IT departments track hardware, software licenses, SaaS subscriptions, and network devices across multiple spreadsheets, CMDBs, and procurement systems. When the same laptop appears as 'Dell Latitude 5540' in one system and 'Latitude 5540 Dell' in another, inventory counts become unreliable. dataclean.to detects these duplicate technology records and consolidates them into a single, accurate asset inventory.
The Problem
Duplicate tech asset records lead to over-purchasing software licenses, inaccurate compliance audits, and wasted IT budget. A server listed twice inflates capacity planning numbers. A software license counted under two different product names means you might buy seats you already own. These duplicates accumulate as teams merge spreadsheets from different departments, migrate between ITSM tools, or import vendor CSV files with inconsistent naming. ISO/IEC 19770 IT Asset Management
How to Fix It
1
Export your tech asset inventory
Pull records from your CMDB, spreadsheet, or procurement system. Include serial numbers, asset tags, product names, manufacturers, purchase dates, and assigned users.
2
Upload the asset CSV
Import the file into dataclean.to. The tool auto-detects columns containing serial numbers, MAC addresses, and product identifiers that serve as natural deduplication keys.
3
Set deduplication criteria
Choose serial number as the primary match key for hardware. For software, use a combination of product name and version with fuzzy matching to catch naming variations like 'MS Office 365' vs 'Microsoft 365'.
4
Review flagged duplicates
Inspect each duplicate cluster. The tool shows field-by-field differences so you can confirm which records refer to the same physical device or license before merging.
5
Export the clean inventory
Download the deduplicated asset list. Use it for license compliance audits, refresh planning, or import into your ITSM platform with confidence in the numbers.
Frequently Asked Questions
How does the tool handle assets that share a product name but are different units?
Product name alone is rarely sufficient for deduplication. The tool uses serial numbers, asset tags, or MAC addresses as primary keys. Two 'Dell Latitude 5540' entries with different serial numbers are kept as separate records.
Can I deduplicate software licenses that use different naming conventions?
Yes. Fuzzy matching catches variations in vendor naming. 'Adobe Acrobat Pro DC' and 'Acrobat Pro DC 2024' can be flagged as potential duplicates based on configurable similarity thresholds.
What if a device was reassigned to a new user but kept its old record?
The tool flags records with the same serial number but different assigned users. You review these and decide which user assignment is current, keeping one consolidated record with the correct owner.
