Export / Import list formatting

Summary

SharePoint Online provides user interface for defining column and view formatting and forms configuration:

• Use view formatting to customize SharePoint,
• Show or hide columns in a list or library form and
• Configure the list form.

However, the Get-PnPSiteTemplate -Handlers Lists command does not include these customizations. These scripts bridge this gap. The Get-ListFormatting script exports:

• form customizers
• list views
• list views formatting
• columns formatting

to a set of json, csv and xml files. The Set-SPOListFormatting applies the exported customizations to an existing list.

Use it with Get-PnPSiteTemplate and Invoke-PnPSiteTemplate for a full export / import capabilities.

• PnP PowerShell
