Open WB3 File
A WB3 extension file is a type of file created by Quattro Pro, a calculation program included in Corel WordPerfect Office.
About Quattro Pro
Quattro Pro was initially developed by Borland and later maintained and updated by Corel, however, as part of Corel's WordPerfect Office suite.
Quattro Pro has tools for quick calculations, which, however, are complex.
The WB3 file contains data, graphs, calculations and guidelines in a grid of calculation cells, just like in Excel or LibreOffice, and used for common business tasks or in personal finance.
Converting a WB3 Calculation Today
Using Microsoft Excel 2003, you can convert the WB3 calculation files into XLS and XLSX files, which are the native formats of Excel, always when the Quattro Pro file converter is installed.
However, it is worth mentioning that Excel 2007 and later do not support WB3 files.
The WB3 file extension is used by Quattro Pro 7 and 8.
