DataTray

DataTray is a small Windows app that sits in your system tray and bundles five utilities for working with data files that would normally overwhelm Excel. It doesn’t require an account, has no ads or subscriptions, and the makers say it remains free.

The app brings several tools together in one place so you can peek into large files, convert between common formats, clean up duplicates, remove sensitive fields and compare two files side by side.

• Data Explorer: view the contents of huge files that would crash Excel.
• Data Converter: convert between CSV, JSON, XML and similar formats.
• Dedupe & Merge: find duplicates and combine multiple files.
• Clean & Anonymise: remove or mask sensitive information for safe sharing.
• Compare Files: highlight differences between two files side by side.

It’s aimed at data analysts, BI teams, data engineers, compliance and privacy officers, and IT staff who need a lightweight, local tool for handling large or awkward data files. More information is available at https://www.datatray.io/.
