.SYNOPSIS
|
||
Create custom objects from the rows in an Excel worksheet.
|
||
|
||
.DESCRIPTION
|
||
The Import-Excel cmdlet creates custom objects from the rows in an Excel worksheet. Each row represents one object. All of this is possible without installing Microsoft Excel and by using the .NET library ‘EPPLus.dll’.
|
||
|
||
By default, the property names of the objects are retrieved from the column headers. Because an object cannot have a blank property name, only columns with column headers will be imported.
|
||
|
||
If the default behavior is not desired and you want to import the complete worksheet ‘as is’, the parameter ‘-NoHeader’ can be used. In case you want to provide your own property names, you can use the parameter ‘-HeaderName’.
|
||
|
||
.PARAMETER Path
|
||
Specifies the path to the Excel file.
|
||
.PARAMETER ExcelPackage
|
||
Instead of specifying a path provides an Excel Package object (from Open-ExcelPackage)
|
||
Using this avoids re-reading the whole file when importing multiple parts of it.
|
||
To allow multiple read operations Import-Excel does NOT close the package, and you should use
|
||
Close-ExcelPackage -noSave to close it.
|
||
.PARAMETER WorksheetName
|
||
Specifies the name of the worksheet in the Excel workbook to import. By default, if no name is provided, the first worksheet will be imported.
|
||
|
||
.PARAMETER DataOnly
|
||
Import only rows and columns that contain data, empty rows and empty columns are not imported.
|
||
|
||
.PARAMETER HeaderName
|
||
Specifies custom property names to use, instead of the values defined in the column headers of the TopRow.
|
||
If you provide fewer header names than there are columns of data in the worksheet, then data will only be imported from that number of columns - the others will be ignored.
|
||
If you provide more header names than there are columns of data in the worksheet, it will result in blank properties being added to the objects returned.
|
||
|
||
.PARAMETER NoHeader
|
||
Automatically generate property names (P1, P2, P3, ..) instead of the ones defined in the column headers of the TopRow.
|
||
This switch is best used when you want to import the complete worksheet ‘as is’ and are not concerned with the property names.
|
||
|
||
.PARAMETER StartRow
|
||
The row from where we start to import data, all rows above the StartRow are disregarded. By default this is the first row.
|
||
When the parameters ‘-NoHeader’ and ‘-HeaderName’ are not provided, this row will contain the column headers that will be used as property names. When one of both parameters are provided, the property names are automatically created and this row will be treated as a regular row containing data.
|
||
|
||
.PARAMETER EndRow
|
||
By default all rows up to the last cell in the sheet will be imported. If specified, import stops at this row.
|
||
|
||
.PARAMETER StartColumn
|
||
The number of the first column to read data from (1 by default).
|
||
|
||
.PARAMETER EndColumn
|
||
By default the import reads up to the last populated column, -EndColumn tells the import to stop at an earlier number.
|
||
|
||
.PARAMETER Password
|
||
Accepts a string that will be used to open a password protected Excel file.
|
||
|
||
.EXAMPLE
|
||
Import data from an Excel worksheet. One object is created for each row. The property names of the objects consist of the column names defined in the first row. In case a column doesn’t have a column header (usually in row 1 when ‘-StartRow’ is not used), then the unnamed columns will be skipped and the data in those columns will not be imported.

|
||
|
||
Notice that column 'B' is not imported because there's no value in cell 'B1' that can be used as property name for the objects.
|
||
|
||
.EXAMPLE
|
||
Import the complete Excel worksheet ‘as is’ by using the ‘-NoHeader’ switch. One object is created for each row. The property names of the objects will be automatically generated (P1, P2, P3, ..).

|
||
Import data from an Excel worksheet. One object is created for each row. The property names of the objects consist of the names defined in the parameter ‘-HeaderName’. The properties are named starting from the most left column (A) to the right. In case no value is present in one of the columns, that property will have an empty value.

.EXAMPLE
|

Import data from an Excel worksheet. One object is created for each row. The property names of the objects are automatically generated by using the switch ‘-NoHeader’ (P1, P@, P#, ..). The switch ‘-DataOnly’ will speed up the import because empty rows and empty columns are not imported.

Notice that only 1 object is imported with only 3 properties. Column B and row 2 are empty and have been disregarded by using the switch '-DataOnly'. The property names have been named with the values provided with the parameter '-HeaderName'. Row number 1 with ‘Chuck Norris’ has not been imported, because we started the import from row 2 with the parameter ‘-StartRow 2’.

PS> ,(Import-Excel -Path .\SysTables_AdventureWorks2014.xlsx) |
|
||
Write-SqlTableData -ServerInstance localhost\DEFAULT -Database BlankDB -SchemaName dbo -TableName MyNewTable_fromExcel -Force
|
||
|
||
Imports data from an Excel file and pipe the data to the Write-SqlTableData to be INSERTed into a table in a SQL Server database.
|
||
The ",( ... )" around the Import-Excel command allows all rows to be imported from the Excel file, prior to pipelining to the Write-SqlTableData cmdlet. This helps prevent a RBAR scenario and is important when trying to import thousands of rows.
|
||
The -Force parameter will be ignored if the table already exists. However, if a table is not found that matches the values provided by -SchemaName and -TableName parameters, it will create a new table in SQL Server database. The Write-SqlTableData cmdlet will inherit the column names & datatypes for the new table from the object being piped in.
|
||
NOTE: You need to install the SqlServer module from the PowerShell Gallery in oder to get the Write-SqlTableData cmdlet.
