Frequently asked questions
How much of my workbook survives conversion to SLK?
Cell values, formulas, and basic formatting transfer into the plain-text SYLK format. Advanced workbook features do not, so SLK is best for moving simple tabular data and formulas.
Why convert an XLSB to SLK?
SYLK is a simple text interchange format for moving cell data and formulas into programs that read SYLK but not the binary XLSB format.
What opens an SLK file?
Microsoft Excel, LibreOffice Calc, and Google Sheets all open SLK; from there it can be saved back to a modern spreadsheet format.
What gets dropped in the conversion?
SLK holds a single sheet, so any additional worksheets are lost. VBA macros that an XLSB can contain are not carried, and charts, images, and rich formatting do not survive.
