How to convert WK4 to XML
- Add your .WK4 file - drop it in the box above or click to browse.
- Convert it to .XML in a few seconds.
- Download your new .XML file.
What to expect
- Cell values and the row/column structure transfer into readable, tag-based text; the proprietary WK4 binary layout is left behind.
- WK4 carries no macros or scripting, so there is nothing executable to lose or worry about in the output.
- Lotus-specific formulas and fine formatting may not translate exactly; verify computed cells against the original.
Frequently asked questions
What does converting a WK4 worksheet to XML produce?
LibreOffice reads the Lotus 1-2-3 Release 4/5 binary worksheet and writes the cell data out as plain-text, tag-based XML. The rows, columns, and values become structured markup instead of a proprietary binary layout.
Why convert WK4 to XML?
WK4 is an obsolete binary format from a program IBM discontinued around 2013-2014, while XML is an open, text-based standard any tool can read. Converting rescues the data from a dead format into something durable and parseable.
Where can the XML output be used?
Because XML is just Unicode text, any text editor or browser opens it, and most programming languages and data tools can parse it directly. This makes the worksheet data accessible far beyond the original spreadsheet application.
Does everything in the worksheet survive?
Cell values and basic layout transfer reliably. Lotus-specific formulas and functions may not map cleanly, and presentation details like column widths or cell formatting may be simplified in the plain-data XML.
