply because they have different row numbers
|
||||
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 'Server56.xlsx' -Differencefile 'Server57.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 to register a differnce if if the software was installed on a
|
||||
different date or from a different place, so Excluding Install* removes InstallDate and InstallSource.
|
||||
This data doesn't have a "name" column" so we specify the "IdentifyingNumber" column as the key.
|
||||
The results will be presented as a table.
|
||||
.Example
|
||||
compare-WorkSheet "Server54.xlsx" "Server55.xlsx" -WorkSheetName services -GridView
|
||||
This time two workbooks contain the result of redirecting Get-WmiObject -Class win32_service to Export-Excel
|
||||
Here the -Differencefile and -Referencefile parameter switches are assumed , and the default setting for -key ("Name") works for services
|
||||
This will display the differences between the "services" sheets using a grid view
|
||||
.Example
|
||||
Compare-WorkSheet 'Server54.xlsx' 'Server55.xlsx' -WorkSheetName Services -BackgroundColor lightGreen
|
||||
This version of the command outputs the differences between the "services" pages and also highlights any different rows in the spreadsheet files.
|
||||
.Example
|
||||
Compare-WorkSheet 'Server54.xlsx' 'Server55.xlsx' -WorkSheetName Services -BackgroundColor lightGreen -FontColor Red -Show
|
||||
This builds on the previous example: this time Where two changed rows have the value in the "name" column (the default value for -key),
|
||||
this version adds highlighting of the changed cells in red; and then opens the Excel file.
|
||||
.Example
|
||||
Compare-WorkSheet 'Pester-tests.xlsx' 'Pester-tests.xlsx' -WorkSheetName 'Server1','Server2' -Property "full Description","Executed","Result" -Key "full Description"
|
||||
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 the command specifies a limited set of columns should be used.
|
||||
.Example
|
||||
Compare-WorkSheet 'Server54.xlsx' 'Server55.xlsx' -WorkSheetName general -Startrow 2 -Headername Label,value -Key Label -GridView -ExcludeDifferent
|
||||
The "General" page has a title and two unlabelled columns with a row forCPU, Memory, Domain, Disk and so on
|
||||
So the command is instructed to starts at row 2 to skip the title and to name the columns: the first is "label" and the Second "Value";
|
||||
the label acts as the key. This time we interested the rows which are the same in both sheets,
|
||||
and the result is displayed using grid view. Note that grid view works best when the number of columns is small.
|
||||
.Example
|
||||
Compare-WorkSheet 'Server1.xlsx' 'Server2.xlsx' -WorkSheetName general -Startrow 2 -Headername Label,value -Key Label -BackgroundColor White -Show -AllDataBackgroundColor LightGray
|
||||
This version of the previous command lightlights all the cells in lightgray and then sets the changed rows back to white; only
|
||||
the unchanged rows are highlighted

.Synopsis
|
||||
Compares two worksheets with the same name in different files.
|
||||
.Description
|
||||
This command takes two file names, a worksheet name and a name for a key column.
|
||||
It reads the worksheet from each file and decides the column names.
|
||||
It builds as hashtable of the key column values and the rows they appear in
|
||||
It then uses PowerShell's compare object command to compare the sheets (explicity checking all column names which have not been excluded)
|
||||
For the difference rows it adds the row number for the key of that row - we have to add the key after doing the comparison,
|
||||
otherwise rows will be considered as different simply because they have different row numbers
|
||||
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 'Server56.xlsx' -Differencefile 'Server57.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 to register a differnce if if the software was installed on a
|
||||
different date or from a different place, so Excluding Install* removes InstallDate and InstallSource.
|
||||
This data doesn't have a "name" column" so we specify the "IdentifyingNumber" column as the key.
|
||||
The results will be presented as a table.
|
||||
.Example
|
||||
compare-WorkSheet "Server54.xlsx" "Server55.xlsx" -WorkSheetName services -GridView
|
||||
This time two workbooks contain the result of redirecting Get-WmiObject -Class win32_service to Export-Excel
|
||||
Here the -Differencefile and -Referencefile parameter switches are assumed , and the default setting for -key ("Name") works for services
|
||||
This will display the differences between the "services" sheets using a grid view
|
||||
.Example
|
||||
Compare-WorkSheet 'Server54.xlsx' 'Server55.xlsx' -WorkSheetName Services -BackgroundColor lightGreen
|
||||
This version of the command outputs the differences between the "services" pages and also highlights any different rows in the spreadsheet files.
|
||||
.Example
|
||||
Compare-WorkSheet 'Server54.xlsx' 'Server55.xlsx' -WorkSheetName Services -BackgroundColor lightGreen -FontColor Red -Show
|
||||
This builds on the previous example: this time Where two changed rows have the value in the "name" column (the default value for -key),
|
||||
this version adds highlighting of the changed cells in red; and then opens the Excel file.
|
||||
.Example
|
||||
Compare-WorkSheet 'Pester-tests.xlsx' 'Pester-tests.xlsx' -WorkSheetName 'Server1','Server2' -Property "full Description","Executed","Result" -Key "full Description"
|
||||
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 the command specifies a limited set of columns should be used.
|
||||
.Example
|
||||
Compare-WorkSheet 'Server54.xlsx' 'Server55.xlsx' -WorkSheetName general -Startrow 2 -Headername Label,value -Key Label -GridView -ExcludeDifferent
|
||||
The "General" page has a title and two unlabelled columns with a row forCPU, Memory, Domain, Disk and so on
|
||||
So the command is instructed to starts at row 2 to skip the title and to name the columns: the first is "label" and the Second "Value";
|
||||
the label acts as the key. This time we interested the rows which are the same in both sheets,
|
||||
and the result is displayed using grid view. Note that grid view works best when the number of columns is small.
|
||||
.Example
|
||||
Compare-WorkSheet 'Server1.xlsx' 'Server2.xlsx' -WorkSheetName general -Startrow 2 -Headername Label,value -Key Label -BackgroundColor White -Show -AllDataBackgroundColor LightGray
|
||||
This version of the previous command lightlights all the cells in lightgray and then sets the changed rows back to white; only
|
||||
the unchanged rows are highlighted
