What is a CDB file?
A .CDB file is a database file. Many different software applications use this file extension. Common examples include card databases for YGOPro simulators, the Symbian Phonebook Database used by old Nokia phones, and contact lists for Dymo CardScan. Because multiple programs use the .CDB extension, the internal data format varies. Some files use standard SQL or XML, while others are compressed ZIP archives.
How to open CDB files?
You can open a .CDB file with the original software that created it. For example, you can use SQLite for standard databases, SAP PowerDesigner for conceptual data models, or MikroTik WinBox for router address books. If you do not know the origin of your file, viewer.online/cdb analyzes .CDB files to identify their exact format and creator software, shows which programs can open the file, and usually previews it directly in your browser.
Software and tools
Many specialized tools create .CDB files. This includes ANSYS for command databases, Microsoft Cognitive Toolkit for machine learning datasets, and Stata for survey codebooks. You can often use command-line tools like standard database inspectors to view the raw data.
Summary
The .CDB extension is shared by games, mobile devices, and professional software. Because .CDB files use the known SQL format, viewer.online/cdb can safely open and display them online, eliminating compatibility problems.
