-The Sync-CISExcelAndCsvData function merges data from a specified Excel file with data from either a CSV file or an output object from Invoke-M365SecurityAudit based on a common key. It can also update the Excel worksheet with the merged data. This function is particularly useful for updating Excel records with additional data from a CSV file or audit results while preserving the original formatting and structure of the Excel worksheet.
-.PARAMETER ExcelPath
-The path to the Excel file that contains the original data. This parameter is mandatory.
-.PARAMETER WorksheetName
-The name of the worksheet within the Excel file that contains the data to be synchronized. This parameter is mandatory.
-.PARAMETER CsvPath
-The path to the CSV file containing data to be merged with the Excel data. This parameter is mandatory when using the CsvInput parameter set.
-.PARAMETER AuditResults
-An array of CISAuditResult objects from Invoke-M365SecurityAudit to be merged with the Excel data. This parameter is mandatory when using the ObjectInput parameter set. It can also accept pipeline input.
-.PARAMETER SkipUpdate
-If specified, the function will return the merged data object without updating the Excel worksheet. This is useful for previewing the merged data.
-.EXAMPLE
-PS> Sync-CISExcelAndCsvData -ExcelPath "path\to\excel.xlsx" -WorksheetName "DataSheet" -CsvPath "path\to\data.csv"
-Merges data from 'data.csv' into 'excel.xlsx' on the 'DataSheet' worksheet and updates the worksheet with the merged data.
-.EXAMPLE
-PS> $mergedData = Sync-CISExcelAndCsvData -ExcelPath "path\to\excel.xlsx" -WorksheetName "DataSheet" -CsvPath "path\to\data.csv" -SkipUpdate
-Retrieves the merged data object for preview without updating the Excel worksheet.
-.EXAMPLE
-PS> $auditResults = Invoke-M365SecurityAudit -TenantAdminUrl "https://tenant-admin.url" -DomainName "example.com"
-PS> Sync-CISExcelAndCsvData -ExcelPath "path\to\excel.xlsx" -WorksheetName "DataSheet" -AuditResults $auditResults
-Merges data from the audit results into 'excel.xlsx' on the 'DataSheet' worksheet and updates the worksheet with the merged data.
-.EXAMPLE
-PS> $auditResults = Invoke-M365SecurityAudit -TenantAdminUrl "https://tenant-admin.url" -DomainName "example.com"
-PS> $mergedData = Sync-CISExcelAndCsvData -ExcelPath "path\to\excel.xlsx" -WorksheetName "DataSheet" -AuditResults $auditResults -SkipUpdate
-Retrieves the merged data object for preview without updating the Excel worksheet.
-.EXAMPLE
-PS> Invoke-M365SecurityAudit -TenantAdminUrl "https://tenant-admin.url" -DomainName "example.com" | Sync-CISExcelAndCsvData -ExcelPath "path\to\excel.xlsx" -WorksheetName "DataSheet"
-Pipes the audit results into Sync-CISExcelAndCsvData to merge data into 'excel.xlsx' on the 'DataSheet' worksheet and updates the worksheet with the merged data.
-.INPUTS
-System.String, CISAuditResult[]
-You can pipe CISAuditResult objects to Sync-CISExcelAndCsvData.
-.OUTPUTS
-Object[]
-If the SkipUpdate switch is used, the function returns an array of custom objects representing the merged data.
-.NOTES
-- Ensure that the 'ImportExcel' module is installed and up to date.
-- It is recommended to backup the Excel file before running this script to prevent accidental data loss.
-- This function is part of the CIS Excel and CSV Data Management Toolkit.

+    .SYNOPSIS
+    Synchronizes and updates data in an Excel worksheet with new information from a CSV file, including audit dates.
+    .DESCRIPTION
+    The Sync-CISExcelAndCsvData function merges and updates data in a specified Excel worksheet from a CSV file. This includes adding or updating fields for connection status, details, failure reasons, and the date of the update. It's designed to ensure that the Excel document maintains a running log of changes over time, ideal for tracking remediation status and audit history.
+    .PARAMETER ExcelPath
+    Specifies the path to the Excel file to be updated. This parameter is mandatory.
+    .PARAMETER CsvPath
+    Specifies the path to the CSV file containing new data. This parameter is mandatory.
+    .PARAMETER SheetName
+    Specifies the name of the worksheet in the Excel file where data will be merged and updated. This parameter is mandatory.
+    .EXAMPLE
+    PS> Sync-CISExcelAndCsvData -ExcelPath "path\to\excel.xlsx" -CsvPath "path\to\data.csv" -SheetName "AuditData"
+    Updates the 'AuditData' worksheet in 'excel.xlsx' with data from 'data.csv', adding new information and the date of the update.
+    .INPUTS
+    System.String
+    The function accepts strings for file paths and worksheet names.
+    .OUTPUTS
+    None
+    The function directly updates the Excel file and does not output any objects.
+    .NOTES
+    - Ensure that the 'ImportExcel' module is installed and up to date to handle Excel file manipulations.
+    - It is recommended to back up the Excel file before running this function to avoid accidental data loss.
+    - The CSV file should have columns that match expected headers like 'Connection', 'Details', 'FailureReason', and 'Status' for correct data mapping.
