Extract text from Quattro Pro spreadsheets (WB3)
To convert WB3 spreadsheets to another format, you need Corel Quattro Pro or other Spreadsheet software.
To convert other file formats to the "Legacy Spreadsheet File" file type, you need software like Corel Quattro Pro or a similar tool.
The .WB3 file format is a legacy spreadsheet document created by Corel Quattro Pro versions 7 and 8, which was part of the Corel PerfectOffice suite. These files store cell data, mathematical formulas, charts, and macros within a structured binary grid.
Modern users face significant disadvantages when handling .WB3 files. It is a closed, proprietary format that is completely obsolete. You cannot open it natively in modern web browsers, and current versions of standard tools like Microsoft Excel or Google Sheets do not support it without specialized legacy plugins. Because it requires a paid WordPerfect Office subscription to open natively, sharing a .WB3 file usually guarantees the recipient cannot view your data.
To make this data usable today, you must convert the .WB3 file to an open standard like XLSX, CSV, or ODS. Converting to CSV is excellent for raw data preservation but will strip away all charts, formatting, and formulas. Converting to XLSX retains more structure but may still break complex legacy Quattro Pro macros.
This file format is difficult to open or convert because it relies on the internal Microsoft Compound (OLE Structured Storage) binary architecture, paired with Corel's proprietary data structures. Because the format is undocumented, standard online converters usually fail to process the spreadsheet cells correctly.
Convert.Guru analyzes your WB3 file, detects the exact format, and lets you read the text inside.
Users also converted QPW, WB2 and WQ2 files.
If you want to convert WB3 file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Corel Quattro Pro or similar software from the "Legacy Spreadsheet Data Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to WB3, try Corel Quattro Pro or another comparable tool in the "Legacy Spreadsheet Data Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WB3 converter.
