Automating GDPR-Compliant File Cleanup with Excel VBA + OneDrive

🧩 The Problem: Forgotten Files, Serious Risk

In GDPR-regulated environments, storing client/user data longer than allowed (commonly 90 days) can trigger compliance violations. But in the real world?

Old CSVs, exported logs, and test files quietly pile up on desktops and downloads folders — unnoticed and unmanaged.

During an internal audit, we realized:

• There was no easy way to track or clean up aged data locally

• Employees were unaware of files lying dormant for 100+ days

• Manual review was not scalable across devices

🔧 The Solution: Automated File Scanner with Cleanup Actions

We built a lightweight Excel + VBA automation that:

1. Scans a selected folder (e.g., C:, D:, Downloads) for files older than 90 days

2. Logs file name, path, days old into an Excel sheet

3. Adds a dropdown for each file with three action options:

   • ✅ Keep

   • 📤 Move to OneDrive (GDPR_Archive folder)

   • ❌ Delete

4. Provides two buttons:

   • "Process Selected Actions" → Acts based on dropdown

   • "All Delete" → Deletes all files listed instantly

📁 Folder Layout

The folder layout for the GDPR cleanup tool is structured as follows:

• GDPR_Cleanup_Tool/: This is the main directory for the tool.

  • 🗎 CleanupTool.xlsm: This is the Excel file containing the VBA automation script.

  • 📁 OneDrive/GDPR_Archive/: This is the designated folder within OneDrive where files that are moved as part of the cleanup process are stored.

🔄 Workflow Diagram (Mermaid)

Here's the workflow diagram using Mermaid syntax for your GDPR-compliant file cleanup process:

graph TD;
    A[User selects folder] --> B[Scan for files older than 90 days];
    B --> C[Log to Excel: File, Path, Days Old];
    C --> D[Add dropdown: Keep / Move / Delete];
    D --> E[Click: Process Selected Actions or All Delete];
    E --> F[Apply logic: Move, Delete, or Keep];
    F --> G[Log result (success/fail) in Excel];

This diagram visually represents the steps involved in your automated file cleanup process.

🔍 Code: Scan Folder and Generate Log

Certainly! Here's the VBA code formatted for easy copying:

Sub ScanForOldFiles()
    Dim fso As Object, folder As Object, file As Object
    Dim ws As Worksheet, i As Long, selectedFolder As String
    Dim fileAge As Long

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set ws = ThisWorkbook.Sheets("Log")
    ws.Cells.Clear
    ws.Range("A1:D1").Value = Array("File Name", "Path", "Days Old", "Action")

    With Application.FileDialog(msoFileDialogFolderPicker)
        .Title = "Select Folder to Scan"
        If .Show <> -1 Then Exit Sub
        selectedFolder = .SelectedItems(1)
    End With

    Set folder = fso.GetFolder(selectedFolder)
    i = 2

    For Each file In folder.Files
        fileAge = Date - file.DateLastModified
        If fileAge > 90 Then
            ws.Cells(i, 1).Value = file.Name
            ws.Cells(i, 2).Value = file.Path
            ws.Cells(i, 3).Value = fileAge
            ws.Cells(i, 4).Value = "Keep" ' Default dropdown
            i = i + 1
        End If
    Next

    MsgBox "Scan complete. Files logged in sheet."
End Sub

▶️ Code: Process Selected Actions

Certainly! Here's the VBA code formatted for easy copying:

Sub ProcessSelectedActions()
    Dim ws As Worksheet, i As Long, lastRow As Long
    Dim filePath As String, action As String
    Dim archivePath As String

    Set ws = ThisWorkbook.Sheets("Log")
    lastRow = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
    archivePath = Environ("OneDrive") & "\GDPR_Archive\"
    If Dir(archivePath, vbDirectory) = "" Then MkDir archivePath

    For i = 2 To lastRow
        filePath = ws.Cells(i, 2).Value
        action = LCase(ws.Cells(i, 4).Value)

        If Dir(filePath) <> "" Then
            Select Case action
                Case "move to onedrive"
                    Name filePath As archivePath & Mid(filePath, InStrRev(filePath, "\") + 1)
                Case "delete"
                    Kill filePath
                Case Else
                    ' Do nothing for Keep
            End Select
        End If
    Next i

    MsgBox "Actions processed."
End Sub

You can copy this code directly into your VBA editor.

❌ Code: Delete All Listed Files

Certainly! Here's the VBA code formatted for easy copying:

Sub DeleteAllFiles()
    Dim ws As Worksheet, i As Long, lastRow As Long
    Dim filePath As String
    Set ws = ThisWorkbook.Sheets("Log")

    If MsgBox("Are you sure you want to DELETE all listed files?", vbYesNo + vbCritical) <> vbYes Then Exit Sub

    lastRow = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
    For i = 2 To lastRow
        filePath = ws.Cells(i, 2).Value
        If Dir(filePath) <> "" Then Kill filePath
    Next i

    MsgBox "All files deleted."
End Sub
