What to expect

  • The spreadsheet becomes tag-based plain text; it is data, not a recalculating workbook.
  • Exact structure depends on the converter's XML schema, and formulas may appear as text or stored values.
  • Being plain text, the output is easy to read and archive but carries no spreadsheet interactivity.

Frequently asked questions

What does the XML output contain?
The WK3 spreadsheet is written out as structured, tag-based XML text representing the cells and their values. The exact tag structure depends on the converter's spreadsheet XML schema, but the data becomes plain, readable markup.
Why convert WK3 to XML?
XML is an open, plain-text format that any program or text editor can read, making it useful for archiving or feeding old Lotus 1-2-3 data into other systems. It frees the content from the obsolete binary WK3 format.
Where can I open the XML?
XML is plain text, so any text editor opens it, and dropping it into a browser tab gives a collapsible view. You do not run an XML file; other programs read and parse it.
What is lost in the conversion?
XML captures data and structure as text, so live spreadsheet behavior such as recalculating formulas does not exist in the output. Depending on the schema, formulas may be stored as text or as their last computed values rather than as active calculations.
