DeviceCleanup – IT Device Cleanup Tool

IT Device Management

The simpler way to
clean up inactive
devices.

Cross-reference exports from any system, identify inactive machines automatically, and export a ready-to-use deletion list.

Add your sources — e.g. SCCM, AD, Lansweeper

Separate multiple sources with commas

Any CSV format

Import exports from SCCM, Active Directory, Lansweeper, Citrix, IPAM and more. Semicolon or comma separated — we handle both.

Auto date detection

Automatically recognises DD.MM.YYYY, YYYY-MM-DD, M/D/YYYY and more. No manual configuration needed.

Cross-source analysis

Reconcile data from multiple systems in one click. Always uses the most recent date across all sources.

100% local processing

Your data never leaves your machine. All analysis runs directly in the app — no server, no cloud, no account required.

Ready-to-use export

Download a clean deletion list as CSV or Excel — with YES/NO per source so you know exactly where to clean up.

Live Connect

Connect directly to AD, SCCM, Lansweeper, Intune or vSphere — no CSV export needed. Credentials stay local.

Why we built this

Because doing it manually
was never acceptable.

Every IT professional knows the situation: you are asked to clean up inactive devices across your environment, and suddenly you find yourself manually exporting data from four different systems, copy-pasting into spreadsheets, trying to reconcile device names with mismatched date formats, and hoping you haven't missed anything critical.

We have been there ourselves. What should have taken an hour turned into a full day of tedious, error-prone work — cross-referencing SCCM exports against Active Directory, Lansweeper, and IPAM, one row at a time.

The problem is not that the data isn't available. Every system has an export function. The problem is that none of them talk to each other — leaving IT teams to do the reconciliation by hand, every single time.

DeviceCleanup was built to eliminate exactly that. Upload your exports, map your columns, set your threshold — and get a single, consolidated list of inactive devices with a clear breakdown of which systems they exist in. No scripting required, no manual merging, no missed entries.

Built by IT professionals, for IT professionals.

How to use

Step 01

Define your sources

Type source names on the home page and press Add, or separate multiple with commas. You can also add or remove sources later in the workspace.

Tip: Use the same names your team already uses.

Step 02

Prepare your CSV exports

Most systems export CSV directly. Citrix and PowerShell exports often need a quick cleanup first.

Check your file in Excel: Delete row 1 if it starts with #TYPE, then run Text to Columns.

Open in Excel — delete row 1 if it contains #TYPE

Select column A → Data → Text to Columns → Delimited → Comma → Finish

Save as CSV UTF-8

Step 03

Upload and map columns

Upload each CSV and map the device name and last seen date columns. Use Delete to remove a source, or Add source to add more.

Supported formats: DD.MM.YYYY · YYYY-MM-DD · DD/MM/YYYY · M/D/YYYY with time.

Step 04

Run analysis

Set your inactivity threshold and click Run analysis. A progress bar tracks the analysis. Devices with no recognisable date appear as "No date found".

Step 05

Review and export

Each row shows YES/NO per source. Download the CSV to hand over to colleagues or import into a ticket system.

Note: The most recent date across all sources is always used.

Frequently asked questions

No. All processing happens entirely in your browser. Your CSV files are never sent to any server — they are read and analysed locally on your machine.

Open the file in Excel, delete row 1, then run Data → Text to Columns → Delimited → Comma, and save as CSV UTF-8.

Only if your file opens in Excel with all data in a single column. If columns are already separated, just save as CSV UTF-8.

The device was found in at least one source, but no recognisable date was present. These devices are still included since their activity status is unknown.

Yes. Use the "Add source" input at the bottom of the upload card to add new sources at any time. Use the Delete button on any source to remove it.

Any system that exports CSV — SCCM, Active Directory, Lansweeper, IPAM, Citrix, vSphere, Intune, and more.

Always the most recent one across all sources. This prevents devices from being incorrectly flagged if one source has outdated data.

90 days is a common starting point. Travelling employees or seasonal workers may warrant 120–180 days. Always verify against your company's device lifecycle policy.

No. DeviceCleanup is read-only. It identifies and lists devices — all actual deletions must be carried out manually in the respective systems.
