What is a CEX file?
The .CEX file extension is most commonly used for Energy Efficiency Certificate files generated by the Spanish Government's CE3X software program. However, because .CEX is used by several different industries, it has multiple possible meanings.
Besides energy certificates, .CEX files can store electrochemical experiment data and battery test results from Arbin Instruments or Zahner-Elektrik. They are also widely used as a SolidWorks Enterprise PDM Vault Export File by Dassault Systemes, containing administrative export data for product data management. Other uncommon uses include Caterpillar component exchange files and XML-based CardEditor design files.
How to open CEX files?
Because a .CEX file can have multiple meanings, you first need to know its origin. Energy certificates require the CE3X software. Battery test data requires Arbin MITS Pro. Vault export files require SolidWorks PDM.
If you do not know the origin of your file, viewer.online/cex can analyze .CEX files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
File Conversion
If you need to share the data in a more common format, we recommend file conversion on convert.guru. Depending on the exact type of your .CEX file, you might be able to convert it to .PDF for document sharing, .CSV for battery test data, or .XML for text-based analysis.
Summary
Since this file extension is shared by many different applications, viewer.online/cex is extremely useful for identifying, inspecting, and understanding .CEX files without installing software or dealing with compatibility problems.
