What to expect

Frequently asked questions
What is kept when I convert XLSX to SLK?
SYLK is a plain-text spreadsheet interchange format that stores cell values, formulas, and basic formatting. Core numeric and text data carry over well, while rich formatting and modern features do not.
Why convert a workbook to SLK?
To move cell data into older or specialized programs that read SYLK, or to produce a simple text-based spreadsheet file for data exchange.
Does SLK support multiple sheets and charts?
No. SYLK is a single-sheet, cell-oriented format, so only one worksheet is exported and charts, images, and pivot tables are dropped.
How do I get back to a normal spreadsheet?
Open the SLK in Excel, LibreOffice Calc, or Google Sheets and save it as XLSX. Be cautious opening SLK files from untrusted sources, as SYLK is a known malware vector.
