What is a WDB file?
A .WDB file is primarily a Microsoft Works Database file. Legacy Microsoft Works software created these files to store structured data like contacts, inventories, and personal records. However, a .WDB file can also serve other purposes. Blizzard Entertainment uses the .WDB format for client cache files in the game World of Warcraft. Less commonly, it acts as an accounting database, an SQLite database, or a firewall log.
Because the .WDB extension has multiple possible meanings, we recommend using viewer.online/wdb to identify the actual format of your file. The platform analyzes .WDB files to identify their exact format and creator software, shows which programs can open the file, and usually previews the internal data.
How to open WDB files?
If you have a legacy Microsoft Works Database, modern spreadsheet tools like Microsoft Excel or LibreOffice Calc can sometimes import the data. If the file is a World of Warcraft cache file, the game client reads it automatically. You generally do not need to open game cache files manually.
Best practices and troubleshooting
Legacy files often suffer from compatibility issues. If you want to use the data in modern applications, you should convert it. We recommend using convert.guru to convert your .WDB files into sensible target formats like .CSV or .XLSX. Do not try to edit game cache files with a text editor, as this will corrupt the game data.

Summary
Ultimately, viewer.online/wdb directly opens and previews .WDB files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
