Extract text from WordPerfect workbooks (WKB)
To convert WKB workbooks to another format, you need Corel WordPerfect or other Spreadsheet software.
To convert other file formats to the "Legacy Workbook Data" file type, you need software like Corel WordPerfect or a similar tool.
The .WKB file extension primarily represents a WordPerfect Workbook file. These legacy spreadsheet files were created by older versions of the WordPerfect office suite developed by WordPerfect Corporation and later acquired by Corel. A secondary, completely unrelated use for the .WKB extension is as a Geodetic drawing file used by GEPRO Groma, a specialized land surveying and GIS software.
Modern users face severe challenges with .WKB files. The WordPerfect Workbook format is largely obsolete and entirely proprietary. It is not natively supported by modern web browsers, and attempting to open it in modern spreadsheet tools like Microsoft Excel often results in an error or garbled text. The GEPRO Groma geodetic files are similarly closed-source, requiring expensive, highly specialized survey software to render the coordinate data and line geometries.
To overcome these limitations, users must convert .WKB files. For workbooks, the best target formats are XLSX or CSV to ensure the data is readable in standard modern applications. Keep in mind that converting ancient spreadsheets often strips complex macros or custom formatting, leaving only the raw cell data. For GEPRO Groma files, converting to DXF or PDF is ideal for sharing survey data with CAD users.
Because both variations of the .WKB format are difficult to process, standard online converters frequently fail to parse them. Often, only the original legacy software or the specific GEPRO suite can properly export the data. However, just drag and drop your file to convert.guru to identify the format. We can inspect the file, extract raw text or internal content, and show you exactly what type of .WKB you have. If our analysis detects a supported embedded structure, conversion may still be possible.
Convert.Guru analyzes your WKB file, detects the exact format, and lets you read the text inside.
Users also converted PX, MLM, BKG, WKT and GEOJSON files.
If you want to convert WKB file to WKT or GEOJSON, you can use Corel WordPerfect or similar software from the "Legacy Spreadsheet & Survey Data" category. In the File menu, look for Save As… or Export….
To convert files to WKB, try Corel WordPerfect or another comparable tool in the "Legacy Spreadsheet & Survey Data" 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 WKB converter.
