Set-SPExcelFileLocation [-Identity] <SPExcelFileLocationPipeBind> -ExcelServiceApplication <SPExcelServiceApplicationPipeBind> [-AbortOnRefreshOnOpenFail <SwitchParameter>] [-Address <String>] [-AssignmentCollection <SPAssignmentCollection>] [-AutomaticVolatileFunctionCacheLifetime <Int32>] [-ChartAndImageSizeMax <Int32>] [-ChartRenderDurationMax <Int32>] [-ConcurrentDataRequestsPerSessionMax <Int32>] [-Confirm [<SwitchParameter>]] [-DefaultWorkbookCalcMode <File | Manual | Auto | AutoDataTables>] [-Description <String>] [-DisplayGranularExtDataErrors <SwitchParameter>] [-ExternalDataAllowed <None | Dcl | DclAndEmbedded>] [-IncludeChildren <SwitchParameter>] [-LocationType <SharePoint | Unc | Http>] [-ManualExtDataCacheLifetime <Int32>] [-NewWorkbookSessionTimeout <Int32>] [-PeriodicExtDataCacheLifetime <Int32>] [-RequestDurationMax <Int32>] [-RESTExternalDataAllowed <SwitchParameter>] [-SessionTimeout <Int32>] [-ShortSessionTimeout <Int32>] [-UdfsAllowed <SwitchParameter>] [-WarnOnDataRefresh <SwitchParameter>] [-WhatIf [<SwitchParameter>]] [-WorkbookSizeMax <Int32>]

The Set-SPExcelFileLocation cmdlet sets properties of a location from which Excel Services Application loads workbooks. Excel Services Application loads only workbooks that are stored in a trusted file location. Properties of trusted file locations control how workbooks can be used when they are loaded on Excel Services Application. Excel Services Application always enforces the properties that are defined by the trusted file location from which a workbook was loaded. The properties that are used by the trusted file location are determined by comparison of the file path for the workbook with the Address parameter of the trusted file location.

 

Parameter Required Type Description

Identity

Required

Microsoft.Office.Excel.Server.Cmdlet.SPExcelFileLocationPipeBind

Specifies the FileLocation object to update. The name must be unique in the list of file locations.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid string identifying the file location, in the form http://myPortal/myTeam; a valid string identifying the path, in the form C:\folder_name; or an instance of a valid SPExcelFileLocation object.

ExcelServiceApplication

Required

Microsoft.Office.Excel.Server.Cmdlet.SPExcelServiceApplicationPipeBind

Specifies the Excel Services Application Web service application that contains the SPExcelFileLocation list object.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of an Excel Services Application Web service application in the farm (for example, MyExcelService1); or an instance of a valid SPExcelServiceApplication object.

AbortOnRefreshOnOpenFail

Optional

System.Management.Automation.SwitchParameter

Specifies that the load of a Excel Services Application file automatically fails if an automatic data refresh operation fails when the file is opened. The load is failed only if the following conditions are true:

-- User has read-only permissions to the Excel Services Application file.

-- Workbook file has data connections that refresh automatically when the Excel file is opened.

Address

Optional

System.String

Specifies a Web folder, or file directory from which Excel Services Application can load workbooks.

The type must be a valid URL, in the form http://myPortal/myTeam; or a valid UNC path in form, \\server_name\folder_name

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

noteNote
When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

AutomaticVolatileFunctionCacheLifetime

Optional

System.Int32

Specifies the maximum time, in seconds, that a computed value for a volatile function is cached for automatic recalculations. Valid values include:

-1, calculate once when the workbook loads

0, always calculate

The type must be the integers -1 or 0, or an integer value in the range of 1 to 2073600.

ChartAndImageSizeMax

Optional

System.Int32

Specifies the maximum size, in megabytes, of a chart or image that can be opened. The default value is 1.

--------------EXAMPLE 1--------------

Get-SPExcelFileLocation -ExcelServiceApplication "My Excel Service" | where { $_.externaldataallowed -eq "DclAndEmbedded"} | Set-SPExcelFileLocation -ExernalDataAllowed Dcl

This example gets every trusted file location for the Excel Services Application Web service application named My Excel Service that allows data connections to load from workbook files and specifies that the locations must use a data connection library to load data connections.

--------------EXAMPLE 2--------------

Get-SPExcelServiceApplication | Get-SPExcelFileLocation | where {$_.Address -eq "http://"} | Set-SPExcelFileLocation -Description "This is the default trusted file location for Excel Services Application. It allows any file from anywhere in SharePoint to load."

This example changes the description of the default file location for every Excel Services Application Web service application in the farm.
