## DESCRIPTION
The Compare-Worksheet command takes two Worksheets and marks differences in the source document, and optionally outputs a grid showing the changes.
By contrast the Merge-Worksheet command takes the Worksheets and combines them into a single sheet showing the old and new data side by side. Although it is designed to work with Excel data it can work with arrays of any kind of object; so it can be a merge _of_ Worksheets, or a merge _to_ a Worksheet.
## EXAMPLES
### EXAMPLE 1
```text
PS\> Merge-Worksheet "Server54.xlsx" "Server55.xlsx" -WorksheetName services -OutputFile Services.xlsx -OutputSheetName 54-55 -show
```
The workbooks contain audit information for two servers, one sheet contains a list of services.
This command creates a worksheet named "54-55" in a workbook named "services.xlsx" which shows all the services and their differences, and opens the new workbook in Excel.
### EXAMPLE 2
```text
PS\> Merge-Worksheet "Server54.xlsx" "Server55.xlsx" -WorksheetName services -OutputFile Services.xlsx -OutputSheetName 54-55 -HideEqual -AddBackgroundColor LightBlue -show
```
This modifies the previous command to hide the equal rows in the output sheet and changes the color used to mark rows added to the second file.
### EXAMPLE 3
```text
PS\> Merge-Worksheet -OutputFile .\j1.xlsx -OutputSheetName test11 -ReferenceObject (dir .\ImportExcel\4.0.7) -DifferenceObject (dir .\ImportExcel\4.0.8) -Property Length -Show
```
This version compares two directories, and marks what has changed. Because no "Key" property is given, "Name" is assumed to be the key and the only other property examined is length. Files which are added or deleted or have changed size will be highlighed in the output sheet. Changes to dates or other attributes will be ignored.
### EXAMPLE 4
```text
PS\> Merge-Worksheet -RefO (dir .\ImportExcel\4.0.7) -DiffO (dir .\ImportExcel\4.0.8) -Pr Length | Out-GridView
```
This time no file is written and the results - which include all properties, not just length, are output and sent to Out-Gridview.
This version uses aliases to shorten the parameters, \(OutputFileName can be "outFile" and the Sheet can be"OutSheet"; DifferenceObject & ReferenceObject can be DiffObject & RefObject respectively\).
## PARAMETERS
### -Referencefile
First Excel file to compare. You can compare two Excel files or two other objects or a reference obhct against a difference file, but not a reference file against an object. works with the following parameter sets
