Examples

Example 1: Single Site with WhatIf (local)

.\SPSCleanVersions.ps1 -InputJson '{"SiteUrls":["https://contoso.sharepoint.com/sites/News"],"KeepMajorVersions":50}' -WhatIf

Example 2: Local run from a JSON config file

.\SPSCleanVersions.ps1 -ConfigFile '.\Config\contoso-PROD.json'

Example 3: Multiple Sites with DryRun (Azure Automation Runbook)

.\SPSCleanVersions.ps1 -InputJson '{"SiteUrls":["https://contoso.sharepoint.com/sites/News","https://contoso.sharepoint.com/sites/HR"],"KeepMajorVersions":50,"DryRun":true}'

Example 4: Force Deletion of Old File Version History

Set "ForceDeleteOldVersions": true to submit a batch delete job that removes old file versions exceeding the configured limits via New-PnPSiteFileVersionBatchDeleteJob.

Note: Batch delete requires delegated user context. It is automatically skipped when running in Azure Automation (Managed Identity / app-only). A warning is displayed in that case.

.\SPSCleanVersions.ps1 -InputJson '{"SiteUrls":["https://contoso.sharepoint.com/sites/News"],"KeepMajorVersions":50,"ForceDeleteOldVersions":true,"DryRun":true}'

Error Handling

Ensure the provided credentials have access to the SharePoint Sites.
